Deny Succor (Su)
Source: Advanced Class Guide, p. 41
The shaman can place this hex on a single creature within 30 feet. The target does not heal damage from cure spells and does not benefit from any spells or effects that remove conditions. This effect lasts for a number of rounds equal to 1/2 the shaman’s level. A successful Will saving throw negates this effect. Whether or not the saving throw is successful, the creature cannot be the target of this hex again for 24 hours.
