Some food for thought...
Mark (Ex): A bloodhound can target, or mark, an individual humanoid or monstrous humanoid foe to better hunt that enemy. To do so, the bloodhound must focus on a foe who is present and visible, or on the depiction or description of one who is not, for 10 minutes. Any interruption ruins the attempt and forces the bloodhound to start the process again. Once this study is complete, that target is called a mark.
A bloodhound adds his bloodhound level as an insight bonus on all Gather Information, Listen, Search, Spot, and Survival checks made to determine the whereabouts of a mark. As a bloodhound gains levels, he gains additional abilities that can be used against a mark.
If a bloodhound chooses a new mark before apprehending an existing one, the latter becomes unmarked, and the bloodhound loses experience points equal to the amount he would have earned for defeating that creature. A blood hound can choose a mark only once a week.
Initially, a bloodhound can have only one mark at a time. For every three bloodhound levels gained beyond 1st, a bloodhound can have one additional mark, but only if all the marks are chosen during the same process (see above). For example, a 4th-level bloodhound could mark two bugbears in teh same group of prisoners, or the depictions of a bugbear and a hobgoblin if both were studied at the same time. If a bloodhound gives up on apprehending any of his marks, all remaining marked creatures become unmarked as described above.
Inscrutable Mind (Ex): Any creature attempting to establish a telepathic link to a phiuhl's mind (via detect thoughts, a psionic ability, dominate monster, and so on) must make a Will save (DC 14) or suffer the effects of feeblemind as cast by a 9th-level sorcerer. The save DC is Charisma-based.
Feed (Su): When a barghest slays a humanoid opponent, it can feed on the corpse, devouring both flesh and life force, as a full-round action. Feeding destroys the victim’s body and prevents any form of raising or resurrection that requires part of the corpse. There is a 50% chance that a wish, miracle, or true resurrection spell can restore a devoured victim to life. Check once for each destroyed creature. If the check fails, the creature cannot be brought back to life by mortal magic.
Split (Ex): Slashing and piercing weapons deal no damage to a black pudding. Instead the creature splits into two identical puddings, each with half of the original’s current hit points (round down). A pudding with 10 hit points or less cannot be further split and dies if reduced to 0 hit points.
