Unable to use the 74 Skill "Reuse"

It has an unknown random chance of proc on the step that fills your quality bar to 100%. If it doesn't proc then it won't proc later. Also, if it does proc, it'll stay lit until you either use it or finish the synthesis.

Do you mean with proc like the condition good or excellent?

Then is the description wrong, i thought, i can use it every time and with a chance, i get something back - this is really stupid tbh

It's the other way around but still the same effect. There's a chance you're able to use it, but each time you are able to it will always give you something back.

From my experience it seems to always be only 1 item returned and it seems that it's always the first item in the list of materials for the recipe.

The description clearly states "Chance to become available upon reaching maximum item quality."
