Crispin has settled in nicely in Capstan, but one thing that bothers him is that his occupation as a cobbler is not really needed in the town. He’ll think about moving into Evermore and will only do it if you can develop 25 or more types of armor or accessories. While it says develop, it really just means make 25 pieces of armor/accessories. Note that they have to be 25 unique pieces and not just the same one over and over. Depending on the level of your Outfitters and the developments you’ve researched, you should have plenty of options available to you. Naturally, it would go quicker to craft the pieces which you have a lot of materials for first, then slowly work your way down to the others. If you can’t manage 25 pieces right now, you can always come back to it later. Once you’re finished, report back to Crispin to finish the quest.
