Way too much. Just eying it with the improvements to the system(1 guaranteed fortune coin per spin) at 15 points a frag was no more than 6k as an educated guess when I saw it this morning. 190 coup 10 blessing gives you 10 free fortune coins. Also you would have to factor in the prizes for a point threshold and free dew drops.

After buying it I actually overshot it by 1500+ coups or ingots seeing how it only ran me 4.5k. Most people have got it under 5k. I would recommend the clothing since it gives about a 2k power boost and is much more cost effective and beneficial for all your current ninjas than a ninja you may or may not use long term. Granted my hanzo is in my ranked lineup but that is all I ever use him for. You can actually feel the difference in the damage boost as well if that helps you make your decision.
