If I only use my crossbow for grenades…

…how does % increased grenade damage stack up against % increased physical damage.

I’m doing a wonky spear/crossbow alt, aggravating bleeds and ignites with Shaitha’s Spear, and getting ignite magnitude from explosive grenades and spreading it with oil grenades.

I realize it’s just a less effective incinerate/oil grenade knock off, but I like spearfield, and have a rather swanky double corrupted version of the spear.
