Spell-Storing weapon + Magus' Spellstrike

Question

Okay, I've seen a few questions about this but not the exact question I have so I figure it's reasonable to ask.

Let's assume the following situation, I have a magus with a spell-storing weapon with, let's say, Frigid Touch stored in it. I enter combat and cast Shocking grasp using my standard action, move to my target and use Spellstrike to take the free touch attack I get with Shocking grasp to deliver the spell through my weapon.

Assuming I hit, I deal weapon damage + the damage of Shocking Grasp, let's assume a 5th level magus wielding a rapier and say this is 1d6 piercing + 5d6 electricity.

As I have hit my target with my weapon and dealt weapon damage, can I now use a follow-up free action to discharge the stored Frigid Touch using the Spell-Storing element of the weapon for an additional 4d6 cold damage and a chance to stagger the enemy?

Or do I have to choose to discharge the stored spell OR use Spellstrike?

Answer 1

Spellstrike doesn’t have any special interaction with spell storing, which is to say, you can use spell storing as normal after hitting someone with your weapon, whether that hit was done using spellstrike or any other means.¹ As long as you’ve hit someone with the spell storing weapon, and it’s still your turn, you are allowed to use the spell in the weapon. The only way something could prevent you from using the spell is if it explicitly said you can’t use spell storing with it—and as far as I know, nothing in the game says that.

1. _{Attacks of opportunity are questionable—you generally cannot take free actions outside your turn, and it’s not clear if the “interruption” offered by an attack of opportunity is an exception to this or not. I generally feel the game works better if it is, but spell storing is definitely one of the cases where I can see why a GM wouldn’t want it to.}
