Geomancy -- magery/fighter additional skill that concentrates on all earth/metal based spells and effects. Includes specialized elementals (various ore and gem ones), more powerful rock walls, stone forms, and for fighters, use of stone weaponry with special moves and bonuses and reduction of damage from "earth based" creatures. Also gives physical resist based on skill, with 100 being 60 physical. And allows tamers to tame earth-based elementals and creatures at 100(with standard taming). Immune to blood-based effects and blades.
Aeromancy -- Similar to Geomancy, but concentrates on air based spells and effects, including a special teleportation by dust-devil (non-spell based), significant increase in parry and other defensive skills usefulness. All energy weapons add lightning hit chance automatically at 80 skill. Allows taming of air based elementals and creatures at 100(with standard taming). Energy resists becomes 60 at 100. Immune to stat-lessening effects.
Pyromancy -- Concentrates on fire based spells and effects. Most fire-based spells increase in power, and walls of fire become much larger and last much longer. However, cold based spells are 1/2 power and duration. Use of all fire weaponry adds fireball or burning hands type effects automatically at 80 skill. Fire resist is 60 at 100. fire elementals and creatures can be tamed at 100 (with standard taming). Fire-based spells do healing, not damage but cold-based double damage.
Brumalmancy -- Cold based spells and effects. All cold based powers are doubled, but fire-based are halved. All cold weaponry adds cold-blast ability at 80 skill. Cold resists 60 at 100. cold elementals and creatures can be tamed at 100(with standard taming). Cannot be paralyzed or held and cold based attacks do no damage, but fire based do double damage.
Miasmanancy -- Concentrates on poison-based spells and effects. All poison weaponry adds +2 to poison level if inflicted at 80 skill, +3 at 100 skill, but normal poisoning rates. Poison resists 60 at 100. all poison-based creatures can be tamed at 100(with standard taming). Cannot be poisoned, and poison-based attacks actually heal. Physical attacks on character are at 1.5x damage.
As for wrestling, either change gloves to include many of the standard weapon mods (and remove resists) or add new gloves that are only wearable by wrestlers that are "weapon" gloves.
