Hi, I would like to suggest reworking items by setting max item lvl to 30 and removing required level on items.
Balance might include something like this
-Feather cost between lvl 20 and 25 = 5 instead of 3
-Feather cost between lvl 25 and 30 = 7 instead of 3
In this scenario person would have needed 924 feathers (if my math is correct) which would be achievable in 58 weeks (if we get avg 16 feathers/week)
