Daily Material Farming Schedule

Domain of Mastery (drops Talent Books) and Domain of Forgery (drops weapon ascension materials) don't stay open around the clock. Each Domain is tied to a fixed cluster of weekdays, usually grouped in pairs:

• Monday / Thursday / Sunday
• Tuesday / Friday / Sunday
• Wednesday / Saturday / Sunday

In other words, any given Domain only comes back around on 2 specific weekdays (besides Sunday) — if it's Tuesday and you need the books or ore from the Wednesday group, that Domain isn't open yet and you'll have to wait for its day or wait for Sunday. Sunday is the one day every single Domain of this kind opens at once, which makes it the best time to batch-farm several characters or weapons that normally fall on different weekday groups.

Every run of a Domain of Mastery or Domain of Forgery costs Original Resin, and only the first clear of the day rewards materials — any further clears of the same Domain that day won't hand out extra materials. The cutoff for what counts as the "first clear of the day" is 04:00 server time — so clearing a Domain at 03:50 and clearing it again at 04:10 counts as two separate days, each paying out the full reward.

Since Original Resin is a limited resource, the sensible move is to prioritize the Domain of whichever character or weapon you need most urgently on its open day, rather than clearing every open Domain regardless of whether it feeds the build you're actually working on.

The day-by-day list on this page shows exactly which Domains are open on a given day and the material sets they pay out — click any material to see which characters or weapons need it for Talents or ascension. Since a single character needs all 3 tiers of Talent Book (Teachings, Guide, Philosophies) from the same Domain of Mastery to push a skill to its higher levels, if the Domain you need isn't open today the sensible move is to switch to a different upgrade for that character (elemental-gem or regional-specialty Ascension) or work on another character whose Domain is open today, rather than letting Resin go to waste.

Since each 3-day cluster (2 regular weekdays plus Sunday) maps to one fixed set of Domain of Mastery and Domain of Forgery, the most efficient approach is to plan out 2-3 priority characters or weapons in advance and remember which weekday group their Domain falls under, instead of opening the game each day and deciding on the spot. On the day a needed Domain is open, spend your available Original Resin on the first clear (the only one that pays materials) before spending it on anything else like Mora or EXP farming.

For players still climbing early progression, it makes sense to target the core carries of the main team first, then branch out to supporting characters once their Domain lands on a day with Resin to spare.
