Velithuu

The Velithuu is a unique demon found in the Watcher's Keep - Baatezu (AR3004) area.
==Gameplay==
The creature uses the Frost Salamander sprite as it's animation.
This demon has the racial enemy against Human opponents, a therefore receives a 4 point THAC0 and damage bonus.
The creature has all the usual immunities of demons and can also See the invisible.
The creature's AI primarily makes the demon fire it's shortbow at the closest target over 10 feet distant. 
Bow fire is rapid with a good degree of skill, and an endless supply of ammunition is available for the equipped Shortbow of Gesen.
If forced into melee combat by an opponent (achieved by getting into melee range and staying close to the demon) - then the creature switches attack weapons. The demon's slashing melee attack can Poison the target, but a saving throw is allowed. 
The Velithuu can cast three Wizard spell types as shown on the InfoBox. 
==Notes==
The potential use of Spirit Armor by the demon is actually counterproductive to the demon's defense, other than a saving throw bonus. It might even end up damaging itself after casting it.
==Mod content==
The Sword Coast Stratagems mod makes no special changes to this creature apart from adding immunity to Entangle and Webbed effects.
