[CK Question] Thunderous Sound Effect for spells, possible?

[Lyman the Lunatic]

Hi, I'm not actually a coder or a modder, so I don't really know much about the CK.

So I've downloaded a spell mod from the Nexus (Smites & Strikes) & I find it to be underwhelming so I just want to change things up a bit for my own use. The spells work by giving your character an attack buff, the the spells will come to effect when your weapon hits the enemy. Right now, I want to change the sound effect when the enemy got hit with the weapon because the vanilla "twack" is just lame. I gave the VOCShoutFXUnrelentingForceThunderC and nothing changes. Or is it impossible because the hit effect is determined by the weapon?

Thanks.
