Shape-shifter adept

General Feat (Prerequisite: A feature that allows you to shape-shift or a spell with the Shapechanging tag.)

You gain the following benefits.

Ability Score Increase. Increase your Intelligence, Wisdom or Charisma score by 1, to a maximum of 20.

Speed shifting. If originally using an action to use a feature in order to shape-shift only yourself (e.g. Wild Shaping) or cast a spell with the Shapechanging tag (e.g. with Disguise Self) only targeting yourself, you may instead use a bonus action. If originally using a bonus action, you instead may use a reaction (taken when you take damage but before applying resistances or other features, etc). If originally using a reaction, it can be considered a free action on your turn. If originally using more time than an action, the amount of time halves, unless it would now take less than or equal to 6 seconds, in which case it would take an action.

Repeatable. You can take this feat more than once, stacking each time. E.g. if you took this feat twice, an action to shape-shift would only practically cost a reaction.
