There is an unarmored bonus associated with Sorcerors in 5e that is not listed on the character sheets. Page 102 states: Draconic Resilience As magic flows through your body, it causes physical traits of your dragon ancestors to emerge. At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class. Additionally, parts of your skin are covered by a thin sheen of dragon-like scales. When you aren’t wearing armor, your AC equals 13 + your Dexterity modifier. The Armour tab of the 5e Character Sheet shows Unarmored Defense Bonuses for both barbarians and monks, but nothing for Draconic Bloodline Sorcs. I am using Google Chrome in Windows 8 and Windows 7.1 and both display the same thing, so I'm assuming this is not a rendering or CSS bug. Please let me know if there's anything additional you need from me.
