I was on the last dungeon of g2. Almost paladin

And then nexon decides to screw up and now we can't play atm.
Anyone wanna guesstimate how much longer we must wait?
Well in the meantime, I decided to get ready for the dungeon so...
Anyone have any tips for me on the last dungeon?
How to handle Tabhartas and Esras?
How to handle mobs of annoying gremlins?
Right now I currently have 50 bandages, a pet, 20 feathers
Total level=35
