Calculating Animal Companions AC?

[DM Bacon]

Hey, quick question from one of my players. When calculating an animal companion's ac, do you start from 10 (like a PC), then add their natural armor, then everything else they might have? Or does it start from 0?

[Shane Weber]

You start from 10, just like everyone else.

[Aratrok]

Everything starts with a base AC of 10. Creatures, objects, trees, everything.

[Adamantine Dragon]

You start from 10, like a PC.

Thanks for the quick responses. That's what we thought, we just wanted to make sure.
