Does Sacred Aura stack additively or multiplicatively with Elune's Grace? 35 + 20 = 55%???

This could be big if true. It would make archers with lvl 3 sacred aura tankier than fiends and rifles against magic damage. 611 EHP.

You may have thought of this hero/unit combo already, but have you also thought about how damage resistance impacts on healing? Did you know that a lvl 2 holy light cancels out a tauren's worth of piercing damage on a footman? Similarly, if the assumption in the title of this thread is correct, a lvl 1 consecrate with lvl 3 sacred aura would cancel out a lvl 3 frost nova.

Let me put it another way: On archers, the effective magic resistance (compared to archers with no aura) conferred by sacred aura would be: 3/16, 5/16/, 7/16. That's 18.75%/ 31.25%/ 43.75%. In real, practical, simple terms, triple sacred aura comes close to halving the usual magic damage on archers! I'm talking about the actual damage you're used to experiencing... it almost halves that.

Sadly, I don't play any more, so I'm reduced to asking reddit about this. So bring on all the angry wc3 trolls with indiscriminate aggression for all living things and nothing relevant to say. Here's hoping I get an actual answer as well.

Note to mods: Flair is compulsory, apparently. But flair doesn't work on old.reddit. Please fix this. New reddit belongs to the enshittification NWO. Don't impose it on us.
