MINI-FAQ

What do these things do, anyway?
Having one of these keyitems lets you craft recipes that wouldn't be otherwise available. There are new recipes available from the Sept 13 patch that require having one of these keyitems to craft them. Once you have a Guild Point keyitem you can use it to make as many recipes as you like; it is a tool that unlocks new recipes, not an ingredient. You can get as many different Guild Point keyitems as you like, if you acquire enough Guild Points. Of course, you can only be commissioned with one guild at a time to gain and spend points, so this will take a while.

Ooh, new recipes? Like what?
The cooking guild has a bundle of new sushi recipes that all require Raw Fish Handling. Alchemy has a lot of new anima-related recipes that require Anima Synthesis. Fishing has some sort of new frog fishing with that keyitem, and Woodworking crafters with the Lumberjack keyitem can do new higher level recipes that create more lumber per log synth'd. The rest of the recipes require the Purification and Ensorcelment keyitems, which are used to make certain special crafting materials that are then utilized to make all that new Enchantment equipment and weapons. For a full list of all the new materials, equipment and recipes as they become available, check here.

How do I get these keyitems?
You purchase them with Guild Points, which are obtained by turning in specific crafted items to the Guildworker's Union Representative at the respective guilds. Look for the NPC at your guild with the funky apron on, and they'll explain it all; there are discussions of the Guild Point elsewhere on this forum.

honestly, woodworking needs more ways to make gil
