Residing in Mortis' Courtroom, Mortis is the final boss of the Sea of Shadows region. To access Mortis' Courtroom, complete the quest Across the Sea of Souls and give 1 Coin to the Ferryman to transport you across the Sea of Souls.
During phase I of the battle, players must defeat Skeledragon., Mortis' Bodyguard will also appear to challenge you in battle.
Skeledragon and Mortis
Killing Skeledragon will initiate phase II, and the arrival of Skeledragon and Mortis, and now is when the main challenge begins. Mortis' Bodyguards will continue to enter the courtroom.
The team goal is to defeat Mortis before 1000 hateful souls reach the center seal. If a Malicious soul or a Malevolent soul enters the seal, a soul counter in the top right corner of the screen will tally the additional soul. If the soul count reaches 1000, all player in the arena will face an inevitable death and Mortis revives complete health.
Negation puddles will drop within the courtroom; players in the puddle will not be able to use any skills, and must walk outside the puddle before being able to use skills.
Stepping into the center seal will cause continuous andermagic damage and slows movement.
Teams must balance players between attacking Mortis and preventing high number of souls from reaching the center seal.
