A coin is tossed in the air, and the coin disappears. After the caster flips the coin, a demonic entity appears somewhere within a 5ft cube of the caster. The creature is an imp, dretch, quasit or a swarm of gibberlings. During the round that this was casted, the creature is an illusion, and it’s appearance can be changed to take the form of another listed creature and can move freely. Every other round, the creature becomes physical, and only stays physical for one round. So long as the creature is physical, it can take an action and a movement action, which is controlled by the caster. When the creature becomes an illusion and then becomes physical, it’s hit points replenish.
