Strategy
The infamous gimmicky enemy of the collab, they are actually more annoying than threatening. Since only pleasure attacks work on Nightmares your options to deal with her are extremely limited. You have to keep most of your active party with members able to dish out pleasure damage, as you will simply be forced to flee otherwise.

At an equal level, they have extremely low HP compared to other enemies. If you have a great party member to deal pleasure damage, focus on them first as they will fall extremely fast.
