Dual-focused

The ability to cast atleast one spell.

Countless hours have been spend training your mind to maintain focus on concurrent incantations, taxing a the process may be.  

• If you attempt to cast a spell that requires concentration while already concentrating on an existing spell, you canmaintain concentration on both spells simultaneously. You must spend a standard action each subsequent round on maintaining this concentration or lose concentration for both spells.
• At the end of each turn where you have two spells uou are concentrating on, you must make a Consitution saving throw (DC equels 10 + the number of complete rounds you've been concentrating on two spells). On a failure, you lose concentration for both spells. You can drop concentration on one of your spells during your turn as a free action to avoid this saving throw. = Any time you would be force to tmake a Constitution saving throw to maintain concentration due to taking damage, the DC equels 10 + both spells' levels combined or half the damage you take, whichever number is higher. On a failure, you lose concentration on both spells.
