Currently UV are very hard to craft, so i was thinking if you use more materials you should have a better chance of getting one. But I would want to have it formulated (# of Stars x 0.001). Obviously this would be in effect if the crafter is using more Materials.

For example:

A Dusker coat needs 10 Green Shards, 3 Sharp Fangs, 2 Monster Bones, and 1 Bushy Tail. The increase of chance should depend on the amount of stars the materials have.

If I use 20 green shards instead of 10 I would get a 0.000% boost because is a 0-Star Material.
If I use 13 Sharp Fang instead of 3 I would get a 0.010% boost because it is a 1-Star Material.
If I use 12 Monster Bones instead of 2 I would get a 0.020% boost because it is a 2-Star Material.
And the same rule goes for the Bushy Tail.

I think this would balance out Energy Costs since you dont need to use all your energy to craft your items.

Another suggesting: Trinkets should be Craftable. Im not sure if they should be able to get UVs but they still should be craftable.
