this exam , i failed three times as an artist, then succeded really easily tho i am told this way no longer works but this is how i did it and in this order.
Itachi: duel life suiens swords , and demon wind.
hashi: weak to exotics , immuned to normal damage so break out the cow bell its over real quick.
madara: i went with normal weapons as hes immuned to spells , which i think is "exotic" damage
