I'm currently running a sort of mega-dungeon made of other dungeons cobbled together. I know most of my players browse here frequently so I'll keep the description brief.
At the end of the current section of the dungeon there is a large weakened section of the floor. The floor will crumble, dropping them (harmlessly) deeper into the dungeon.
Does it remove player agency to skip asking for a check when the floor begins crumbling and have them drop through, as the dungeon requires? If it does remove agency, what alternative approaches are available?
I generally don't take away player agency like this and our group is likely fairly new to D&D compared to most people here.
