Allana's Conjure Spider Swarm

You conjure 8 giant wolf spiders and appear in unoccupied spaces that you can see within range.

Each spider 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 has its 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 DM has the creatures’ statistics.

At Higher Levels. When you cast this spell using certain higher-level spell slots, more creatures appear: twice as many with a 5th-level slot, three times as many with a 7th-level slot, and four times as many with a 9th-level slot.
