Edit -- I was planning to post this in the pinned D&D 5th Edition by Roll20 thread that's been running for 5 years but it apparently was closed (to my surprise) since no one had posted for over 2 months. One of my players runs a barbarian with the Unarmored Defense class option. This causes the AC calculation to be 10 + Dex bonus (2) + Con bonus (3) = 15. (Number in parentheses are the actual bonuses for this character.) However, recently he got a Barrier Tattoo (Rare) that grants you an Armor Class of 15 + your Dexterity modifier (maximum of +2) = 16 Per the 5e rules you cannot stack these two calculations. When I activate the Barrier Tattoo in the item list on the character sheet, it calculates the AC as 31 because it is starting at the 15 as calculated using the Unarmored Defense class option and then adding the result of the Barrier Tattoo (Rare) calculation to this resulting in an AC of 31 (which really makes the player happy but...) I've removed the Unarmored Defense class option from his sheet but that doesn't remove the Unarmored Defense class option AC calculation. Short of rebuilding his sheet for this 13th level barbarian, is there a way can I fix this?
