I completed True Vault Hunter mode and hit level 50 a few days ago, so I went back in today for some achievement cleanup. A friend gave me a Grounded The Bee shield a while ago and I had been keeping it in my bank for when I finally hit 50 and was prepared to square off against Terramorphous. The Bee didn't disappoint.
After trying a few times to just go head to head against Terramorphous, I went and hid behind the rocks and picked away at him with my shotgun that does about 4900x14 damage. With The Bee amp, that works out to over 865k of damage per shot, not accounting for criticals. It took less than a minute to beat him this way. If anybody hasn't beaten Terramorphous, get to level 50 and find a Bee shield quick and get it done before the nerf comes.
