1st-level necromancy
You manipulate the perception of one creature in range that you can see. The target must make a Wisdom saving throw, and does so with advantage if you or your companions are fighting it. If the target fails its save, you can choose one willing creature within range (including yourself) to become invisible to it for the duration. Whenever the target takes damage it can repeat the saving throw, ending the effect on itself on a success.
When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature and choose one additional willing creature for each slot level above 1st. The chosen creatures are invisible to all affected targets.
