The XIV encounter recipe in a nutshell

[Absurdity]

The first boss in Strayborough, or rather being chased by a thing with wonky hitboxes that you shouldn't get hit by, isn't even really new, it's basically a variation of E8S Light Rampant orbs.

The spinning ghosts on the 2nd boss are a more interesting mechanic that can be built upon for higher difficulties imo, although I'm not entirely sure if that hasn't been done before either.
