How many Elixir of the Heretic 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 36, roughly 14 clears of The Doctor at 2.7 materials a clear, counting the Madman's Restraint and Mask of the Virtuous Doctor 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 Elixir of the Heretic
The Doctor, in Nod-Krai, drops Elixir of the Heretic, Madman's Restraint and Mask of the Virtuous Doctor. Your first three weekly boss rewards each week cost 30 Original Resin and later ones 60. A spare Madman's Restraint or Mask of the Virtuous Doctor can be turned into Elixir of the Heretic 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.

From The Doctor, the weekly boss in the False Moon Institute domain (Nod-Krai). Each clear drops 2 to 3 of its talent materials, a mix of Elixir of the Heretic, Madman's Restraint and Mask of the Virtuous Doctor, and Dream Solvent converts between the three 1 for 1.
