one hunting horror
Saving Throw Will negates; Spell Resistance yes
This ritual calls forth an aspect or appendage of some nameless outer entity in the form of a hunting horror. It appears as though it is being squeezed through and billowing out of a tiny invisible opening in the air.
The hunting horror expects to have a substantial sacrifice prepared for it, or else it will accept the primary caster as the sacrifice and then depart. If the ritual is successful, the hunting horror first consumes the sacrificed creature and then claims any other offered items. A Large or larger creature of at least 4 HD is sufficient, though it is written that larger and more magical beings and other bribes such as magic items make it more likely the hunting horror will act favorably. Upon consuming the sacrifice, the hunting horror is willing to parley with its summoners rather than simply destroying them immediately. A caster must succeed at a Charisma check (DC 17) to convince the horror to undertake an action lasting no longer than 1 day per level. The negotiating caster cannot receive aid on this check, but gains a bonus if the sacrifice is especially powerful and unusual (+1 or +2) or if the offering includes a magic item worth at least 4,000 gp (+1, or +2 if worth at least 20,000 gp).
