I'm getting to the end of floor 9, and I keep facing S & B. I get WRECKED with a Frosty Friend/Lightning Cloud/Flamethrower build. Arguably, I could shift Lightning Cloud to something else since I spend 95% of S & B running away from something, but still. It's ridiculous. I still have yet to clear The Red King quest because there's only ONE way to do it, and I find that reprehensibly lame. There should NEVER be *ONLY* one way to do something. Pigeonholing builds a la Blade And Soul achievement strategies is just sad.
I'm nowhere NEAR G-Meister's skill level, but like I said. I manage to get to the end of floor nine with between 3 and 5 health potions, various dmg/skill boost potions, and full health. I STILL have yet to kill EITHER boss before getting killed. Something is awry. Either the Lightning Cloud needs to distance itself more to hit stuff while you're trying to keep your distance, or the FF needs to not get absolutely demolished by the S & B Snow pellet storm, or something. I don't know. This is just my personal build, and my personal experiences.
And this build has absolutely NO chance against The Red King. =(.
