Bubble Floor


 

The dirt floor is irregularly shaped and covered in small mounds.

Mechanical Trap

Several small mounds cover the floor. Each mound is filled with flammable gas.

A DC 14 Wisdom (Perception) check detects the faint odor of gas.

A DC 14 Nature or Survival check determines that the gas is flammable.

The mounds can be avoided with a DC 12 Dexterity (Acrobatics) check each time a movement action is used. If it fails, then a mound is stepped upon and it releases the gas.

The gas ignites if there is any open flame within 10′. If it ignites, it deals 3d6 fire damage to all creatures within 10′. A successful DC 14 Dexterity saving throw reduces this damage by half.

The mounds can easily be bled of their stored gas and will not explode if there is no flame present. However, the mounds refill on their own in 1d12 + 12 hours.
