Effortless Concentration

Maintaining simpler spells has become easy through practice. As a result you may split your focus cross several spells simultaneously.

You may maintain concentration on a second spell of a level as high as 3 levels lower than the highest level spell you can cast. When you gain access to 6th level spells you may maintain concentration on a third spell of a level as high as 6 levels lower than the highest level spell you can cast.

Cantrips count as 0th level spells for this purpose.

Maintaining concentration on multiple spells makes it more difficult to maintain that concentration. For each spell you are concentrating on beyond the first the concentration DC is increased by 5. If you fail your concentration save while maintaining multiple spells you lose concentration on all of them simultaneously.
