Magehounds are Halruaa's inquisitors. Conceived in Halruaa's earliest days as a means of preventing the kind of tragedy Karsas brought upon the Netherese, magehounds are tasked with keeping renegade practitioners in check. They test the jordaini for magical ability or illegal usage of the same, track down renegade wizards, and enforce Halruaa's most important laws -- those governing the use of magic. They are feared by everyone to some degree, for they are considered above the normal laws of the land. They answer only to the Council of Elders, and even those members are not immune to a magehound's wrath, should they cross the line into forbidden arcane realms.
Typically, only wizards or clerics have the insight and dedication to become a Halruaan magehound. In very rare instances, paladins or rangers opt to pursue a more militant path toward becoming a magehound, but bards and druids lack the temperament required. Occasionally, sorcerers become magehounds, and in some ways, they are considered more appropriate for the task because of their perverse (by Halruaan standards) arcane nature.
The job of a Halruaan magehound is often a solitary one. Rarely do two or more magehounds band together to track down a foe, unless such prey is particularly powerful or difficult to capture. More often, a magehound has one or more companions or cohorts to assist her in her hunting. These companions provide skills and abilities to compliment the magehound's own, making her task a little bit easier.
Hit Die: d4.
To qualify to become a Halruaan magehound, a character must fulfill all the following criteria.
Skills: Spellcraft 10 ranks.
Feats: Combat Casting, Great Fortitude, Lightning Reflexes.
Spellcasting: Ability to cast 4th-level arcane or divine spells. Ability to cast at least three spells that require Fortitude saves and at least three spells that require Reflex saves. (A spell that inflicts damage but allows no saving throw can substitute for any of these required spells.)
The Halruaan magehound's class skills (and the key ability for each skill) are Concentration (Con), Craft (Int), Gather Information (Cha), Intimidate (Cha), Knowledge (any) (Int), and Spellcraft (Int). See Chapter 4: Skills in the Player's Handbook for skill descriptions.
Skill Points at Each Level: 2 + Int modifier.
All of the following are class features of the Halruaan magehound prestige class.
Weapon and Armor Proficiency: The Halruaan magehound gains no proficiency with any weapon or armor.
Spells Per Day: A Halruaan magehound continues training in magic. Thus, when a new magehound level is gained (except at 4th and 8th level), the character gains new spells known and spells per day as if she had also gained a level in an arcane or divine spellcasting class she belonged to before she added the prestige class. She does not, however, gain any other benefit a character of that class would have gained (improved chance of turning or rebuking undead, bonus metamagic or item creation feats, bard or assassin abilities, and so on). This essentially means that she adds the level of Halruaan magehound to the level of some other spellcasting class the character has, then determines spells per day, spells known, and caster level accordingly.
If a character had more than one spellcasting class before she became a Halruaan magehound, she must decide to which class she adds each level of Halruaan magehound for the purpose of determining spells per day.
Improved Saves: The Halruaan magehound learns to improve her resistance to the very sorts of spells she uses against others. At 1st level, she gains a +1 resistance bonus on her saves against spells and spell-like abilities. This bonus increases by +1 every 2 levels above 1st.
Sense Latent Magic (Sp): The Halruaan magehound develops a keen awareness of the possibility of magic in any living creature. The magehound can use sense latent magic at will as a wizard whose level is equal to her Halruaan magehound level plus her highest arcane spellcaster level.
Spell Resistance (Ex): The Halruaan magehound develops resistance to the very magic she is fighting. At 4th level, she gains a spell resistance equal to 15 + her class level.
Antimagic Aura (Sp): The Halruaan magehound develops a powerful tool to thwart the mages she is hunting. At 10th level, the magehound can use antimagic aura once per day as a wizard whose level is equal to her Halruaan magehound level plus her highest arcane spellcaster level.
