Signature Abilities
Acquiring Signature Abilities
Before a character can purchase a Signature Ability or any of its upgrades, the character must "attach" that ability to the bottom of one of their current in-career Talent Trees. Once a Signature Ability has been attached to a tree, no other Signature Abilities may be attached to that tree, and the attached ability cannot be removed or switched to a different tree.
A character can only acquire a Signature Ability from their career and can only attach that ability to in-career Talent Trees.
Signature Ability Breakdown
A Signature Ability is composed of three elements: the Nodes linking it to a Talent Tree, the ability's basic form, and a series of Upgrades that augment the ability.
Nodes
To be able to attach a Signature Ability to a tree, the character must own all of the talents along the bottom row of the destination Talent Tree that match up with the active Nodes on the Signature Ability.
Ability Basic Form
When a character acquires a Signature Ability, they must first purchase the Basic Form of the ability. This takes up the entire first row of the Signature Ability tree and is purchased with Experience Points. The experience cost of the Basic Form is listed in its box.
Upgrades
After the character has purchased the Basic Form of the Signature Ability, they can further customize the ability by purchasing Upgrades. Upgrades are purchased with Experience Points, and each upgrade may only be purchased if it connects to the Basic Form of the ability or a previously purchased upgrade. The experience cost of each Upgrade is listed in its box.
