Etch a scroll on that load-bearing pillar and you don't even need dispel.

Prepared defenses with ice slick or grease are definitely a thing that I use.

The players were also particularly frustrated with the room that got hotter as they stayed in it, defended by orichalcum golems (although the payday from the scrap from that fight turned frowns around).

Golem in general is pretty abusable, even if you restrict it to thematically construct traits. I like golem mechanical artillery myself.

They also didn't like the room that was the site of a mass suicide and full of a couple hundred ordinarily deceased skeletons. At first they were suspicious, but because it was the entrance to the dungeon, they eventually stopped caring about it, until the opposed adventuring party's necromancer cast Mass Zombie while the PCs were in the dungeon. She instructed them to remain in place until the PCs were halfway through the room.
