How many Counterfeit Resin 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 18, roughly 7 clears of Il Dottore at 2.7 materials a clear, counting the Profaned Sprout and Twisted Withered Branch 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 Counterfeit Resin
Il Dottore, in Sumeru, drops Counterfeit Resin, Profaned Sprout and Twisted Withered Branch. Your first three weekly boss rewards each week cost 30 Original Resin and later ones 60. A spare Profaned Sprout or Twisted Withered Branch can be turned into Counterfeit Resin with Dream Solvent, 1 for 1, so a surplus from the same boss is never wasted.
Which weekly boss should you farm this week?
The Trounce Domain Recommender works it out from your own characters and inventory.
