Magic of Faerun

Name Prerequisites Benefit
Attune Gem Intelligence 13+, Craft (gemcutting) skill, arcane spellcaster level 3rd+.  
Augment Summoning Spell Focus (conjuration). Each creature you conjure with any summon spell gains a +4 enhancement bonus to Strength and Constitution for the duration of the spell that summoned it. 
Energy Substitution Any other metamagic feat, Knowledge (arcana) 5 ranks. You choose one type of energy: acid, cold, electricity, fire, or sonic. When employing a spell with the acid, cold, electricity, fire, or sonic designator, you can modify the spell to use your chosen type of energy instead. The altered spell uses a spell slot of the spell's normal level. The altered spell works normally in all respects except the type of damage dealt. 
Eschew Materials   You can cast any spell that has a material component costing 1 gp or less without needing that component. (The casting of the spell still provokes attacks of opportunity as normal.) If the spell requires a material component that costs more than 1 gp, you must have the material component at hand to cast the spell, just as normal. 
Reactive Counterspell Improved Counterspell, Improved Initiative.  
Spell Girding    
Spell Thematics Arcane spellcaster level 1st.  
Spellfire Wielder    
Widen Spell   You can alter a burst, emanation, line, or spread shaped spell to increase its area. Any numeric measurements of the spell's area increase by 100%. A widened spell uses up a spell slot three levels higher than the spell's actual level. Spells that do not have an area of one of these four sorts are not affected by this feat.
