Crow Storm

You conjure a crow (use Raven stat block) with the storm effect. When a creature with the storm effect is conjured, it is replicated once for every spell you have cast during this combat prior to casting Crow Storm. The creatures created by the storm effect do not have the storm effect. All crows created by this spell take their turns directly after yours.

When casting Crow Storm, the player must recite the following poem:

Storm crow lonely, boon for a birder. / Storm crows together, likely a murder.

At Higher Levels: For every level this spell is cast at above 4th, it creates 1 more crow with the storm effect.
