Shadow lord (shadowdancer)

Dark and dangerous creatures from the dreaded lower planes, shadow lords never hunger or thirst, attacking only to satisfy their desire to do evil.

Special abilities
A shadow lord has damage reduction 30/+2; 100% immunity to cold, electrical, and fire damage; immunity to knockdown; and the usual undead immunities to critical hits, death magic, disease, level drain, ability drain, mind-affecting spells, paralysis, poison, and sneak attacks. Furthermore, this creature in incorporeal (which implies 50% concealment) and has turn resistance +10.

A shadow lord can cast darkness once per day at caster level 10.

Due to the presence of a special AI script (namely ), this shadow lord can forgo its regular attack to conduct a shadow attack. The intended chance of using a shadow attack is 1-in-3, checked each combat round, but a bug in the script prevents a shadow lord from making use of its shadow attack once it uses its regular attack (until the current combat ends).
