Not looking for easy street..

I guess it has been about a month since someone complained about this one. We were probly due.

OP - Aside from using hide and firing off the gunblade(the screenshot Milkie provided), you really only need to do a couple things to win. You need to keep attacking, you need to dodge, and you need to keep your health up. Before you even start the fight, drink the potion thancred has. Look at how much it heals, and how long until you can use it again. During the fight, anytime you are down a little more health then the potion will heal take a drink(so for instance if the potion heals 35k, being 40k hurt is a fine time to drink). If it gets sticky and the potion isnt quite ready, put yourself at medium range and just run out of attacks until the potion is usable again. Medium range gives you enough room to dodge everything, but still get in close if he does his donut attack(long range paradoxically makes dodging a couple of the attacks harder if they are aimed in a bad way). Dodging his various aoes is priority number one. If you dont, the damage adds up too quickly. Your attack combo will heal and shield you, so you effectively have more hp then it looks like.

Then after

the second time you fire the gunblade, Ranjit becomes wise to your tricks. He immediately foils your next one or two invis attempts, and he steps up the attack. Meanwhile, you are suffering the after-affects of the invis trick. This plays out as you being staggered. You periodically stop moving/attacking/etc for a second while stunned. This makes it all the more important that youve been keeping your hp high, and use your potion as well as you can. After a round or two of this, you get a new invis option that still fools Ranjit, and your last cartridge ends the fight as long as you hit with it.

But again, dodging and attacking plus keeping your hp in good shape is the entirety of the fight outside of the gimmick that you claim already to know. Perfectly doable on controller or keyboard/mouse, perfectly doable on every difficulty level... there is nothing that should stop anyone from winning this fight.
