(10%) 3 Wins: Silverstar (20%) 6 Wins: 2 Energy (30%) 9 Wins: 2 Enchanted Keys (40%) 12 Wins: 2-Star (50%) 16 Wins: 3 Fusion Stones (60%) 21 Wins: 2 Dark Prince Keys (80%) 26 Wins: 2 2-Stars (100%) 33 Wins: 3-Star (120%) 40 Wins: Fusion Boost Armor

I found this info from the KnD forums.

The stuff you get from each winstreak does not seem worth going to 40. I think this is just to give more points to those that spend gems in the arena every week and spread out the competition even more. 2 Keys at 9 is the only good one. I give 2 mil every week and get a boost w/o spending gems. Also i hate that they moved the 15 streak to 16, it's not that easy to get a 16 streak w/o gems. GREE, u have to make me WANT to spend gems, not hold onto them. I'm already facing a 3 line epic opponent almost every other battle, i miss a lot and they land crits non stop. NONE of this makes me wanna use gems or even spend time in the arena anymore

And yes I'm complaining, deal with it, this is the internet. Btw i like the quick enhancing, can't wait to see how it works on ios.
