Use leader allosauruses. Make the Titan bleed and run away once the debuff stops, run back and attack it, from the back and prepare for a quick getaway! Might kill one or two allosauruses if you’re not careful, you can pump at least 1500 hp and have a lot of meat in the inventory for quick healing. Run a fair distance before healing as it might come and kill you while you’re healing and well... rip your allo and you
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??!!!
