My question once you use a key can you keep refreshing till you get sage naruto, or is there a limited amount of refreshes, and does refreshing cost anything.

LOL the event is rigged, I tried just to see what the rate is for naruto frags, and after 1.3k worth of ingots/coupons, got a grand total of 2 sage naruto frags... Better off waiting till the lvl 70 pulls, this is ridiculous...Refreshing rewards requires a sage key at 10 cpn/ingots yea... no ty

I would have been glad to put money into the Sage Treasure event if the Naruto Sage Frags actually were a thing you could roll/refresh with the keys, but its literally one of the random rewards you get from using a key, not something you can just straight away purchase...Guess i'll buy a few scroll packs and save them for when I hit 70.
