Concentrated Mind

You can partition your mind to concentrate on multiple spells at once. You can concentrate on a number of spells equal to half your constitution modifier (rounded down) plus half your spellcasting ability (rounded down) (minimum of 2 spells). You can concentrate on the same spell twice (or however many times) as long as it does not target the same creature twice. Due to the immense concentration required to concentrate on multiple spells at once, any constitution save that you make to retain concentration on a spell will be rolled with disadvantage for each additional spell you are concentrating on. For example if you are concentrating on 3 spells you will roll with double disadvantage. If you fail the save you lose concentration on all spells you are concentrating on. Additionally, your face and body language will also appear tense and some smarter opponents may target you because of this.
