How to be more crafty?

I am trying crafting some potions, but the game says that I am not yet crafty enought to craft that craft.

Where I can see how crafty I am and how to become more crafty?

Your crafting skills are at the bottom right of your character page. To increase them, you must have selected them as one of your starting skill and pick it at level up.

If you have not chosen a craft skill that you can advance, the options are rather limited.

Craft skills can be buffed. You just have to be lucky enough to find an item with the buff. For example, Tinkerer's Goggles.

Note that this will increase the skill level. It won't give the other assorted benefits of advancing the crafting level as part of a character level.
