Writ vouchers can be used to buy special motifs, trait materials and crafting tables for your player home, among other unique items. Some of these items are tradeable, and can be found at guild traders throughout Tamriel, while others are account bound and you will need the writ vouchers to acquire them. When deciding what to spend vouchers on it is important to check the cost in vouchers compared to the cost at a guild trader for the same item.
These writ vouchers can be redeemed in the merchant store of Rolis Hlaalu, who you will also be turning in completed writs to, or Faustina Curio who is right next to him. These vendors can be found in your chosen factions capital city, usually near the crates that you turn completed writs into.
Master writs will have a number of writ vouchers you get for completing them based on the level of the writ. As you can see below, a lower level sealed blacksmithing writ might only get you 6 vouchers, where a higher level jewelry writ can get you hundreds. This number can be deceiving though, depending on what you are trying to acquire with the vouchers. For instance, if you want a normal crafting table for your player home, it will cost 35 writ vouchers, If you buy that crafting station from a guild trader, it will cost you on average 80-100K gold at the time this was written. Using the sealed blacksmithing writ below as an example, you can see that the cost to buy the materials to complete the writ is about 3,300 gold (this total is calculated with the help of the master merchant and writworthy addons on PC, if you don’t have addons you will need to calculate the cost manually). So, if you had 5 master writs, all comparable to this writ to total the 35 writs you would need to get a crafting table, it would cost you about 16,500 gold to craft them all and buy the table you wanted. Since this option would be less expensive than buying the table at the guild trader, it would be worth doing. On the other hand, let’s say you want to buy an attunable crafting station to place in your home to have a specific set available there for crafting.
Attunable stations cost 250 writ vouchers and typically run between 130-200K at guild traders. So looking at the jewelry writ below, you will get 578 writ vouchers, which will get you 2 attunable stations. This writ will cost about 400K for the materials. If instead you take that 400K and look for stations on the lower end, you could get 3 tables for the same price in gold. You can also sell master writs on guild traders, meaning you could spend the 400K you would have spent to complete the writ on 3 tables and sell the writ for a profit, making the total gold spent a little less. You will want to factor in not only cost of materials, but also whether you have the motif required for the writ when determining if it is worth the cost.
Please note that the above attunable crafting station prices were as written. The prices currently are very high for a station. They run from about 250 to 300k a station now. So you may want to reconsider certain methods when trying to obtain these until the prices get back to normal.
Master writs are given as a reward for completing normal daily writs, but you will need to be level 50 on a crafting line before they start dropping. The drop rate factors in the total number of traits you know in a profession as well as how many motifs you know. There is no definitive answer on how often you are likely to get a master writ, but reported chances indicate about a 10% drop rate on any given profession. This means you could do daily writs every day for a week and get no master writs, or you could get master writs every day.
