Consider a Sword of Spell Storing, and put Ray of Clumsiness into it.
Doesn't work. The spell storing quality only allows the weapon to accept a 'targetted' spell. Ray of clumsiness is, in fact, not a targetted spell (Effect: ray), so isn't eligible for use here.
The spell does a Dex penalty of D6 +1 per two caster levels (Maximum +5). Empowering it can make it instantly disabling to a lot of people. Remember that, while a Ring of Spell Storing always stores the spell at the minimum caster level needed to cast it, Spell Storing weapons don't have that caveat.
So empowered, even at 1st level caster, does a minimum of 10 Dex.
I'm not sure how you get this, either. Empower spell multiplies the variable components of the spell effect by 1.5. So, that 1d6 gets multiplied, not the full effect of the spell. And the minimum of 1d6 x 1.5 is... 1 (fractions round down). Of course, you then add half the caster level (again, rounded down), but that still doesn't get you close to a minimum of 10!
