I was curious about a few mechanics of weapon/armor crafting and heat levels.

Currently I have Brandish sword that is about to hit heat level 10 and am heading the Glacius route. I know that when crafting an item there is an X percentage of special variance. Normal item attributes plus an additional one, Lets say medium damage bonus to beasts for example.

1. What is that percentage or chance of crafting an item with the special variance

and

2. Does leveling an item, to be used for the next star lvl progression of said item, to heat lvl 10 increase the chances of creating the next item with a special variance? (i.e 2 star brandish heat lvl 10 for iceburst brandish)

From what I have gathered so far it does not. Are there any ways of increasing the chance of a special variant? and there any roll over bonuses for using a heat lvl 10 item for a recipe versus one that simply meets the requirements like a lvl 1 item.

It would be nice if there were some sort of bonus for slogging through and max leveling an item. As it stands you can not sell a used item, so there is no resale value there. Would be nice if using a heat lvl 10 item for the next star lvl item in the tree would give you say a 35% chance of creating the new weapon with a special variant.
