Borderlands 2 Tiny Tina's Assault On Dragon's Keep Walkthrough Part 8 – Dwarven Allies: Greedtooth

Head to the South, out of Ore Processing then break off to the East when you can. There is a pair of Rock golems blocking your way forward. Fight on through them and get through the door. Head on forward and drop down to the level below. You will find Greedtooth on the far side of a river of molten lava. He will taunt you then jump into the lava. Tina will also point out the weird magic globe that sits to the right of his throne. He will emerge from the lava as a massive Golem. Your goal right now is to simply survive a while and blast him as much as you can. If you need a damage boost, in the South Greedtooth attacks much like the other golems with a smash attack and throwing his fists at you.

Once you gotten him down a quarter of his health he will jump back across the river of lava. At this point some Dwarves will show up both by Greethtooth and around you. Ignore the Dwarves by you so you can save them for when you need a Second Wind. Just keep firing on Greedtooth until you can get some clear shots as the Weird-Ass Magic Globe. Shoot at it immediately and inflict what damage you can. During this time Greedtooth will likely start shooting his Laser Eyes at you. Get behind cover to avoid the worst of what they can do. If the dwarves in the area are doing notable damage, now is the time to thin the herd. Otherwise just focus on the Weird Magic Glob and smash it. This will break the curse on Greedtooth.

Greedtooth will thank you for breaking the curse on him. It seems like things will go well then Brick's desire to punch the Great Emancipator catches up with the party again. Greedtooth will came at you once more but whatever damage was done will carry over to this fight.

The big addition seems to be a blue shield that will sometimes cover Greedtooth inside the Golem. Blast it a few times and it will break. After that just keep shooting at him. He will stay in the main area for quite a while, until his health is down to a quarter or less, then jump to the throne again. Once again you need to shoot him at a distance while his minions throw axes at you and he bombards you with his laser eyes. Kill him then head across the stairs that rise up out the lava. Go over to the marker where Greedtooth's corpse lay to collect the final dwarven letter. Be sure to also hit up the Dice Chest for a chance at some nice loot. After that head into the portals that Tina makes since Lilith (rightly) complains about having to walk back to Claptrap.

After going through the portal the letters are fully revealed: “R”, “A”, “T”, “F”. Put the letter in, left to right, to spell out “Raft” then hit the button in the middle. The door will not open. After that Mordecai will figure it out: “Fart”. Spell that out and hit the button to open the door. The door will open after that and clear the way to the next chapter.
