If it hits you with its arms, you'll go flying high.

A few things you needs to be careful off: You can slag Terra, so use that your advantage. Hit the yellow 'orbs' to deal critical damage. If you deal enough damage quickly enough, he won't hit you and just keep going back in the ground and pop out again. He will come out of the ground and occasionally go back in. Once you get to the Terramorphous peak, you'll have to drop down and use the horn. To get to his peak, you'll need to have 4 Eridium with you. If you need better gear, try the Trading Thread. Only the Host will obtain the trophy if you decide to do so. If you're having trouble with Terramorphous and don't have any friends to battle him with, you can always try the Co-Op Partners Thread. It's possible to solo him, more on that later. Terramorphous is a raid boss, so in theory, you'll have to defeat it with multiple persons. Terramorphous in Playthrough 2 has more health. However, when starting Playthrough 2, this mission will disappear, so you’ll either have to finish playthrough 2, or you can also go back to playthrough 1 when you’ve leveled up to 50 and start the side mission there. You’ll have to start Playthrough 2 first and level up to level 50 to even have a chance against Terramorphous. But as you can see, the required level is level 50. This mission requires you to kill Terramorphous. (Look for the ‘!’.) She will give you the mission ‘You. Once you’ve completed your first playthrough, go back to the Sanctuary and a new side missions has appeared at Tannis at the Crimson HQ.
