Geas Spirits
-4 Charisma. With so many of their memories gone, they find it hard to remember how to relate properly to the not-yet-dead.
Geas Spirits are Undead (with all the advantages and disadvantages of that type) and match their patron's alignment in subtype.
Turn Resistance +4.
Momentary Intagibility (Su). For one round each day, a Geas Spirit may make himself and any equipment carried by him Incorporeal.
Light Sensitivity.
Geas Spirits are automatically treated as being Commanded by clerics of their Patron that have 4 or more HD than themselves. They are automatically treated as Bolstered while within 30' of a cleric of their Patron deity.
Mission (Su). A Geas Spirit knows at all times where the ultimate objective of their mission is and what exactly their objective is, but has no other information regarding their mission. For example, a Geas Spirit brought back to destroy the Last Pillar of Agritha will know exactly where it is in relation to himself, but without Knowledge (Geography) the spirit may not even know which country it is in. Moreover, the spirit doesn't know anything about the Pillar's surroundings, if it is guarded, how hard it will be to get there, or what is needed to do in order to destroy it once he or she is there without further research.
