Divine Power + Thorn Body. Work together?

[Stephen Ede]

If you cast Thorn Body and then Divine Power does Thorn Body get bonus damage from the Divine Power?
I think it comes down to does the spikes from the Thorn Body count as weapons.

Thorn body does not create any weapons. It applies a damage rider to contact with your body, and a damage rider bonus to natural attacks and unarmed strikes.

The real question is: does Divine Power apply to natural attacks and unarmed strikes?

These are not weapons so no bonus damage.

Unless you're also a monk in which case your unarmed strike counts as a manufactured weapon for spells like divine power. Still no help with creatures striking you from that spell though.

Last I saw Divine Power applied to Rays and the term "Weapons" was also defined to included Unarmed Strikes and Natural Attacks (Manufactured weapons is the term that excludes unarmed strikes and Natural attacks).

Divine Power helps when you attack something, but it shouldn't add damage to something passive. So the short answer is no.

The slightly longer answer is both spells will stack for adding damage to an unarmed attack. If something hits you the thorn body causes damage in response, but it isn't you're attack so Divine Power and other effects that pump up your attack add nothing.

If that wasn't the case, then you could argue that everybody applies strength mod to Thorns, and Power Attack since both modify your melee damage and this is damage that only happens in melee.

"Natural Attacks: Attacks made with natural weapons,(...)"

Seriously, Natural attacks are called "natural weapons" more often than "natural attacks". Check spells like Magic Fang of Magic Weapon, for instance.
