Ability base classes

Every class here extends a Mine Mine no Mi type and encodes a technique shape that addons kept rewriting. Pick the one closest to your technique, extend it, and fill in what it asks for.

Read the class comment before departing from a base class

Most of the code in these classes exists because something shipped broken first. The class comments usually record what went wrong, and why the obvious simplification brings the bug back.

Damage units differ between classes

Some base classes deal damage for you, from a number you return. That number goes to the base mod's pipeline as is, so it is reduced by x0.4 like any ability damage (see Damage). Return AkumaAbilityHelper.scaledDamage(realHp) wherever a class asks for a damage value, unless its page says otherwise.
