What if the soul of an aboleth or a beholder got trapped inside you? The Vessel is a half-caster class that answers this very question. When you become a Vessel, your body is now host to the soul of a powerful entity that is slowly corrupting it. Featuring a brand-new spellcasting method, Corrupt Spellcasting, where prepared spells can only be cast once, then they become corrupted and cannot be cast again until this corruption is removed through a short or long rest. When all your spells become corrupted, your own soul begins to fade, and you score critical hits more often as this bestial nature emerges, but hostile creatures can do the same to you! Also, gain powers based on your chosen subclass (which is dictated by the type of creature locked inside you) that you can use indefinitely, as long as you have the charges! As you gain levels, you start to become more and more like a 5E monster – you gain legendary resistances, legendary actions, and even a Mythic trait. Will you master the darkness within?
