Sunday Phase 1 Strategy

Master Sunday Phase 1 in Honkai: Star Rail. Learn the optimal strategy for this challenging encounter to secure victory and progress.

Confronting Sunday in his first phase requires a strategic approach focused on sustained damage and efficient debuff management. Sunday's initial attacks often involve applying the 'Melancholy' debuff, which can significantly reduce a character's ATK and DEF. To counter this, prioritize bringing characters with strong cleansing abilities or those who can apply buffs that mitigate debuff effects. A team composition featuring a strong Preservation or Abundance character capable of dispelling debuffs, such as Luocha with his healing and debuff removal, or Bailu with her revival and healing, is highly recommended. For damage, characters like Seele, who can take advantage of weakness breaks with her Resurgence ability, or Jing Yuan, who can deal consistent AoE damage with his Lightning Lord, are excellent choices. The key is to maintain consistent pressure while ensuring your team remains healthy and free from debilitating debuffs. Pay close attention to Sunday's attack patterns; he often telegraphs his more powerful abilities, giving you a window to reposition or prepare defensive measures. Breaking his Toughness bar is crucial, as it interrupts his actions and provides a valuable opportunity to unleash your most powerful attacks. Aim to break his Toughness with characters who exploit his weakness, typically Lightning or Wind damage, to maximize the duration of the stun and damage window. Avoid bringing teams that rely heavily on buffs that can be dispelled by 'Melancholy', as this will significantly hinder your damage output.

A common mistake in this phase is focusing solely on offense without adequately addressing the 'Melancholy' debuff. This can lead to a slow, drawn-out fight where your team is constantly weakened, making them vulnerable to critical hits. Ensure your healer is not only capable of healing but also of cleansing. If you lack a dedicated debuff cleanser, consider equipping Light Cones that offer team-wide buffing or debuff resistance. For example, a Harmony character like Bronya, while primarily a buffer, can also advance an ally's turn, allowing them to act sooner and potentially cleanse themselves or be cleansed by a support. The objective in Phase 1 is to efficiently deplete Sunday's health while minimizing the impact of his debuffs, setting up for a smoother transition into Phase 2. Do not underestimate the importance of Weakness Break. Exploiting Sunday's weakness to Lightning or Wind damage can prevent him from unleashing his ultimate ability, which can deal massive damage to your entire team. Conserve your Skill Points where possible, but do not hesitate to use them to maintain buffs or heal when necessary. The goal is to reach Phase 2 with as many resources (Skill Points, Ultimate charges) as possible.
