Evil Hole (Unused)

Evil Hole are unused Objects. They spawn a limited number of Fallen and then disappear. They don't have a special animation for spawning, fallen just appear near them. They work perfectly when enabled but can't spawn anything else than fallen. There even is an Pandemonium Event version called Demon Hole: it would spawn these all immune Pit Lords, but it spawns Fallen anyway.

There are projectile graphics in the game files which look the same as Evil Hole monster. Their animations are called for example: "smithholeneutral" which means that The Smith was supposed to summon Evil Holes.
