Arcanaloth sub-race

About
The arcanaloth are the record keepers of yugoloths. As yugoloths go, they are a civilized breed. They are Neutral Evil aligned and can speak and write any language.

An arcanaloth appear as a robed human with the head of a fanged jackal or war dog.

Combat
The physical attack of a powerful arcanaloth consists of a claw and bite routine. They enjoy inflicting pain and torment with their claws.

All arcanolths commonly memorize destructive spells but they keep a wise eye on their escape and defensive spells for good measure. They are extremely intelligent and use their spells to their best advantage. In general, these creatures avoid hand-to-hand combat.

Arcanaloths are harmed only by magical weapons of great enchantment. They are immune to mind affecting spells. They may never be surprised while on lower planes. They can only be permanently destroyed while on Gehenna; when this happens, its accumulated knowledge travels to the Tower of the Arcanaloths to be absorbed into the racial memory of all arcanaloths.
