I see Tec as a combination of Muscle Memory and Mental Willpower. Muscle memory does not let you hit harder, it lets you move with practiced accuracy. Mental Willpower does not let you fry someone's nerves, it lets you alter their thoughts... to an extent... because they have their own willpower too.
Edit: To elaborate on Omni's post, the nerve thing would still be based on Attack. XD You'd just bypass aim and Homing by having Telepathy - and even that I'm not sure would fly.
