 The main challenge of clearing the Grave of Curse lies in the boss reducing the team's Max HP when dealing HP damage. The team's survival pressure rapidly increases as Max HP decreases. Therefore, it is highly advisable to deploy heroes who can grant AOE shields to prevent HP damage from the boss.
Since the boss gains a significant damage boost after casting [Rage of Blood], it is crucial to deploy heroes with Buff Dispelling/Buff Prohibition to counter it in time.
At difficulty 9 and above, in addition to dispelling 1 buff, [Punishment of Blood] deals additional damage to targets without buffs. Therefore, it is best to deploy support heroes who can provide multiple buffs.
 Summary: This is a lineup built around S1 Lightning-Radiance Affinity. Activate Iola's and Nathaniel's ultimate skills before the boss casts its damaging skills; Attack Penalty inflicted on the boss and AOE shields granted to the team will significantly reduce the boss's HP damage. Even if the team sustains some HP loss, Garius and Nathaniel can promptly restore HP with their AOE healing capabilities. Don't forget to use Grover's ultimate skill right after the boss casts [Rage of Blood] to perfectly dispel two buffs at the same time.
 Summary: Felosia can significantly reduce the difficulty of clearing the Grave of Curse. She can not only provide substantial shields for the entire team but also grant Defense Up and Damage Reduction to make them extremely durable. Pairing her with Vinyara, who can dispel all enemy buffs, allows the team to counter various boss skill mechanics. Premtsa, with remarkable standalone combat capabilities, delivers substantial damage for the team. Finally, select a healer and a tank based on Elemental Affinity to ensure ample team survivability.
