Transfigure Ability

You touch a willing creature and trans-mutate their base physiology and intellect in order to bestow them with a temporary alternate ability score, substituting your spellcasting ability score with a choice ability score of the target's. If the creature is not willing, they must make a Charisma saving throw to resist the effects of this spell. Choose one of the following effects; the target gains that effect until the spell ends.

Fighter's Strength. The target gains a Strength score equal to that of your spellcasting score.

Rogue's Dexterity. The target gains a Dexterity score equal to that of your spellcasting score.

Barbarian's Constitution. The target gains a Constitution score equal to that of your spellcasting score.

Wizard's Intelligence. The target gains an Intelligence score equal to that of your spellcasting score.

Cleric's Wisdom. The target gains a Wisdom score equal to that of your spellcasting score.

Bard's Charisma. The target gains a Charisma score equal to that of your spellcasting score.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional creature for each slot level above 3rd. Each additional creature gains the same effect from the original target of the spell.
