You can create holy water that burns with your intense hatred of the undead.
Benefit: You can cast bless water a number of times per day equal to your Wisdom modifier with a caster level equal to your total Hit Dice (HD). If you have 8 HD or more, thrown holy water that you create with this ability is more potent, dealing 4d4 points of damage to undead and evil outsiders struck by a direct hit. If you have 16 or more HD, the damage dealt by thrown holy water you create increases to 8d4 points of damage to undead and evil outsiders struck by a direct hit. Vulnerable creatures hit by the splash still take 1 point of damage regardless of your HD. Holy water you create deals increased damage only when you throw it (not when you douse a creature with it). If given to another creature, it functions as normal holy water.
About Vampire Hunter Technique Feats
At their most basic level, vampire hunter technique feats are a mixture of fighting methods, disciplines, and stories passed down by vampire hunters successful enough to share their methods. Some are known battle tactics that fighters the world over have shared. Others meld magic and finesse to grant mortals an edge over the undead. The most dangerous invite the corruption of the undead into the hunter, allowing him to turn vampires’ powers and tools against them. The strangest rely on mysteries of the old world and possibly even those beyond to confound creatures who think themselves immortal.
Vampire hunter technique feats can only be accessed by members of the vampire hunter class or those who have the Vampire Hunter Tradition feat (or a similar ability). Unless such a feat specifically says otherwise, other characters cannot choose these feats, even if they meet the prerequisites.
