You gain the following benefits.

Ability Score Increase. Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20. (when taken via normal level ups, if taken via quest reward, you can't use the ability score increase)

Double Time. When you use "Reactive Spell" on one of your allies, you double the speed of the targeted ally until the end of their turn.

Reactive Spell. When an Ally willingly leaves your reach, you can take a Reaction to cast a spell on them. The spell must have a casting time of one action and must target only that creature.

Battlefield Savior. When you cast a healing spell as part of "Reactive Spell", you can choose to take 1d4, 1d6, 1d8, 1d12, or 1d20 necrotic damage, the target of your spell regains hit points equal to the amount of damage you took.
