How many Eroded Scale-Feather you need

Talent levels 7 and 8 take 1 each and levels 9 and 10 take 2 each: 6 per talent, 12 for Skill and Burst, 18 for all three. Taking every character above to 10/10/10 would take 54, roughly 20 clears of Lord of Eroded Primal Fire at 2.7 materials a clear, counting the Eroded Horn and Eroded Sunfire it also drops as converted with Dream Solvent (the same assumption the calculator makes).

Most players stop well short of that. The Trounce Domain Recommender reads your account export, subtracts what you already own and ranks all 14 weekly bosses by what you are actually short of.

Where to farm Eroded Scale-Feather

Lord of Eroded Primal Fire, in Liyue, drops Eroded Scale-Feather, Eroded Horn and Eroded Sunfire. Your first three weekly boss rewards each week cost 30 Original Resin and later ones 60. A spare Eroded Horn or Eroded Sunfire can be turned into Eroded Scale-Feather with Dream Solvent, 1 for 1, so a surplus from the same boss is never wasted.
