Info: (made by me) / They dont carry swamp fever but drains your stamina along your health. Make sure to get rid of em by using a cooking pot or campire (recommend campfire its easy to craft)
Deseased Leech (A red leech)
Info: They carry swamp fever so be carefull seing this variant. To cure the swamp fever use lesser antidote if you dont have.. you have no choice but to you nameless venom nameless venom can be dropped by nameless (his name is just nameless)
Drops (both variants): Raw meat, Hide (i think) and leech blood. (Deaseased leeches drop more leech blood.)
Uses of leech blood: Fishing (can attract pirana’s saber tooths’s and normal fish so highly reccomended for fishing. Amber is used too)
I know a good trick for raiding find a disease that leech let it infect one of your dinos with mega rabies then kill the leech and make sure you brought lesser antidote then after it infected your Dino take the dino put it in a cryopod then take a flying Dino then drop a ton of them and throw them in the enemy's base and wait once it's done its job then you can raid the Base please help so people know about the mega rabies
They Can indeed be tamed, however they are awkward pets to keep as they move so slowly in land. If you deploy a fish basket, you can capture them as tames. Perhaps if you caught a diseased one, then you could use it to infect other players, causing endless suffering.
