An Underdark cavern with a thundering waterfall and a deadly ambush.

Ambush Point

The high ledge that runs behind the waterfall (40ft from ground) makes for an excellent ambush point for enemies, although add a +5 cover bonus to the target’s AC if attacking through the waterfall.

A secret door in exit 1 leads to a set of stairs carved into the rock, which can be detected with a DC 15 Perception check. The stairs are completely obscured from the ground.

Waterfall

Water falls from a crevice in the cavern ceiling into a 30ft plunge pool, which connects to a fast-flowing stream (5ft deep) leading out via exit 3. Characters wishing to swim or wade through this water must succeed on a DC 15 Swim (Athletics, DEX) check or be pushed.

Stalagmites

Surrounding the stream are a series of 5ft stalagmites. Players or ambushers can hide behind these stalagmites for total cover.
