you can see the drunkmath so hard in the first floor boss, taking 30+ damage at 7 prot but 1 at 9, despite the multipliers putting you at 3x. you could say its .. FOOLISHNESS
he cant get all 6 slots there + he is fatal to blunt and hair coupons gets +100% dmg iirc which makes him take the normal damage even if he has 10 protection. with ego gifts he might get a chance but the actual fight doesnt allow him
I dont think its possible without level 45 (UT4 is not important) the start of the run is the hardest part, you take too much damage and if your level is 30 you have literally 15 levels lower than me which means lower clash power and defense level which makes you take more damage and less offense level which lowers the power of your counter, I had problems trying to solo the first floor with only using foolishness myself, I had to restart for good event encounters to get good ego gifts. its a hard run, very good rng is needed and you have to pick your floor themes smart
