A is for Adramelech

The most glorious fiend in all of the Hells (at least in his opinion), Adramelech is speaker of the fiendish council. A devilish fashionista, he is also coordinator for the highest infernal nobility. He is a vain, but intelligent creature, with a razor sharp wit. While he believes himself to be above the mortal realms, he will occasionally answer an occultist's call.

Adramelech's mastery of language and wit is his most dangerous weapon. Using infernal magic he can actually craft an insult so vicious that a target within earshot must making a saving throw or take 2d6 damage. He can also use his words more insidiously, using them to cast Charm Monster 1/day and Charm Person an unlimited number of times. Though it is vain, he has a glorious aura that protects him. In order to attack Adramelech, a mortal must first make a successful saving throw.  Even if struck, he is immune to most damage. He only takes normal damage from magic, magic weapons, and sewing and grooming implements (such as needles, razors, and shears).
