Skadi the Corrupting Heart

Turning into an Abyssal Hunter in the story is a 6-star Supporter. Her talent enables her to summon a Seaborn, which could extend her attack range and increase the attack of her allies and the Seaborn. This effect would be increased if there is another Abyssal Hunter.


The leading role in the last event and the main character in Rhode Island has finally been added to Standard Headhunting. As a new 6-star Medic,  Kal’tsit is the first Summon and DPS Medic Operator. Her first talent can summon, heal and redeploy Mon3tr. When defeated, her second talent makes Mon3tr stun and deal true damage to enemies.


A 6-star Specialist is the bonus operator that can be obtained for free. As the head of the Rhodes Island Aegir Affairs, her talents enable all Abyssal Hunter operators on the field to recover health points per second and receive less damage from Seaborn enemies. Her second talent increases her attack when attacking enemies lighter than a certain weight.


A 5-star Guard has the talent to increase talent that increases her ASPD based on her lost HP. Her first skill will turn Block into 0, increasing her ATK and making her attack strike twice. Her second skill causes an immediate HP loss and gives her one Shield, and increases her ATK and DEF.
