Really good at abberation, they gave you charged buff against nameless, protect you from radiation(immunity), in exchange they suck off your blood and rare chance of giving you diseases. Buff last for 600 seconds. Awesome way to go into radiation zone to get rockdrake egg or red gem without the need to make yourself a hazard suit in the mid game.up this so people know

Stand over a fire if a leech is On you. If it gets on your tame go up to it their should be a hand click the hand and the leech will disappear

They protect you from radiation so you can get red gems for gas a collector
