You can max all stats, it's for the best, for the action bar the INT (more crit dmg?) stat makes the central red area wider, DEX (more def?) makes the arrow move slower and STR (more dmg) make the yellow/orange sides biggerWhat stat do I need for final fight ? boss just make me cum and 1 shot me. the dungeon was tedious as hell with no save before boss.
Also, you need to catch the real boss, the one that is breathing (has a slight animation movement compared to the other dolls) the boss will try to attack you if you click on her instead of raping you like the other dolls. So only the fake ones make you cum, the real one wants to actually kill you.
