Natural Weapons

Creatures with natural weapons such as fangs, claws, or horns may attack with any or all of them using their Fighting skill. Damage is stated for character races and beasts in their various descriptions.
Creatures with natural weapons are always considered armed. This means they aren’t Unarmed Defenders and foes fighting with Two Weapons gain no advantage against them. Here are a few additional notes for each type of attack:

BITE

The creature may bite a target it’s grappled (most attackers can only crush their prey).

CLAWS

+2 to Athletics (climbing) rolls on any rough or soft surface (not sheer steel, glass, etc.).

HORNS

Add +4 damage at the end of one Fighting action in which it Runs, moves at least 5″(10 yards), and successfully hits with its horns.
