Conjure Shadow wisps

You Conjure 2 Shadow wisps from the Shadowfell within 10 feet of a point you can see in range. 

A summoned creature disappears when it drops to 0 hit points or when the spell ends.

The summoned creatures are friendly to you and your companions. Roll initiative for the summoned creatures as a group, which have their own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions.

The GM has the creatures statistics. 

At Higher Levels. When you cast this spell using certain higher-level spell slots, you choose one of the summoning options above, and more creatures appear: twice as many with a 5th-level slot and three times as many with an 7th-level slot, and 4 times as much with an 9th level spell slot
