Your skin, fur or scales are particularly tough. You gain a bonus to natural armour equal to your Mettle against crush damage, half of that against cut and stab damage, and a quarter of that against heat, cold, shock and poison damage. If your Mettle exceeds 10 then only every second point beyond that counts. The natural armour bonus from Mettle cannot exceed your normal natural armour.
