Of Two Minds

You have learned to divide your attention between two spells simultaneously.

• If you attempt to cast a spell that requires concentration while already concentration on an existing spell, you can maintain concentration on both spells simultaneously so long as the combined level of the two spells does not exceed your proficiency bonus.
• If you take damage during this time, you must make a concentration check for each spell individually.
• At the start of each of your turns where you have two spells you are concentrating on, you must make a constitution saving throw (DC equals 8+both spells’ levels combined). On a success, you maintain concentration on both spells. On a failure, you lose concentration on both spells.
