Unfortunately, since the VS plugins are obfuscated, I don't know what they do to the damage formula to be able to use the damage styles.
In theory, since all my plugin does is replace some keywords with a formula, you should be able to set the formula to just return a flat number and it should work with the power damage style, but that's assuming they didn't modify the damage formula to the point where it ignores my changes.
