holy shit that end boss is nuts. i certainly shouldn't have gone to it at lv160, with pretty shit luck encounters at that. and why the heck is lust builds are so broken. i literally fucked the boss with 377 rp heals to death... eventually... it took a while, but i only had 50 for the stat.
Problem is. My chara dies faster than it happens seems.
max guard. seriously. you will need at least 12 by floor 100. after i started always getting faith to 70 first it became easy to survive till lv100. though stacking even more of it doesn't hurt. fists imo are garbage, all cards extremely expensive. kicks are nice, 3-4 kicks in the deck and get a rare one that transforms all of them into chaining kicks basically. lust is most powerful, since with high defence you get a ton of time to stack it, but getting lewd cards from the orgy is preferable, they pin enemies, which forces them into fucking you, and with Relief and high RP base regen you never cum, so never lose defense. magic is whatever, good luck getting any of those without luck bonuses. heal is worse than respite by a long shot, having 22/22 regen in battle(without that risky 1hp achievment) is broken, since most enemies don't attack constantly(and those that do you can pin down). If you will go for lust double lust gain blessing is very good, and a succubus deck too, though i seem to never roll those at once. I can't even roll beastification and double gain at least, and reroll animation is so painfully slow(and CE speedhack dopesn't work on it) i can't be bothered to minmax the rolls.
Also, don't forget that this is a deck building game. Sometimes you're better off not taking any cards at all if they give you no synergy or ruin the existing ones
