All of the following are class features of the thrall of Demogorgon prestige class.

Weapon and Armor Proficiency: a thrall of demogorgon is proficient with all simple and martial weapons, with all types of armor and with shields.

Bonus Feat or Spells: When a thrall of Demogorgon attains 1st, 4th, 7th, and 10th level, the character gains new spells per day as if he had also gained a level in whatever spellcasting class be belonged to before he added the prestige class, or else he gains a bonus feat of his choice. If the thrall chooses +1 spellcasting level, he does not gain any other benefit a character of that class would have gained (improved chance of controlling or rebuking undead, metamagic or item creation feats, hit points beyond those recieved from the prestige class, and so on) except for an increased effective level of spellcasting This essentially means that he adds the new level to the level of whatever other spellcasting class the character has, then determines spells per day, spells known, and caster level accordingly.

A thrall of Demogorgon is free to choose the bonus feat at one opportunity and the spellcasting level the next time the decision arises, or vise versa. Characters who are not spellcasters must chose the bonus feat.

Scaly Flesh (Ex): A 1st-level thrall of Demogorgon gains dark scaly flesh, which provides a +1 natural armor bonus. At every three levels beyond the 1st (4th, 7th and 10th), this bonus increases by +1. The bonus from scaly flesh stacks with that of natural armor derived from creature type (if the thrall of Demogorgon is a lizardfolk or troglodyte, for example), but not from magical sources such as an amulet of natural armor.
