What would be the appropriate level for True Strike as a focus spell?

GMG guidelines for items say 1st level spell muiltiple times per day is a 5th level item but I am convinced that is too low for "True Strike on a stick".

I'm aware of the Staff Wizard Archetype in APG but I feel that does a different thing by expending spell slots for it.

I'm experimenting with True Strike:

(a) as a focus spell

(b) on a magic stick

(c) as metamagic allowing a wizard to modify a spell as cast or memorized.

Honestly? Depends on who it is for. True Strike on a Stick as a Fighter ability is going to be a very different thing than as a Rogue ability or a Wizard ability.
