White Dragon Pool Trap
This room is freezing. Instead of acid, the pool is filled with water covered with a sheet of ice. No stone wheels are present.
If the total weight on the ice exceeds 300 pounds (for instance, if two Medium creatures or one Large creature moves onto the ice), the ice breaks. A creature that falls in the icy water triggers a Failure.
Pool. The ice is cloudy, but not so much that it obscures the enameled tiles that line the bottom of the pool, which are painted with white dragon heads. An Investigation, Nature, or Perception check, or testing the ice, reveals that it is weak and may collapse under heavy weight.
- This is a magical effect created by transmutation magic. Casting dispel magic on the ice requires a spellcasting ability check and causes the ice to melt, disabling the trap.
- Cold damage dealt to the pool thickens the ice, allowing it to support an additional pound for each point of cold damage dealt. Fire damage weakens the ice by one pound per point of fire damage dealt.
