Class Features

All the following are class features of the demonologist prestige class.

Weapon and Armor Proficiency: Demonologists are proficient with no weapons, armor, or shields.

Spells: Beginning at 1st level, a demonologist gains the ability to cast a small number of arcane spells. To cast a spell, the demonologist must have a Charisma score of at least 10 + the spell's level, so a demonologist with a Charisma of 10 or lower cannot cast these spells. Demonologist bonus spells are based on Charisma, and saving throws against these spells have a DC of 10 + spell level + Charisma modifier. The demonologist's spell list appears below; a demonologist has access to any spell on the list and need not prepare those spells ahead of time, just like a sorcerer. A demonologist casts spells just as a sorcerer does.

Charm Demon (Sp): A 1st-level demonologist can attempt to charm a chaotic evil outsider, as described in the charm person spell, once per day. The demon does not get to use its spell resistance, though it can make a saving throw as normal (DC 11 + demonologist's Cha modifier).

Quasit Familiar (Ex): A 2nd-level demonologist gains a quasit as a familiar, whether he wants it or not. If the demonologist already has a familiar, the quasit devours it and takes its place, but the character suffers no experience point loss. The quasit is treated as a normal familiar, using the class level of the demonologist as the master's level (see the Familiars section in Chapter 3 of the Player's Handbook for familiar abilities).

Summoning Mastery (Su): When a demonologist of 3rd level or higher casts a summon monster spell, it is treated as the equivalent spell of two levels higher for purposes of summoning chaotic evil creatures. For example, a demonologist refers to the summon monster IV list for chaotic evil outsiders when casting summon monster II. At 6th level, the demonologist refers to the summoning list three levels higher than the one for the summon monster spell he is casting. At 9th level, the demonologist refers to the list four levels higher.

Resistances (Su): A demonologist who reaches 4th level gains acid resistance 10, cold resistance 10, fire resist- ance 10, and electricity resistance 20.

Poison Immunity (Ex): A 5th-level demonologist is immune to poison.

Hold Demon (Sp): A 7th-level demonologist can attempt to hold a chaotic evil outsider, as described in the hold person spell, once per day. The demon does not get to use its spell resistance, though it can make a saving throw as normal (DC 12 + demonologist's Cha modifier).

Telepathy (Su): An 8th-level demonologist can communicate telepathically with any creature within 100 feet that has a language, just as a tanar'ri can.

Dominate Demon (Sp): A 10th-level demonologist can attempt to dominate a chaotic evil outsider, as described in the dominate person spell, once per day. The demon does not get its spell resistance, but it can make a saving throw as normal (DC 15 + demonologist's Cha modifier).
