Water Leech

Water Leech is a Sewers and Rift enemy that is lethally mobile in water but nearly helpless on land. While in water it dashes in a straight line with infinite range, passing through units and draining health via lifesteal. Out of water its speed drops to 1 and it seeks the nearest water tile to reposition. Removing all water from the stage renders it essentially harmless, making terrain manipulation the most reliable counter strategy.
