Armor stacks, but its returns are diminishing the higher you go. You might be thinking of the auras not stacking from Vlaads and Assault.
But, typically you shouldn't get both. Mostly because they're both expensive and armor stacking doesn't help that much.
huh, i thought a changelog said shiva and AC armor does not stack anymore. .must of misread, but yeah, way too expensive to farm both of them in dota now, other items are more needed and games don't last long enough for you to sit ricing.
