Duration: (level)/3 Cumulative: No This one spell is really special. It creates a protective shield of bark which increases hitpoints of the target and decreases damage done to target by 0.5% per caster level. But hard blows damages this shield and after few blows it gets destroyed. Then it takes some time for it to disappear, during which time it doesn\'t provide any bonus, only hampers agility. Also please note that armor of bark impedes movement significantly, reducing flee chance by half. This effect can be suppressed if you are protected by nature.
