Custom Skill formula

[Robert Dalkan Megapriest]

Hi :) what is the method to add a skill check to an item?
I'll explain; I created a "Weaponsmith" skill but I don't want to add it to the skill list, but to an item. So when the character wears that magical item (a belt for example) he can use it.

The problem is that, in addition to the DC speech that I don't want to appear, I can't enter bonuses, penalties and skills. So I was wondering what the "formula" was to be able to create a skill without having to create it in the skill list.

‌

Thank you and best regards

Roberto

PS: sorry for my bad english

There’s no way to have an item provide a custom skill, the only way to add new skills is to add them to the sheet directly.
