Queen Persephone is one of the best tanks in the game. If not the best. The queen of the underworld only needs to take the field to do her job: reduce the opponent's maximum HP at the end of each turn, place the seed that records the damage, increase the HP of our allies, and when the time comes, unleash the damage on the enemies.
She is an excellent unit, but she has some problems in the current meta. As a tank, she protects the team by absorbing damage, which is very good, but not so much with so much area damage, which can cause her premature death. Also, there is a lot of control, which can prevent her from activating her second skill at the right time. But the most difficult thing is that we have to invest a lot of skill books to get her full potential.
