How many Lightless Silk String 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 72, roughly 27 clears of All-Devouring Narwhal at 2.7 materials a clear, counting the Lightless Eye of the Maelstrom and Lightless Mass 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 Lightless Silk String
All-Devouring Narwhal, in Fontaine, drops Lightless Silk String, Lightless Eye of the Maelstrom and Lightless Mass. Your first three weekly boss rewards each week cost 30 Original Resin and later ones 60. A spare Lightless Eye of the Maelstrom or Lightless Mass can be turned into Lightless Silk String 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.
