This dungeon was a bit of an aggravation. The longer we remained in the dungeon the more apparent it became that bringing an MM wasn’t the best idea. There were bodies to be used but the enemy MM’s would quickly use those available. In normal mode where our hero beat out the monsters on cast times, it worked well but in hard mode I would suggest you opt for some corpse control (putrid explosion, wells, etc) instead of an MM.
You may also want to bring Frozen Soils. The stone summit here can resurrect and can be taken down more quickly if you bring Frozen Soil. If you decide to bring Frozen Soil, be very careful about when and where to place it. My advice is if you have a ranger in your party then look at Frozen Soil and if you don’t it may be a waste of a secondary. The spirit is definitely not as valuable here as in places like Slaver’s Exile.
