Stagnant Water is a liquid that generates as pools in Lake Caverns in the Betweenlands, as well as at the bottom of the Wight Fortress. It acts mostly like Swamp Water, except when stepped in it will drain the player's Decay bar rapidly. It also provides a small amount of light.
- Beta 2.0.0: No longer uses a status effect to drain decay.
