Certain abilities and actions require concentration to maintain their effects.
While concentrating, you can still move, act, and use other abilities, but you cannot maintain concentration on more than one ability at a time.
If you take damage while concentrating, you must make a Constitution saving throw to maintain your focus. The DC for this save is either 10 or half the damage you received, whichever is higher. Failing this save results in the loss of concentration, ending the effect of the ability prematurely.
