My Fire Mage has Plasma Mastery (RoCo. III), Light's Creations (RoCo. V), Earthfires (Guild), Holy Fires (Guild), Speech Mastery (own list), Sun's Heart (Guild) and Explosives (AlC) as his base lists. Since there are seven of them, he may only choose three others as base lists (with Blood Law highly recommended). In addition, he may develop Glass Mastery (RoCo. V) as a prosaic spell list. With all of these, he has mastery over eight concepts associated with his elements (heat, light, lava, plasma, explosions, glass, speech and blood) and even nine if one uses the radiation critical table for the light spells (radiation).
He uses the Magician's skill costs and profession bonuses, but for the following skills: Cookery (1/5), Signalling (1/3), Alchemy (1/3), Frenzy (4/8), Crafting (1/4), Public speaking (1/5), Duping (2/4).
Experience proves that his power level balances well with the other elemental mages —by that I mean the Wood Mage, the Earth Mage, the Metal Mage and the Water Mage— and he plays his appropriate role amidst them.
