chances of geting 40 kashi fragments with the ammount you can spend are very slim.

Overall kashi deals above average damage with his mystery, and this further increasse if the enemy is not konoha unit. But he shares same weaknes as any other kashi versions, which is him being very fragile ninja. Apart from all of that his shadow cloak passive can be very handy, Works really well with light main, shisui and itachi. (not necesarily all at the same team)
