Unfortunately, Megalanía is not in Ark Mobile... lìke so people can see!

Every bite will give you a disease that lasts for 80 seconds called Mega Rabies. It's contagious, rapidly drains your health and stamina, and also curable if you have lesser antidotes or wyvern milk.

Kill it.

You find these boys near the volcano on ragnarok, just spawn in highlands E and you will spawn on a beach with a bunch of random stuff and some megalanias wandering around.

Bring antidotes. Like 5 of it. Tranq it fast and run.
