   "description": "The touched weapon becomes an awe-inspiring instrument for 1 min./level: it gains a +2 sacred bonus on damage rolls, and a creature struck by a critical hit from it becomes shaken for 1 round (a mind-affecting fear effect). Will negates (harmless, object). Simplified: the engine has no weapon-targeted buff track and no self-buff encoding that preserves the pinned default-policy casting order, so no mechanical effect is applied."
