Patch Tech (spell) page 139. The spell indicates that it has a "Close" range and Targets "one technological item", but the description text states that "You gain a +3 insight bonus to Engineering checks to arm explosives, disable devices, and repair items." It's not clear how casting the spell on an object permits this insight bonus to you - at best if you're applying it to the object to be Engineered it's still unclear. Also, it seems your allies cannot take advantage of this?
My best guess is the spell is either a mishmash of two ideas (a personal skill boost and a repair action) that was never fully finalized, or it was changed during development and one of these discrepancies is a remnant of a past version. Either way, it's not clear how a player can use this in this form without GM intervention.
