+1 hide armor that completely covers and adjusts to fit.
DM notes. Unless you use identify or legend lore, you won't realize this is a Skum Suit. It will fill with water and can only be removed underwater or by a remove curse. For a skum it protects their skin from drying out. For aquatic creatures it will even serve as a spacesuit.

152. The Pit That Knows You Didn't Put A Point In Swim
-- A 20x20 section of floor collapses, and down you go: 50' drop to the water, which is 100' deep. The walls of the pit are vertical and slippery. Hungry monsters optional.
Neither the trap nor the pit are magical. (The hungry monsters might be.)
