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 ;)
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??!!!
Can be killed with 2 high lvl gigas mate boosted. Our 2 highest gigas have 225% dmg and melt titans in about a minute. Official server.
Just stay away from the back leg stomp as it can enrage a giga quickly due to speed of attack.
