Hello!
I am trying to figure out how the Foo Lion's Stony Defense ability works with its damage reduction. Here's what it says
Stony Defense (Su)
A number of times per day equal to its Hit Dice, a foo creature can harden its skin to unyielding stone as an immediate action. It gains hardness 8 until the end of its next turn, but its speed is reduced by 10 feet for the same duration.
On top of that it already has DR5/Bludgeoning. So my question here is if its total DR becomes 13 against slashing/piercing (8 vs Bludgeoning). Because of my understanding 'hardness' work exactly the same as DR for objects, though this is a creature, does it stack?
