Myrrh

Myrrh is a magical herb that aids summoning rituals. A dram with cinnamon and olive oil makes Fragrant Oils, and seven drams with frankincense make the Fumes of Favorable Aspect; both give +1 saves when summoning or evoking hostile beings. Necromancers also use 13 ounces of it to embalm a corpse over a week, the first step in raising a sahu, or mummy. It grows in fields and costs 5 G.P. per dram.
