Ability Mastery and Resets
Ability mastery has move-specific effects; for Eikonic abilities it can also allow equipping the move under any Eikon. The cited guide says spent points can be reset.
How it works
IGN explains that mastering an Eikonic ability allows it to be slotted with any Eikon, while Game8 notes that mastery effects vary by ability and can change particular properties. Game8 also says players can reset all unlocked abilities or individual skills and recover spent points.
When it helps
Before mastering a move, inspect its specific effect: some masteries affect properties while others unlock cross-Eikon equipping. If you want to experiment, the cited guide describes point resets as an option.
The tradeoff
Mastery requires additional ability points, and its benefit differs by move; the supplied sources do not establish current costs or whether every version handles resets identically.
Your next step
Select an ability in the Abilities menu and inspect its upgrade and mastery details; check the cited reset option’s current menu behavior before using it.
