To sum up
Barbara, a 4-star water magic weapon character. The only ones with their own damage mechanism are A, heavy hit and falling attack. Both E and Q only have healing capabilities and no output mechanism.
The water ring generated by casting E will apply a weak water attachment to the enemies around itself every 2 seconds. It will automatically restore the health of the character currently on the field every 5 seconds. It will also apply a water attachment to the character (if encountering ice). The environment or enemies that can deal ice element damage will be frozen. Enemies that deal fire element damage will be evaporated. The same goes for other elements... This is the reason why it is called an "inner ghost"). If Barbara is stationed on the field and the water ring exists, hitting an enemy with Barbara's A and heavy attack will restore the health of the entire team. The amount of healing generated by the heavy attack is 4 times that of A.
Casting Q simply restores 1 health to all characters in the team. It is the character with the highest instantaneous healing multiplier among current healing characters, and is also the only current 4-star character who has an animation effect when casting Q.
To cultivate Barbara, it is highly recommended that the character exceeds level 60 to unlock [Inherent Talent·Encore]: When your character on the field obtains elemental crystal balls or particles, the duration of the water ring can be extended by up to 5 seconds. It can effectively reduce the vacuum period of E and is more practical.
Since there is no special output ability, it is basically recommended to train him as a therapeutic support. When there is no established team, if the team lacks a healer or a weak background role, Barbara can be considered to join the team for support.
Of course, the true love resident type can be applied to the three-person Naxingjiu system and the armed team system. Secondly, everything can be C, and it can also use its own high multiplier (Barbara’s critical hit multiplier ranks first among all magic weapon characters at present). 3) Heavy attack team, heavy attack flow evaporation team, most of the other teams can replace Xinhai.
