hes mystery is skill is op dealing critcal means much plus he does critical damage with 1.5x damage

this means he does criticl damage with increased power of 50 % but....if ugive him buffs like increasing ninjutsu 40% it will increase damage in different method 1.5x1.4=2.1 so instead of getting 1.9 he gets 2.1 if u give him 110 nin buff he gets 1.5x2.1=3.15 buff so instead of getting 160 more damage on mystery he gets 215% more
