Suggestion | Call the Pyre should scale with global dmg modifiers

I was excited to make a character that focuses on global crit multi and fire damage in order to scale the Graft. You know, the whole league being about those little limbs growing out of my back, I though it would be cool to make a character that relies solely on them to deal damage. To my surprise, the added damage doesn't seem to be affected by global modifiers, like crit chance, crit multi or %dmg increases.

This killed my motivation to explore this league further unfortunately. I wonder if this is a bug. If not, please consider this post as a suggestion to make those modifiers work with grafts, so that those charred fingernails on xoph's graft don't go to waste.
