Goddamn the optional bosses are really goddamned hard. I have a Knowledge Book and all new weapons/armor (lvl30+ weapons with 4-God and 4-Heaven, some also with Follow-Up or whatever, and similar armor but not as good properties), and the FIRST boss at Ends of the Earth wreck me. I managed to get off a Double Draw II with Knowledge Book at the end of the chain, only to have the asshole heal for TWENTY EIGHT THOUSAND DAMAGE. Between that, the stupid strength-sapping environment that cuts HP in half, the awful "you're taking too long" mystical events that seem to double the boss's attack/defense/whatever, AND the constant speed increases that eventually allow the boss to perform five or six attacks in a row before you can do anything else, this dungeon isn't goddamned fucking around. Easily harder than everything in Ayesha, and then some. I... I don't really know what to do now. I guess I'll hit up the Fallen Ruins and hope the (likely) boss waiting there isn't nearly so hard.
