Rewards from Expert additionally include High Windwyrm's Tail, which alongside Windwyrm's Greatspheres can be used to craft Wind-attuned High Dragon weapons with High Mercury's Bane.
Additionally, weekly clears from Expert additionally include small amounts of High Windwyrm's Horns, which alongside Windwyrm's Greatspheres and High Windwyrm's Tails can be used towards enhancing Wind-attuned High Dragon weapons into tier 2, significantly increasing its power against enemies outside of High Mercury.
HP isn't too much of a concern, as all adventurers should be able to withstand the unavoidable damage High Midgardsormr inflicts at the beginning of the fight if they have sufficiently strong equipment, and a healer was used, which is highly recommended if the entire team is on the weaker side (e.g. if all players are newer accounts with bare minimum equipment).
Weapons[ | ]
Crafting Void Bane or Chimeratech weapons, or better, can improve your adventurer's performance (especially if it's Chimeratech) in the quest, though technically optional. Still, if possible, at least equip your adventurers with Void Bane weapons at minimum.
Generally speaking, if you're able to clear Volcanic Chimera Strike: Standard (and preferably, also its Expert difficulty), you should obtain materials from it to create a Chimeratech weapon, as it should be more powerful than void bane weapons, especially once other punisher modifiers are factored in - the (Flame) High Midgardsormr's Bane +30%If the user is attuned to Flame: increases damage to High Midgardsormr by 30%. eats into the punisher bracket that is also used by Me and My Bestie!'s Burning Punisher +30%Increases damage to burning enemies by 30%.. It is also easier to build compared to the Void bane weapons, but if you already have them anyway, feel free to use them.
Prime Overdrive DPS - These sword-wielding adventurers play largely the same role - prime ODPS deliverers as swordsmen and a major source of DPS, as well as baiting High Midgardsormr's attacks.
Gala Mars significantly improves all of their DPS. However, there are many other suitable dragons who still provide excellent damage output.
The Prince disfavors Konohana Sakuya, due to his relatively weak skill slice.
Marth can provide significant amounts of direct and indirect buffing to the entire team with his skills (Strength Up, Attack Rate Up, and even 100% Skill Gauge Charge Up), and Gala Mars is hence a perfect fit for him.
Chrom and Naveed prefers running Konohana Sakuya before any other dragon not Gala Mars, due to their very high skill slices.
Standard DPS + Yukata Cassandra - These standard DPS units deal damage to the boss. For Yukata Cassandra, Strength-based dragons enhance her effective damage output from both her and everyone else due to her Fluorescent Fish buff from Goldfish of the HereafterLv. 1: Restores HP to all teammates with 58%Recovery Potency and grants all teammates the "Fluorescent Fish" effect for 30 seconds. Fluorescent Fish grants overdamage based on 20% of the user's strength. [7734 SP]
Lv. 2: Restores HP to all teammates with 72%Recovery Potency and grants all teammates the "Fluorescent Fish" effect for 30 seconds. Fluorescent Fish grants overdamage based on 30% of the user's strength. [7734 SP]
Lv. 3: Restores HP to all teammates with 87%Recovery Potency and grants all teammates the "Fluorescent Fish" effect for 30 seconds. Fluorescent Fish grants overdamage based on 40% of the user's strength. [7734 SP].
The dragons are mostly interchangeable, aside from Gala Mars being stronger than anyone else.
Ezelith and Mikoto like having Arctos to complement their very high critical rates if Gala Mars is unavailable.
On other adventurers, using Arctos likely requires a different wyrmprint and chain co-ability setup than normal, prioritizing Critical Rate Up abilities.
Rena and Nobunaga like having Konohana Sakuya to boost their massive skill slices if Gala Mars is unavailable.
Gala Mym has an unusually large practical standard attack slice if played sub-optimally, and Yukata Cassandra has no skill damage and also scales off strength, and hence disfavors Konohana Sakuya.
Apollo may help with burn uptime, especially on Xania. Note that Gala Mym cannot burn with Apollo due to his skill being overwritten with Gala Brunhilda's, though the (Flame) Burning Punisher +20%If the user is attuned to Flame: increases damage to burning enemies by 20%. ability will still function.
Spooky Flamewyrm - Halloween Mym's contribution comes from both a relatively large standard attack slice, as well as the supportive effects on her skills, but she can also burst down very hard with her dragon form, which is the strongest among Flame dragons, even when compared with Gala Mars.
Konohana Sakuya is not a good choice for Halloween Mym due to her very low skill damage slice.
I'm a healer! - The on-element dragons provide differing benefits to the healer.
Gala Mars lets the healer dish out some damage in dragon form, and also immediately reenables the use of all their skills.
Phoenix can be used to increase the healers' HP, which may make it harder for the healers to be defeated by taking too many hits, especially since she also grants a potent regen heal.
As the healers' healing output are more than sufficient, even when lightly equipped, it is possible to experiment with off-element dragons for access to strong buffs.
Pop-Star Siren can be used to grant the entire team significant strength and Energy buffs.
Freyja is similar, but trades strength buffs with a regen heal, and instantly energizes instead of having to cast twice.
Wyrmprints[ | ]
All adventurers should equip their standard wyrmprints.
A Shapeshift Prep +10%Fills 10% of the dragon gauge at the start of quests. wyrmprint on the buffer and/or healer can help with making shapeshifting available earlier.
Party Roles[ | ]
DPS/Hybrid DPS[ | ]
These units will be doing the majority of the DPS, and provide buffs/debuffs if applicable.
Don't bring more than one Emma or one Halloween Mym (no duplicates; it's OK to have Emma and Halloween Mym together) in the whole composition.
Due to the low difficulty of the quest, almost every adventurer and composition will work for this quest. This lists only the more common adventurers for the quest, with short descriptions.
High damage, very high break damage, minor Defense Down debuff, doesn't inflict burn so that burn uptime may be improved if someone else already burns.
Healing-focused healer with Stun relief. Better at patching up individual damaged adventurers than Halloween Lowen or Yukata Cassandra, and can bail out stunned teammates.
Offensive support healer. The Fluorescent Fish buff from her Goldfish of the HereafterLv. 1: Restores HP to all teammates with 58%Recovery Potency and grants all teammates the "Fluorescent Fish" effect for 30 seconds. Fluorescent Fish grants overdamage based on 20% of the user's strength. [7734 SP]
Lv. 2: Restores HP to all teammates with 72%Recovery Potency and grants all teammates the "Fluorescent Fish" effect for 30 seconds. Fluorescent Fish grants overdamage based on 30% of the user's strength. [7734 SP]
Lv. 3: Restores HP to all teammates with 87%Recovery Potency and grants all teammates the "Fluorescent Fish" effect for 30 seconds. Fluorescent Fish grants overdamage based on 40% of the user's strength. [7734 SP] skill can elevate teamwide DPS and especially the hit count (for activating combo-based abilities), and also carries a high amount of burst and regen healing that are more than sufficient to cover all unavoidable damage, especially if paired with outside sources of defensive buffs (be it from a different adventurer, or shared skills), though she cannot trigger doublebuff effects on her own. Compared to Halloween Lowen, she prefers Strength-based dragons.
Grace provides a very large Life Shield which can protect adventurers from being afflicted and blocks knockback while the shield is not completely destroyed. Her Defense Up buff is much higher, at 100%, too. Does not have Stun res, but the affliction is blockable with a large life shield.
Healer with some attacking power on the side. Has slightly higher personal DPS than other healers here, and can provide additional Burn uptime. Does not have Stun res.
General Party Setup[ | ]
The two real requirements for general compositions are as follows:
One of the adventurers in the composition must be able to heal the entire team if desired (to reactivate any HP-based abilities).
One of the adventurers should behave as the close range baiter. Usually, this job falls to either the DPS with the shortest reach, or the host (Player 1).
Having multiple adventurers with similar reach may cause baiting issues, though it can be worked around with careful play.
Example 3: in this 3DPS composition, as no one is a melee adventurer, whoever is hosting should perform close-range baiting.
If Gala Sarisse was the host, she should ideally perform close-range baiting.
Attacks and Patterns[ | ]
Calamitous Storm[ | ]
This is the fight's initial "HP check" blast.
Any adventurer with Skill Prep +100%Fills 100% of skill gauges at the start of quests., such as Halloween Lowen with From Whence He Comes, should use defensive skills such as Here's a treat for you!Lv. 1: Restores HP to all allies with 72%Recovery Potency, and increases the entire team's max HP by 5% for the remainder of the quest. Once HP buffs reach the limit of 30%, an HP recovery effect is granted instead. [11832 SP]
Lv. 2: Restores HP to all allies with 90%Recovery Potency, and increases the entire team's max HP by 10% for the remainder of the quest. Once HP buffs reach the limit of 30%, an HP recovery effect is granted instead. [11832 SP] and You won't trick me!Lv. 1: Restores HP to all allies with 31%Recovery Potency and continues healing over the next 15 seconds with 25%Recovery Potency every 2.9 seconds. It will also increase the entire team's strength by 8% for 60 seconds. This strength increase will not stack. [5916 SP]
Lv. 2: Restores HP to all allies with 36%Recovery Potency, continues healing over the next 15 seconds with 29%Recovery Potency every 2.9 seconds, and increases the entire team's defense by 10% for 5 seconds. It will also increase the entire team's strength by 8% for 60 seconds. This strength increase will not stack. [5916 SP]
Lv. 3: Restores HP to all allies with 44%Recovery Potency, continues healing over the next 15 seconds with 35%Recovery Potency every 2.9 seconds, and increases the entire team's defense by 10% for 5 seconds. It will also increase the entire team's strength by 8% for 60 seconds. This strength increase will not stack. [5916 SP] to reduce the damage taken, though it is entirely optional.
For Halloween Lowen and Grace, the order is important: use their second skills before their first skills, as the blast damage will clip the animation of the currently cast skill too early otherwise.
Afterwards, if possible, heal it back up ASAP to restore HP conditional abilities. You won't trick me! will provide HP Regen healing, but one may opt to run other skills to make it go a bit faster.
Shared skills can help with further mitigation and/or healing.
You can't iframe it, however if you are a melee character then you can hold down Force Strike to not get knocked back.
Sword-wielding adventurers can also attempt this sequence of actions: dodge roll towards High Midgardsormr, attack twice, force strike, then attack five times without using a force strike. Due to knockback immunity between the third and fifth attack on the second string of attacks, they will also not be knocked back, and this also improves SP gain.
Lance-wielding adventurers can also attack immediately, but make sure that the attack string is ongoing (restart the string if it's about to end at the fifth attack) and do not use a force strike; lances have natural knockback immunity that is strong enough to prevent movement from the opening blast's knockback while within the string of attacks. Alternately, hold a force strike only after the fifth attack has landed.
Axe-wielding adventurers should just simply attack immediately without ever breaking the chain or force strike. Axes have natural knockback immunity that is strong enough to prevent movement from the opening blast's knockback.
Trident Tempest[ | ]
High Midgardsormr faces the closest adventurer and spits out three gales, in a cone pattern. This attack is unavoidable within the marker, and deals strong damage if physical contact is made. The close-range baiter should bait this away from the rest of the DPSes.
Normally, adventurers should move away and avoid it, but with precise timing, some skills such as The Prince's Exalted FireLv. 1: Deals 1 hit of 1194% flame damage to enemies in a line. [4880 SP]
Lv. 2: Deals 1 hit of 1327% flame damage to enemies in a line, and reduces defense by 5% for 10 seconds with 100% base chance. This defense reduction effect will not stack. [4880 SP]
Lv. 3: Deals 1 hit of 1474% flame damage to enemies in a line, and reduces defense by 5% for 10 seconds with 100% base chance. This defense reduction effect will not stack. [4880 SP] can let the adventurer physically dodge the hitboxes, if you have these skills ready, in later instances of Trident Tempest.
The close-range baiter should take position afterward to bait High Midgardsormr towards the middle of the arena, so that there's space for movement later on.
Dash + Spin Attack + Backdash[ | ]
High Midgardsormr faces the closest adventurer, charges, performs a spin attack, and backdashes.
The charge and the spin attack has a chance to inflict Stun.
Sometimes, High Midgardsormr will perform an uppercut instead of a spin attack.
If you dodge roll the spin attack for iframes, you may need to dodge roll twice in a row, as the roll's iframes are not quite long enough to cover the entire attack.
Spits x3[ | ]
High Midgardsormr faces the closest adventurer (see a pattern here?), and spits towards them three times. The close-range baiter should skill or dodge them, making sure to bait them away from the rest of the DPSes.
These spits will linger on the battlefield for a while, causing damage to anyone caught in them. It is possible to safely move through these mini tornadoes with dodge rolls, if desired.
If High Midgardsormr was baited too close to a wall, it might get tricky to bait the spits without getting hurt.
Trident Tempest (8-Way)[ | ]
This variant of Trident Tempest sweeps an entire circle and also deals much higher damage than the normal variant. Avoid lingering in the purple action markers.
High Midgardsormr will always call out this attack with "I shall rend you asunder!"
Tattered Sky + Storm Chaser[ | ]
High Midgardsormr will spawn a red stack marker targeted on the closest adventurer.
If the adventurer has a dragon ready, they should shapeshift now and dragon tank the stack marker.
If the adventurer doesn't have a dragon ready, all adventurers should get together and split the damage. A defensive healer can help with this.
Healers with only HP Regen healing skills ready should activate them now so that the healing can cover all adventurers for the next attack.
Afterwards, High Midgardsormr will then spawn purple chaser markers on all adventurers. Avoid overlapping other adventurers' with their markers to minimize damage taken.
A sufficiently large Shield or Life Shield can block its damage entirely.
Continue normal baiting, making sure to never bait High Midgardsormr too close to a wall. Avoid lingering within the purple action markers.
Summon Help[ | ]
High Midgardsormr summons some golems to help him out. Defeat them ASAP, especially the big one - he is the source of the giant map-wide purple action marker, and if it fills up, it will deal damage strong enough to wipe out the entire team, using up a revive. High Midgardsormr will also try to keep you busy; see the following section for his attacks.
Most compositions with at least Chimeratech or HDT1 weapons as of writing should clear Expert difficulty by this point due to the general power levels of current adventurers.
Further moves will be listed for reference, though the later moves are unlikely to be seen in the average run now.
The battlefield can get a bit confusing to read due to the additional enemies and red action markers, but the close range baiter should try their best to bait the attacks away from the rest of the group.
The golems should be defeated by the time High Midgardsormr finishes the above chain of attacks.
Continue normal baiting, making sure to never bait High Midgardsormr too close to a wall. Avoid lingering within the purple action markers.
The close-range baiter will have to quickly make it back to High Midgardsormr once the 8-way attack launches past them to bait the spits away.
After High Midgardsormr backdashes here, everyone should return to the center of the map in preparation of the next attack.
Gale Blast[ | ]
High Midgardsormr will spawn four very large tornadoes across the top of the map. These tornadoes will move across the map, starting from the tornado with dust clouds underneath.
At Expert difficulty and lower, there are three methods of dealing with these tornadoes.
The old method is to go under the tornado with the dust clouds, and move upwards around the map as the tornadoes launch.
It is possible to dodge roll consecutively while passing through these tornadoes, taking advantage of the dodge roll's iframes.
This tactic is not possible in Master difficulty, so you may have to "unlearn" it in that fight once you plan to clear that difficulty.
If shapeshifting is available, it is also possible to dragon tank the tornadoes.
In Expert difficulty and lower, dragon tanking with a skill will not decrease dragon time, as it is not an unavoidable attack.
High Midgardsormr will also try to keep you busy while you avoid the tornadoes.
Continue normal baiting once all tornadoes have passed, making sure to never bait High Midgardsormr too close to a wall. Avoid lingering within the purple action markers.
Nearly all compositions with at least Void Bane weapons as of writing should clear Expert difficulty by this point due to the general power levels of current adventurers.
Further moves will be listed for reference, though the later moves are extremely unlikely to be seen in the average run now.
Identical to previous instance, but High Midgardsormr will immediately follow up with a Trident Tempest, so the close-range baiter must not be separated from him.
Dash + Spin Attack[ | ]
Continue normal baiting. Be prepared for Gale Blast and Tattered Sky combo.
Gale Blast + Tattered Sky + Storm Chaser[ | ]
Both Gale Blast's tornadoes and Tattered Sky's stack marker will appear at the same time.
This is a very good time for the targeted to dragon tank, move to someplace safe (not affecting other adventurers), and use a skill to tank it.
Continue normal baiting, making sure to never bait High Midgardsormr too close to a wall.
By this point, High Midgardsormr should be defeated in Expert difficulty if you had the minimum recommended equipment, even with poor DPS uptime.
The quest likely ends much earlier if your equipment was significantly better than the minimum requirement.
This was originally the point where your quest would be subject to a failure by the quest timer running out, and it was a real risk back when High Midgardsormr's Trial was first released.
This guide includes the entire moveset for the first five minutes of the quest as a reference.
