So.. yeah. I have a bit of a complaint about this fight, and I also may need some feedback, because this [censored] is just ...awful.
First Run: Walk in with Quelaag's Furysword+5. Not too difficult at first, but by the time I have the first king at HALF health, boom. Another one spawns. By the time I have ONE dead, there are 2 more. This cycle repeats.
Second Run: Thinking it was just a run of bad luck or poor strategy on my part, I go in again with the same weapon, and I'm more akeen to my dodge rolling in order to avoid the blade. Regardless, I still die due to the same problem I had previously.
Third Run: So now I think it's the swords fault.. even though UNLESS Four Kings are resistant to Fire, then there is no reason that it should be a bad weapon. I switch to my Lightning Uchigatana+5, and run in. It does more damage per swing, but it's slower; therefore the DPS doesn't balance itself out. I die once again, due to the same problems mentioned above.
Fourth Run: Same thing as second run, just with my Lightning Uchigatana+5. I also make an attempt to equip my Crystal Halberd+5 (brand new; repaired) and cast Magic Weapon on it. Still nothing.
*So now the question is, what am I doing wrong? I've made numerous attempts with half-decent or REALLY good weapons, and yet they continously rock my [censored] up. If anyone could pass along some advice, I would greatly appreciate it.
