Chance of Masterwork ?.

[Grimaldus]

Been crafting items now with Masterwork status, and adding items
in the slot for masterwork which has 40%chance of masterwork to
increase stats by 10%, but when i craft the item, nothing happens
and all it says is still "40% chance of masterwork 10% increase all stats" on the info window.

It only triggers when you craft the item, you'll see all the stats flash white and be buffed by 10%.
If it doesn't trigger, then the masterwork buff failed and you'll have to try crafting a new item again.

Seems like the 10% increas in stats isn't really worth the very rare dragontooth.
I'm crafting an armor with 280 Def, 38Fire/36Cold/16Melee resistance,
and a 10% increase to that is very very minor.. not a make or break proc.

Its RNG Make sure to save when you use rare materials.

[Grimaldus]

Apparently it's no RNG. The outcome of the craft is already decided when
the rare crafted items drops from the kill. So Dragon's Teeth that gives 40% chance
for mastercraft, has it's rng already decided when the teeth drops,
doesn't matter how many times you reload a save.

The only way to get a mastercraft is to save, use all lowend materials
and remember which round of crafting that was a successful mastercraft.

It also works to have a Masterwork Schematic.
