The artillery strike spell is supposed to have 3x times scaling from grenade dmg multipliers, instead it has no scaling at all.

Hm, I'll check it later. I may forget about it though. And, perhaps, there are some other issues with the spell.

Nvm, they do scale with something but it's not shown anywhere ( before, it was shown in "bonuses" and thus also on research).

might be scaling with overall dmg form rpg items

Um, probably, it won't show anywhere because the spell works "dynamically" and applies damage by scripts. (it seems doesn't apply damage on buildings, although I didn't check it). Also, the damage seems weirdly applies to entities because of maximum health...
