Mana Circles

Mana Circles are a "skill tree"-like feature that allows adventurers to unlock and upgrade skills and abilities, as well as gain stat boosts.

Overview
Mana Circles consist of five floors with ten nodes each, for a total of fifty nodes, which can be unlocked using Mana and other materials to make adventurers stronger. Each adventurer has their own mana circle, and for each specific adventurer's mana circle, refer to each adventurer's specific page.

Mana Circle Node Unlock
To unlock a node, simply tap the node with the benefit to unlock (e.g. Str +11). A pop-up should appear to confirm unlocking the node, and once confirmed, the node will light up and immediately unlock the benefit for the adventurer.

Mana Circle Unbind
Players must complete lower floors in order to unbind higher floors. For example, in order to unbind the second floor, a player must first unlock all the mana circle nodes on the first floor, and then pay the material cost to unbind to floor 2.

Additionally, lower rarity adventurers may be locked out of higher floors. In order to access all of the upper floors, a player will need to promote the lower rarity adventurers all the way to.

Mana Circle Materials
Unlocking nodes in the Mana Circle will require certain amounts of a variety of materials:

Mana Circle Variant Costs
Some adventurers have differently-formatted Mana Circles, and thus have different total unlock costs:

This type has lower-cost mana circles than those of an ordinary adventurer. The adventurers in this category are all available for free from the Main Campaign: 

This type has lower-cost mana circles than those of an ordinary adventurer (though not as low as Type 4.2), and has no adventurer stories to unlock. There is currently only one adventurer in this category,.

This type has the adventurer's first Ability already unlocked when at 0 mana circle nodes. This is likely because it grants permanent access to a unique transformation. There is currently only one adventurer in this category,.

This type has the adventurer's first Ability already unlocked and at level 2 when at 0 mana circle nodes. There is currently only one adventurer in this category,.

This type has the adventurer's first Ability already unlocked when at 0 mana circle nodes. This is likely because the adventurer has access to a unique mechanic or transformation from their first Ability. 

This type has only 1 level available on both skills, and has no adventurer stories to unlock. There is currently only one adventurer in this category,.

This type has the adventurer's first Ability and force strike already unlocked when at 0 mana circle nodes. This is likely because the adventurer has access to a unique force strike from their first Ability. 

This type has only 1 level available for the third Ability. There is currently only one adventurer in this category,.

This type has the adventurer's force strike already unlocked when at 0 mana circle nodes. This is likely because the adventurer has access to a unique force strike that makes up most of their combat potential. There is currently only one adventurer in this category,.

This type completely lacks Force Strike nodes and has the adventurer's first Ability already unlocked when at 0 mana circle nodes. There is currently only one adventurer in this category,.

Mana Circle Node Recommendations
All mana circle nodes are considered good investments as every node provides something (stats, skills, abilities, etc.) of value. Since all of the nodes on a floor must be unlocked before proceeding to the next floor anyway, all nodes should be unlocked regardless.

If mana is a limiting resource, however, recommendations then start leaning towards:
 * Prioritize mana circle nodes which increase the most Might. Every node increases Might, but other nodes may increase more Might than others. These will help unlock higher level content to help progress in other areas (e.g. Being able to do harder raids for more materials for weaponcrafting or unlocking nodes which require materials).
 * Refer to character pages for how much Might each mana circle node gives.
 * Learning Force Strike is a solid node to invest in due to it being the only ability which can break enemy shield guards.

Mana Circle Completion Bonus
Upon unlocking and completing 50 nodes on an adventurer's entire mana circle, the adventurer will be given an HP and Str bonus. These bonuses vary between adventurers, so refer to the specific adventurer pages for exact values.

Display Options
In the settings menu (in the Green Book on the top-right of the screen), there is an option to view Mana Circles in a 2D form rather than 3D. This display is functionally the same as the 3D option, but reduces loading time considerably on older devices.

Additionally, the 2D option allows the player to view Mana Spirals before actually unlocking the spiral on a particular adventurer, a feature that the 3D option lacks.

Mana Spiral
Some adventurers (usually older ones) have access to the Mana Spiral, an additional 20 nodes accessible after completing the 50 nodes of the Mana Circle. Unlike the Mana Circle, these nodes must be unlocked in a specific order, one-by-one, instead of the 10-nodes-per-floor approach.

The boosts from these nodes tend to be very powerful, and can change an adventurer's playstyle or performance considerably.

Mana Spiral Upgrades
The types of upgrades that can come from Mana Spiral Upgrades are:
 * Mc StatusUp HpAtk.png HP & Str Increase
 * Upgrade Skills
 * Upgrade Abilities
 * Mc Unbind Level.png Increase Maximum Level
 * Mc Advanced Training.png Increase Standard Attack Damage

Mana Spiral Materials
Unlocking nodes in the Mana Spiral require certain amounts of a variety of materials:
