Shadowheart is an adept cleric, and figured that her illusion magic could handle any simple monsters that might be lurking in this sunken temple. She's been through some pretty rough stuff- what could possibly threaten her in here?
Well, oozes, it turns out. The acolyte of Shar wasn't expecting mindless enemies that could pose an actual threat. With complete immunity to illusions and mind altering magic, there wasn't much she could do but try to fight them directly. Ok, fine, she's no stranger to straightforward combat. It's just two slimes.
They sure didn't fight as mindlessly as she thought!
