Mastery Trees

A per-technique node tree spent with that technique's Extra copies (e.g. Limitless Extra) - each node buffs one specific move (damage, cooldown, range, etc.) and adds a flat stat bonus. This is what technique descriptions mean by "awakening tree" or "mastery tree." Every technique, clan, weapon, Heavenly Restriction, and Ten Shadows shikigami has its own separate tree - far too many nodes to catalog individually, but the shape is consistent across all of them.
