The spell 'barkskin' is a druidic enchantment that temporarily changes the target's top layer of skin into bark.  The toughness of the bark depends on the level of the caster, if cast by a low level spellcaster, the target's skin will appear to be tinted green, and will take on the appearance of a young, green tree before the bark turns brown and wrinkles.  Medium level casters will produce a tough brown skin on the target, and higher level spellcasters can completely change the target's skin into a thick layer of wrinkled, dark brown wood, giving an enormous bonus to the target's Armor Class.
