Congratulations on being of level to use
Call of Bones! Unlike the previous versions of the Lich spells, this one will make you into a skeleton. The skeleton illusion modifies your faction with different NPCs around the game world. Generally, this will not help you with good people.
However, it is strong enough to take an Iksar that is KOS in Neriak up to Amiable with most factions in Neriak.
Be sure to play it safe and spy out what areas are safe for you while using Call of Bones. It is just worth knowing that this spell does provide you with the ability to open up some merchants and areas. "
