Unlimited loyal animal followers who can cause vile damage? Sure.
Touch of HateSo it costs Violate Spell feat, which is a
good decent feat anyway if you've got Spell Focus Evil, Evil domain and like Vile damage, etc.
This then allows you to "Once per tenday" turn an animal into a Beast of Bane. This happens "instantaneously" on a failed save and the beast "follows your commands."
The limit is HD equal or less than your cleric level. Monsters with more HD are immune.
Animals, poor will saves. Dire Animals, okay will saves... but generally nothing to write home about. You can steal a ranger's pet or a druids companion and turn it against them...but it uses the player's will save with it's own modifier.
So... Dire Animals and Ripping Loving Creatures from their masters... that's pretty
good devious and enjoyable, but we also get to corrupt and buff them.
Add the Beast of Bane Template which is the
Beast of Xvim Template (Monsters of Faerun, pg 85) but with 1 minor (yet awesome) change.
note: The one I've found is 3.0 I don't think there's an updated version... if there is let me know.In summary:
+1 HD - which increases saves/BaB/skills as appropriate.
Physical Attacks: Damage die increases.
Special Attacks: Damage die increases.
Frightful Presence (Ex): Lasts 5D6 rounds.
Feed (Su): Advance like a Barghest.
Smite Good (Su): 1/day but Vile damage
Special Qualities: Immune to Fear, Poison, Darkvision 60ft. Also gains DR based on HD... the DR is /+1 so I guess it'd just be DR 5 or 10 /magic.
Abilities: Int is raised to 3 if lower, +4 Charisma.
Alignment: changes to Lawful Evil.
If the HD increases enough to give an extra feat, improved natural attack would stack with the damage die increase.
There's no duration for created creatures, no expiry, no limit to how many you can have... It's a save or die, based on your strong stat, but instead of dying, you turn into a bigger, stronger ally.
Just strikes me as abusable... I mean, advance them by having them eat their kills... deal vile damage... increase damage die...
The best trick I could think of would be if the frightful presences of multiple beasts are allowed to stack. That'd be an instant win for a lot of encounters.
