How many Shard of a Foul Legacy 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 Childe at 2.7 materials a clear, counting the Shadow of the Warrior and Tusk of Monoceros Caeli 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 Shard of a Foul Legacy
Childe, in Liyue, drops Shard of a Foul Legacy, Shadow of the Warrior and Tusk of Monoceros Caeli. Your first three weekly boss rewards each week cost 30 Original Resin and later ones 60. A spare Shadow of the Warrior or Tusk of Monoceros Caeli can be turned into Shard of a Foul Legacy 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.
