Talk:RR3 Wiki:Upgrades Strategy For 100% Completion/@comment-28328990-20160528181214/@comment-25956839-20160528192427

The bottleneck currency is, all tiers and 84% completion of AWD Attack can be reached without upgrades. Only the last 100% reward of 21 can be won, with upgrades costing 175, therefore the reward for completing AWD Attack is 175 - 21 = 154.
