World of Sharr
The Adhma Mask is a sacred rite of passage among the Wysers. Grown from the Adhma Trees grown and developed by the Wysers themselves to have Manna enhancing properties. Typically an Adhma Mask is made in the weeks preceeding the Wheel. The Apprentice is given a block of Adhma wood, and must carve from it a mask that he feels represents himself. This mask is then to be worn for the first time during the Wheel.
The mask always gives an extra 2 manna to the character’s max manna when worn that is used first. This manna recharges daily like the Wyser’s. However, the true power of an Adhma mask is found in its ability to slowly drain unnoticable amounts of manna from its possessor and the surrounding environment at roughly a rate of 1 point for every day to a maximum of 5 that can be drawn from when worn.
