What does Armor Even Do in TFT?
So, Thornmail, one of the highest armor items in the game, gives you 40 armor in TFT. Meanwhile, the Noble buff gives all units 100 armor. But after I get it I don't notice any real increase in tankiness. It doesn't seem to make assassins have any harder time killing me through critical strikes. You would think 100 armor would be a pretty significant reduction, even if the enemy has a Void comp (and they don't always).
