For a strange reason this spell can appear in Necropolis' Mage Guild, even though they are immune to it.
I wonder if this condition can be dispelled. Disrupting ray effects on D cannot, and this is a A/D stack modifier so could this be similar?
Frenzy vs. Behemoths
tested in SoD + HD mod
28 att. hero = 42 attack = 946 damage
exp. frenzy = 14(42) attack = 429 damage => real attack: 18
14 att. hero = 28 attack = 638 damage
bas. frenzy = 14(28) attack = 407 damage => real attack: 16
