Damien

Damien is a human male thief and one of the Adventuring Party (Underdark) group encountered in the Underdark. 
==Gameplay==
This creature will start the conflict invisible and is scripted to use his oil of speed and then Backstab.
Damien will force cast a special innate spell ability (SPIN905.spl) that destroys illusions in a large area as a divination attack, and automatically destroys any creature with a gender of illusion (such as a simulacrum, mislead clone or projected image). A clone protected by Minor Globe of Invulnerability or similar AoE spell protection will be shielded against the spell.
Damien is scripted to strike spell casting classes (especially with backstabbing attacks) above others, including Mage, Bard, Cleric and Druid creatures he can detect.
After a backstab attack he'll quaff a potion of invisibility and make another attack. He will deal quadruple damage upon a successful hit. Somewhat surprisingly, the game didn't assign the thief with weapon proficiency in short sword, which will hamper his THAC0.
==Mod content==
Installation of the Sword Coast Stratagems Mod makes a few changes to this Thief. A default SCS script is provided for smarter tactical behavior and targeting. One pip in short sword weapon proficiency and single-weapon style is assigned.
