Questions

Which weekly boss should I farm in Genshin?

The one whose materials you are shortest of for the characters you are actually building. The Trounce Domain Recommender works that out from your account export.

How many weekly boss materials does a character need?

6 per talent from level 6 to 10, so 12 for Skill and Burst and 18 for all three talents. Each character uses exactly one weekly boss material.

Can I convert weekly boss materials?

Yes, within the same boss: Dream Solvent turns one of a boss's three talent materials into another of the same boss's, 1 for 1. You cannot convert between bosses.
