If you're spending 10k Ingots and get 11 shurikens everyday, you have a small chance of getting it but not guaranteed.

Worst scenario (10k): 24 Frags,

Best scenario (10k): 27.99 (Possible if you get the daily shurikens)

For a 100% Chance of getting him, you'll need to get 11670 Ingots (Not factoring daily shurikens)
