I have a pretty basic mod idea, want to give guards a perk that applies an effect to the player which then does some things. Problem is the effect never seems to work, I get nothing in my papyrus log?

I've added the perk to both the EncGuardSons/ImperialTemplate.

Perk is marked as hidden and has an entry point to apply combat spell on hit, with a condition GetIsReference target player.

Spell applies the magiceffect in question for 5 seconds, which is just a script effect with my script attached to it.

The Script
