hey!
regarding the guys in ffa: gonna change this as soon as possible, thx for reporting, hp bars system is really old and needs a lot of refactoring
for the irregular part: thats some ol knowledge surprised you looked into that, it was planned to have 11 balls but one of them got deleted
scythe/unarmed are the easiest one theres, you can slap almost any scaling card in existence and try to win
grimoire is a more tricky question.
getting unarmed factory card as soon as possible helps a lot, opting for the pacifist build as well (full healing & dmg reduction)
wish you the best and thx for playing ball game <3
