Heya bro, you're supposed to let the snek swallow you THEN interupt him

The team I used that was very effective was

x-x-Neji
x-x-Kimimaro
x-MC-Hinata

neji round one will taunt orochi
round two neji will interupt orochi and hinata will taunt
round three kimi will evade orochi and take a hit
If oro's not down by round 5 you're doing it wrong

Interupt every Manda bite, and let him swallow you. Interupting him while you're in his stomach gives you a free turn of damage.

Yessir Azure fang is the way to go.

honestly you just have to survive. he only bites more than once if he kills something, typically a clone. Dont use clones on this exam EVER
