Help! Enginnering Upgrade is hardcoded!

[Rykon-V73]

I wanted to remove the buff from this spell. I made a new one, based on the spell from the title, but no matter what I do, the spikes are still there. I removed the buffs, I changed the buff effects. Nothing. Is there no way to use this spell?

Remove the spikes from the original buff.

Wait... does that work? Let me try.

Well, it did work, but replaced nothingness with the Gear Aura, as the hero is mechanical. Thanks, Uncle!
