Quick frenzy synergy question

[mattis]

Does anyone know how berserk's % bonus magic damage interacts with frenzy?

If it's % of the weapon's base damage it seems pretty useless...

In the beta it converted that % of physical damage into magic damage; I suspect it's the same in 1.10. You can easily test it with one point into berserk (which you'd use anyway for handling PI's); if your damage doesn't change by even one point then it must be converting physical into magical.

The synergy is quite useful when frenzying against monsters with high physical resistance.
