Easily killable with a wyvern. Lightning and poison easiest down to longer range in attack. Just hover above and light it up :) killed my first today and it didn't touch me once. Just remember to watch stamina ;)
If you really want to kill one of these things, just life it out to water. MAKE SURE IT IS FULLY SUBMERGED OTHERWISE IT CAN STILL KILL YOU. If you have scuba gear and a good sword, it really helps. Then, because it can’t attack underwater, just keep swiping it with your sword. Bam. Easy xp
The fastest way for your entire tribe to rage quit is to have one of these randomly spawn in the center of your base. Oh, that doesn't happen? Think again, literally just did. What the actual f*** Ark??!!!
Pls do not take their eggs and at first I thought the egg was from something else because I was new to the game and I tuned around and it f*cking killed me in one hit little did I know and I learned to avoid that very soon
