Spirit

The Spirit is one of the main characters of Crawl and can be controlled by a player or a bot. It appears as a Ghost that has hands that he waves around and a head that are attached to floating cloth that has the colour representing the Player.

The Spirit has the chance to become Monsters through use of Pentagrams and control whatever Monster it becomes, and controlling Traps by possessing them. Whichever Spirit strikes the final blow onto The Hero takes him over so that that player can begin playing as The Hero. If The Hero makes it to The Portal, the Spirit can become one of three parts of the Boss and attempt to kill The Hero so that he's warped back to the Portal with vey little health.

The Spirit can also collect Ectoplasm, which appear throughout the Dungeon. When enough Ectoplasm is collected it'll form a Follower. By using the B Button, you can use a Follower to form a Blob which becomes a NPC character who will attack The Hero until he kills them off, locking the doors in the process. The Spirit can also possess these Blobs by using the A Button whenever it's hovering over one and control them like any other Monster, even when the Spirit didn't originally summon that Blob. The Ectoplasm can also be used by Spirits to activate graves, which buffs the next Monster they call upon when using a Pentagram.
