You call forth a crow's nest from the Eleteth Delta; a headless bloat full of hundreds of undead crows and ravens that it releases when threatened. Choose an area within range. The crow's nest appears in the area you chose in an unoccupied space within 10 feet of it. The crow's nest disappears when it drops to 0 hit points or when the spell ends.   The crow's nest is friendly to you and your companions for the duration. Roll initiative for the undead, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don’t issue any commands to the crow's nest, it defends itself from hostile creatures but otherwise takes no actions.   If your concentration is broken, the crow's nest doesn’t disappear. Instead, you lose control of it and its swarms of crows, they becomes hostile toward you and your companions, and they might attack. An uncontrolled crow's nest can’t be dismissed by you, and it disappears 1 hour after you summoned it. The DM has the crow’s nest's statistics.
