Wizologer

This mob would be an Illager type enemy with magical powers. It would have a cool purple blue wizard hat that glows blue slightly. It would have a verity of powers such as fire, ice, lightning, soul, and shield. Its fire attack would shoot a small fireball, that would burn any players it hits and deal some damage. The ice attack would freeze or slow down all players in a small area around it. The lightning attack would channel a bolt of lightning that attaches to the closest player and deals shock damage to them, and any other players that walk through the chain of lightning. The soul attack would kill a few mobs near it to steal their souls and put the Wizologer into shadow form making it invulnerable to attacks for a bit. The shield attack would create a magical shield bubble around it to protect it completely from ranged attacks and it takes less damage from melee attacks, it also cannot attack while in this shield. There would be animations such as when it is readying a fireball, it will emit a small amount of sparks from its hands and then shoots a fireball. And same with the rest, it shows effects of that type around the wizologer. The soul attack could have a special animation where after it sacrifices other mobs, the souls fly around it and then fly into it. It would use these attacks at random and it would have an invisible cooldown time between the same attack and normal attacks, so it would not just use the same attack over and over again.
