I am wondering what the ruling would be on a creature under the effects of the Barkskin spell that then casts the Shield spell as a reaction.
Barkskin states:
Until the spell ends, the target’s skin has a rough, bark-like appearance, and the target’s AC can’t be less than 16, regardless of what kind of armor it is wearing.
Shield states:
Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack…
Which of the following results would occur?
A) The creature’s AC becomes 21, adding the +5 bonus from Shield to their AC from barkskin;
B) The creature applies the +5 bonus from Shield to their base AC and if it is higher then 16, it overrules Barkskin.
Best Answer
It depends on your original AC
Jeremy E. Crawford says in the Sage Advice Compendium (thanks to Daze 413 for the link):
So if your original AC is 12 or greater you add the +5 from shield to that. Otherwise it remains a 16.
