Titan's Shutdown

[Vomitus]

U sure... last I checked it reduced armor to fortified. that would affect all attacks

Nor type of armor neither its value affect actual damage taken from magic-class damage. It only affects magic type of 'normal' attack like if creep for ex had an attack type 'Magic' with that blue icon on it.
This was said not long ago by Exodus, as I remember, but I don't remember where or when exactly.
