Focused Mind

Your mind is honed to a razor's edge, and your attention can be split between two areas. You gain the following benefit

• Increase you Intelligence score by 1 point, to a maximum of 20.
• If you attempt to use you action to cast a spell that requires concentration while already concentrating on an existing spell, you can use your bonus action to maintain concentration on both spells simultaneously on each subsequent turns until one of the spell's effects ends, you concentration is lost, or when you use your bonus action for something else.
• Any time you would be forced to make a Constitution saving throw to maintain concentration due to taking damage, the DC equals 10 + half the highest spells’ level, or half the damage you take, whichever number is higher. On a failure, you lose concentration on both spells.
