Concentration Mastery

After many years of studying and meditation. You have gained mastery over your head spaces.

This feat allows one extra Concentration spell with out penalty. However any more past that will cause a negative 3 to con roll per spell. On failed roll you lose last spell cast until you have lost them all. If you roll a nat 1 you lose all spells and take 1d4+1 psychic damage.

You also gain advantage on Concentration rolls for spell use only. But while concentrating on more than one spell you have disadvantage on dexterity and strength rolls.
