Why exactly do u need high dex for it? And yes,it is the whole point of going into shinobi. Pierce debuff + kunai and clones is the burst
Well, to sustain Bushin, youâll require DEX. The cloneâs HP is reliant on your DEX, and my DEX is 8.
I see, I havenât used my stat reset yet and neither did I decide what class I want lol, if cathexis replies tag me pls 
if ya like corsair then i think
swordsman >peltasta > hoplite 2 >corsair 3 > shinobi
would be nice, but shinobi advancement quest is a pain
