Vulnerability Curse

Feats

The witch can make her enemies vulnerable to energy. This hex lasts for a number of rounds equal to the witch's level, during which any energy resistance or energy immunities on the target are suppressed. A successful Will save reduces this to just 1 round. Whether or not the save is successful, that creature cannot be the target of this hex again for 1 day.
