I tried posting this the other day but I had some issues with the copy and paste from a site so I had to post it on another forum and then copy and post it from that forum to this forum. So here it is.
I got this from OPRainfalls site.
Gem Crafting 101 Part 1
Each material has a value for certain stats enhancers. Say, Agility Up or Poison Defense. To gain a Gem from materials, you need to raise the stat above 100. This will ensure a Gem will be created. The trick is to select Crystals and Cylinders until you reach a 100+ value on the stat of your preference. This is a delicate proccess, as when the value is over 100 you can not add any more to it. So it's imporant to keep materials for crafting in order.
Thankfully the game helps you, with highlighting the material compatiable with another material. This means they enhance at least one of the stats of your chosen material. Continue until youâve reached a 100+ stat and try to not have more than 3 or 4 stat enhancement affected in total.
Gem Crafting 101 Part 2
This is probably the most confusing part as it involves Flames, Fever and whatnot. This is where is get's really confusing, but in short: during crafting the Shooter and the Engineer will boost the stat values of the enhancements chosen through your materials and will fill the Cylinder gauge respectively. How many times they will boost and fill is dependent upon the Affinity of the chosen characters.
A good exmaple would be to put Reyn in Shooter and Shulk in Engineer roles, but this may vary depending upon your personal game. Then select a balanced approach of the best boost of the Shooter and the most stable Flames of the Engineer (with a high Affinity of course)
Now the animation will start. You can fast-forward through it by holding the A button. Depending upon the selection of your Shooter and Engineer (and just plain luck) your enhancements will be boosted and your Cylinder Gauge (the green gauge right of the ehancements list) will fill up. When they are done, all enhancements with values above 100 will be converted into Gems. If you have values above 200 these will display as âHeatâ and will generate a higher Rank Gem instead (as a bonus it also boosts other values)!
Gem Crafting 101 Part 3
Now comes the crucial part: any enhancement values under 100 will be up for Cylindration. This is where the Cylinder Gauge comes into play. Depending upon the Cylinder number on top, you can select just as many enhancement values. Each selected value will be ârecycledâ into a Cylinder, to be used as a future material in adifferent crafting session. Once your Cylinder amount is empty, all remaining enhancement values will be lost.
This is why you should aim for 3 to 4 enhancement values while selecting materials as mentioned earlier. If you go overboard with 5-7 values, you might lose materials in the end as they cannot be Cylindrized. Of course, you can still hit an unlucky crafting streak and only generate 2 Cylinders even with a great character couple, but thatâs the luck of the draw. What works best in terms of the amount of values chosen is wholly dependent upon the charactersâ ability as a Shooter or Engineer and their Affinity.
Once youâve selected all values for Cylindration, the game will hand you the resulting Cylinders and Gems to put into your inventory. As space is limited, be sure you have enough space left before starting the process. Youâll then be asked to continue for another session or quit crafting.
These are the basics of Gem Crafting, there is so much to this mechanic that we can't even keep it all in parts. We hope this info was beneficial to you, and help's you all on your adventure in the world of Xenoblade.
Also the game is 24 days away from release in North America do you have it preordered?
