This cultist enemy seems like a very interesting concept, not gonna lie. And it pairs really well with idols in separate rooms. Although, it is pretty much a Sentry with wallhacks, lol.
The Cultist is cool but it's pretty much just a grounded Virtue. I appreciate the effort that went into it and find the art design to be awesome, but i don't see how it would be used differently to a virtue in most circumstances. Hopefully the creators keep making enemies and get even more creative with them in the future
