Presence

Presence is one of four bosses that can appear within the Archives. There is also a basic enemy called an Insubstantial, which looks exactly like Presence but is much less powerful. It can spawn and attack the player at random as an effect of a Curse of Paranoia, and appears in some rooms on floor 6 and below.

Hard Mode
Presence features two unique attacks in its Hard mode variant, outside of some slight alterations to its existing attacks. The two unique attacks can occur immediately after its initial burst that would normally lead into five subsequent bursts.
