Battlecry (EFA - B)

When you cast battlecry, you and creatures you choose within range who can see and hear you gain a burst of confidence and combat prowess. The next attack made by an affected creature is made with advantage, and on a hit gains a +2 bonus on the damage roll, provided
the attack is made before the end of your next turn.

In addition, an ally who is currently suffering the charmed or frightened conditions can use its reaction to attempt a new saving throw against that effect with advantage.

Finally, you regain one use of your bardic inspiration.
