Maybe the upgrade system should be changed to coins, but ten coins is too little. A weapon as op as Champion Mercenary shouldn't be able to be upgraded all the way to level 17 with 80 coins.

Ok, how about this? The upgrade cost per level would be depending on how many upgrades there are. The shorter upgrade path, the higher. And the rarer, the more costy it would be.
