6. New Metamagic Feats:Complete Arcane offers a host of new metamagic feats, including Chain Spell (which arcs a spell to a number of secondary targets after affecting the primary one), Repeat Spell (which automatically recasts a spell 1 round later), Cooperative Spell (which boosts the caster level and save DC when multiple casters cast the same spell simultaneously), Transdimensional Spell (which lets a spell affect creatures in coexistent planes and extradimensional spaces), and Nonlethal Substitution (which lets the caster opt to deal nonlethal instead of lethal damage with an energy spell).
5. Sudden Feats: Seven new metamagic feats (Sudden Empower, Sudden Extend, Sudden Maximize, Sudden Quicken, Sudden Silent, Sudden Still, and Sudden Widen) allow the caster to apply a metamagic feat to a spell without prior preparation. What wouldn't your mage give to use a metamagic feat on just one spell at the right time, without preparing it specially, taking up a higher spell slot, or increasing the casting time?
2. Spells, Spells, Spells:Complete Arcane has dozens of new spells -- everything from the basic utilitarian (such as energy immunity or fire wings) to the high-flash, high-damage effects (such as emerald flame fist, fireburst, and flensing).
