Do you have haste spores? They're crazy powerful for this fight. Controlling a point here is easier than with the Minotaur's, Bulette, or Phase Spiders.You get them from Spaw. First, destroy the 2 ladders, closest to the gith, up to the bridge. Spread out your characters on the bridge, toss your haste spores. The flaming sphere makes a good distraction before your first attack. Keeping a couple potions of hill giant strength might be a good idea, if you get swarmed and need to toss some Gith off the bridge, but I didn't need them. I decided to challenge myself, and beat it with lvl 3 characters, the only equipment I'm wearing that isn't base is the headband of twisted intellect.
