I have a torrent crystal, that I've had since I started playing, but I have no idea how I got it. Valentine's day is in february, and I didn't even have the game then, and I've never given items to any guild. How did I get this thing?
Ok, so I finally achieved Novice in cooking! I earned some guild points through turning in tortillas, and pick up a Torrent Crystal. Now I know what you're thinking "Who wants to sign a juice?" well... I wanted to sign something, so I try to synth a Pineapple Juice, and it synths, but the juice that was synthed wasn't signed. (Also, I'm a level above Pineapple juice and got a .1 skillup, is that normal with these?) Thanks a lot.
You can get this crystals from a NPC inside of the different Crafting Guilds. Once you have reached Novice the NPC will accept certain items at certain times. Those items that you trade will give you Guild Points, and those points you can trade for these crystals and other specific guild items like the aprons and crafting specticals.
