Mathematically speaking, I'm trying to determine if Bracers of Defense (AC+2) is better than a Cloak of Displacement, which causes all attackers to have disadvantage on attack rolls against you.
If it's pertinent, I'm a monk, my CLcharacter level is 15, and my AC without the bracers is 18. I don't have any other sources that will consistently impose disadvantage on my opponent's attacks. I'm trying to choose between these two items and I'm trying to determine which one would ultimately result in less loss of HP.
It's been too long since my high school statistics classes, so I'm finding the advantage/disadvantage statistics threads too hard to follow and don't really take into account AC.
