Arcanum Schematics

I'm a level 11 character, have 13 Dx and 11 In, have 'activated' the Trap Springer so I can build them. Problem has arisen. It now displays a 'do not have the required expertise'? I am at the mechanical assistant level, so what is wrong? Please help

Check the intellegence requirement for making that trap. When you hold the cursor over the trap list the requirements will show in the text window.

 

He has enough INT, I think. What he needs is manuals.

Open your character's profile and look at the Mechanics schematics tree. There must be a number next to the symbol of mechanics, that is your expertise. Now look at the schematic you want and check out how much expertise you NEED. Then you can up your expertise either by learning more schematics from the same tree or by buying manuals in the discipline you need from the bookseller at the University of Tarant.
