Switcheroo

You transfer your powers with that of another creature. When you cast this spell, choose a creature within range, that creature has to make an Intelligence saving throw. When a creature fails the save, you can switch one of your ability scores with that of the creature until the end of your next turn. Choosing to switch Constitution doesn't affect either the hit point maximum or the current hit points of you and that creature.

At higher levels. When you cast this spell using a spell slot of a higher level, you may target one additional ability score for each second slot used above 3rd.
