while it is a good game i feel it's too unbalanced (but what can you expect from a hentai game)
any build that is not DoT sucks, like armor/charge/focus/combo
-best build by far is just stacking bleed+burn by discarding two cards on the first battle ASAP. and put 6bleed+6burn+max discard effect on them so you only need one discard to be maximized.
-use rest with surplus and cleanse debuff. it's key before high cost cards.
-use the card that gives random dots with surplus and replicant and max mod OR burn. it costs 4 crystals so use after rest.
-stack DoT by throwing stone with max surplus + charge UP, if you get an enchant that reduces throw stone's crystal mod it's gg anything. the charge up is good on throw stone since you could get 3 in a row for...
-run tiger slash with splash. if you get charge ups from stone, you can use this card as a dispenser that will OHK all small mobs, first priority discard against bosses.
-after stacking dots on one enemy, use the card that spreads dots to all enemies with max surplus + max initial mod. it will exponentially scale your dots, you can get around 3k dot procs on everyone.
-use pyrokinesis (the card that augments burn stacks+more damage the more you burn) with max surplus and splash. it's a secondary way of dealing with mobs, while also fortifying your dot build up. if you can lower it's crystal cost it's even better.
-finish with the card that deals more dmg the more dots you have, with replicant and max mod. it will cost a whopping 8 crystals to use, but you use it after a rest card and it can deal upwards of 5k dmg.
final card list should look like
-rest with surplus, lowered cost not mandatory but welcome.
-throw stone (dot stacker+charge stacker)
-burn on discard(discard/max effect on first battle) 6bleed+6burn
-bleed on discard(discard/max effect on first battle) 6bleed+6burn
-spread dots (with surplus, and alternate between targets to exponentially increase Dot stacks) 6burn+1initial mod
-inflict random dots (with replicant, use after rest 99% of the time)
-multiply burn stacks (with surplus)
-deal dmg the more dots you have (with replicant, boss killer card, use after rest)
-tiger slash with splash (make use of throw stone's charges)
-paralysis (good CC to get early discards and borrow time to stack dots) with 6bleed+6burn
good items to aim for in the dungeon:
-faster bleed/burn stacks
-slower decay of dots
-damage from charge stacks
that's it.
now look at funny final boss getting 2k burn stacks +500 bleed + 200 poison, after you spread the dots from her sister to her.
