You transform a staff or bundle of sticks into serpents. When you do, choose an unoccupied space within 30 feet to throw the staff or bundle of sticks. The effect of this spell varies based on the material component used to cast it.   When you throw a staff, it transforms into a giant constrictor snake. When you throw a bundle of sticks, it transforms into a swarm of poisonous snakes. The creature’s current and maximum hit points increase by 2d8 when it is created.   The created snake or swarm is friendly to you and your companions. Roll initiative for the creature. It obeys any verbal commands you issue it (no action required by you). If you don’t issue any commands to it, it defends itself from hostile creatures, but otherwise takes no actions. If the snake or swarm has an effect that causes a target to make a saving throw, the effect uses your spell save DC, unless the snake or swarm’s DC was already higher.   At the end of the spell, or if the snake or swarm is reduced to 0 hit points, it turns into a broken staff or snapped bundle of sticks, respectively.
