The Pyramid Of Calulos

While inspecting The Pyramid Of Calulos may role an Arcana Check DC 22. On a fail you cannot attempt to do so again for a week. On a success you may choose a Necromancy spell of a level you know and add it to your spell list, This spell does not count against your spells known. The inspector may not use The Pyramid Of Calulos for another 101 years.
It burned the knowledge in my mind.
