Completing daily crafting writs earns you coffers of a certain tier, denoted by the Roman numeral after the name (e.g. Woodworker’s Case III).
Investing skill points into the first passive in each crafting skill line will increase the tier of the coffer. For equipment writs, higher tiers raise the chance of getting a gold upgrade material (from about 3% at the bottom tier to 30% at the top tier).
All top-tier coffers also have the chance to reward Sealed Writs. It is (almost) always a good idea to earn the top-tier coffers. To increase the chance of Sealed Writs, learn traits. You can also fully learn some purple motif styles, but this can be expensive and it provides diminishing returns after the first few.
The main rewards from daily crafting writs are:
- Gold quality upgrade materials
- Sealed Writs (ideally with a gold-to-voucher ratio under 1000)
- Provisioning recipes

Other Benefits
Surveys
Doing daily crafting writs of any tier can occasionally reward crafting material surveys. (Note: The chance of getting a survey from coffers is not affected by invested skill points. It is flat 12.5% chance.) The gold value of harvesting a survey is extremely high compared to the time spent harvesting it. Addons, such as Map Pins, can help you find survey nodes easily. You can also do multiple of the same survey (in a stack) by harvesting everything, moving a certain distance away from the nodes, and returning to the area. The exact distance is different for each location, but it is much faster than traveling to each survey area one by one. The raw materials you get from surveys can be sold for a lot of gold or refined for the chance at getting valuable upgrade materials. If you are refining for yourself, be sure to slot the Meticulous Disassembly CP star (green tree) and invest points into the relevant crafting skill passive (Metal Extraction, Unraveling, Jewelry Extraction or Wood Extraction).
Gold
The gold reward for crafting writs can be up to 4,648 gold in total for all 7 writs. This is per character per day. It is scaled to your character level and can be increased with the Gilded Fingers CP passive in the green tree.
