Nature Resistance Totem is an Air totem, and thus cannot be used at the same time as another air totem. Like all shaman totems it only has 5 hit points and is easily targeted and destroyed. When used in a raid group it will affect everyone in the raid who is in range.
The totem can greatly reduce the damage taken while fighting against casters that rely heavily on Nature magic, or on fights with a lot of nature damage. It also offers protection against Nature-based poisons and diseases.
