Total Spell Incompetence

Total Spell Incompetence is a limitation on Magery found in GURPS Thaumatology.
It is effectively only a form of Limited Magery 0 though because taking it on levels beyond 0 seems pointless.
It would cost 4/level for that talent which applies to Thaumatology (which itself can be bought up for 4/level) and to the twice-ever-per-item rolls for items on first-glance / first-touch, which could probably be bought up more cheaply at +5%/level by buying Reliable for Magery 0.
