Magic connects all things, in both life and death. You can see these connections, the possible spells a creature can cast - and steal them with a word and a gesture.

Make a melee spell attack against a creature within your line of sight. On a hit, you 'borrow' one of their spells and can use it as you wish - either to harm the creature, or another, creating the appearance of "friendly fire". You can only steal a spell up to your level, but you also ignore the creature's spent spell slots. Until the spell ends, you can make the attack again on each of your turns as an action.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the spell levels available increases by 1d6 for each slot level above 3rd.
