That doesn't really justify why leave it up to RNG. You could just quadruple, quintuple, etc. You could also make it cost 15, 20, 25 of the current Coins that you get and that person would have to choose between upgrade items or the item they are seeking. Even if it did take 10 coins they would have enough tomes to buy the gear and thus eliminate the 'need' of having the item as you can buy the entire tome left side minus weapon in 8 weeks. Again the gear isn't even really bragging right worthy like the savage gear set is. Also if you set it at 15 weeks they would almost be entirely decked out in 340 gear minus the weapon.
