Aspect of Death

You focus threads of magical energy around you which coalesce into the aspect of death, an avatar made of bones, which surrounds you and fights on your behalf. The avatar is Large, is centered on you, and moves with you. While it is summoned, it protects you from foes; you are considered behind three-quarters cover at all times, have resistance to all damage, are immune to being grappled, and no other creature can enter the space of the avatar.

In addition, while active, you gain a +1 bonus to spell attack rolls and saving throws, and when you cast a spell that deals bludgeoning, piercing or slashing damage, it is cast with a spell slot 2 levels higher than the one expended (to a maximum of 9th level).
