How to use set data to vessel gems.
Change Data1 to desired stored favor value. I tested as high as 5k, didn’t try higher.
NOTE: You only get three uses max out of a gem, so it will disappear long before you get to use a high favor setting. Thus, the max I would use is 300 (100 favor x 3 uses). There is no settable value for gem usage, I assume it is an algorithm based on QL.
