Multi-Tasker

You have trained your mind to focus on multiple tasks at a single time with uncanny precision. You gain the following benefits:

• On your turn, you gain the ability to use an additional bonus action. You cannot perform the same bonus action twice on the same turn. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
• You can maintain up to two Concentration spells at a single time. When you are Concentrating on two spells at the start of your turn, you lose your reaction and bonus action for that turn. When maintaining two Concentration spells, at the end of each of your turns you must make a DC 10 Constitution saving throw to maintain your concentration. In addition to this, whenever you take damage and are forced to make a Constitution saving throw to maintain your Concentration on two spells, you do so at disadvantage, losing Concentration on both spells on a failure.
• You are able to train multiple abilities or proficiencies at a single time. (XGE Ch.2 Pg.134)
