Ward of Stone (Su)
Source: Advanced Class Guide, p. 45
The shaman touches a willing creature (including herself) and grants a ward of stone. The next time the warded creature is struck with a melee attack, it is treated as if it has DR 5/adamantine. This ward lasts for 1 minute, after which it fades away if not already expended. At 8th and 16th levels, the ward lasts for one additional attack. A creature affected by this hex cannot be affected by it again for 24 hours.
Spirit Animal: The shaman’s spirit animal looks as though it’s made out of earth and stone, with tiny gemstones embedded in its flesh. The animal gains DR 5/adamantine. Spirit Ability: A shaman who chooses the stone spirit as her spirit or wandering spirit gains the following ability.
