Superior Concentration

You've trained your mind to a razor-sharp point, and have the ability to maintain concentration on two spell effects at once. However, you suffer the following penalties while concentrating on two effects:

• You make Concentration checks for both spells with disadvantage.
• You must use your bonus action on each of your turns to maintain concentration on the secondary effect. If you do not, the last concentration spell you cast end.
• Creatures have advantage on saving throws against effects caused by either of the two concentration spells.
