Professional Kobold
The first room of the death snare hits you with fatigue and suppressed sword, the second is full of guys who cast silence, the third has an acid damage floor that disrupts casting and causes a lot of dmg each round. The last one is a poison floor that drains con and acts like a fog cloud and has you up against a much of mind flayers and snakemen using bleed/blinding weapons, but because this is far too easy a demon lord gets summoned in the middle of the room after a few rounds.
