Aldra's Surprise Rush

When a creature within 5 feet of you makes a melee attack roll against you, you can instantly teleport to a space within 5 feet behind the attacker, forcing the attack to miss.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you are able to teleport an additional number of times, in response to being targeted by a melee attack, equal to the level of the spell slot used until the start of your next turn.
