So what effect shall these spells have? Render them inert/inanimate for 1 round/hour/day per caster level?
Along those same lines, would an erase spell reverse the negative effects?
Basically like a touch attack. Sure! Revising...
A statue that walks is affected normally by any symbol, glyph of warding or sepia snake sigil spell. Furthermore, any of these spells can be transfered the golem as if it were an surface; the caster inscribes the symbol, glyph, or sigil on another object and then must succeed on a touch attack against the golem with that object within 1 minute/hour???. If the statue that walks succeeds at a Will save (DC equals spell DC) the inscribed spell dissipates harmlessly, but if it fails the save the golem is rendered immobile and helpless until the symbol, glyph, or sigil is discharged.
I can live with that.
