For lack of a better term, animal hide is the natural outer covering of creatures built to withstand against the elements or attacks. This generally affects non-humanoid creatures though some humanoid creatures might also have tougher or more element resistant hides as well.

Attack or Defense Dice Legend: P/D = Poison/Disease, F = Freezing, B/A = Burning/Acid, E=Electricity, P = Piercing, B = Bludgeoning, S = Slashing The multiplying factor is how many dice are added for that attack or defense. When the defenses are all added together, dice numbers with a fraction less than one half are rounded down or rounded up otherwise.
