The Possessed

The The Possessed is an upcoming 1.3 enemy from the Solar Eclipse event. The possessed usually spawn singularly but can spawn in groups of up to eight but with most commonly five.

They start out slow, but they can collect momentum to charge at you, like the Wolf enemy. Unlike Wolves, these enemies can crawl on walls, similar to spiders like the Wall Creeper or Black Recluse. Whats different from that is that they can still "run" fast on walls as if it was walking.

Trivia

 * The Possessed is a reference to the 1973 movie The Exorcist.
