This alchemical creation resembles nothing more than a lump of hard green material and is a by-product of an alchemist’s failed attempt at converting a turnip into gold. However, it was discovered that this material could be used effectively as a replacement for certain other materials in spell casting as material components.
Specifically, mage green can be used in place of any precious metal or precious stone (or mixture of the same) up to a 500 gp value. The nugget of mage green is consumed upon the casting of a spell. The caster’s hands are colored with a fine green coating which is impervious to any type of mundane or magical cleansing. The coloring will wear off naturally in 1d6 days. While a caster’s hands are discolored by mage green, no additional nugget of mage green may be successfully used. If a caster attempts to use a nugget of mage green while his hands remain discolored by a previous use, the new nugget is consumed, an additional 1d6 days are added to the duration of the discoloration of the caster’s hands, and the attempted spell fails.
Prerequisites: Craft Wondrous Item, polymorph any object, Craft (alchemy) 5 ranks. Cost to create: 450 gp, 5 XP, 1 turnip, 2 days.
