The Sky Titan boss (Aquila) is one of the most challenging bosses in Honkai Star Rail, introduced in the 3.3 update during the Flame-Chase Journey in Amphoreus. This boss fight tests a player’s mechanics and team composition knowledge, featuring multiple phases with distinct challenges.
In this guide, we will break down each phase of the fight, discuss optimal strategies, and provide recommendations on how to build your team to defeat this formidable foe.
Sky Titan Boss Weaknesses
Players should exploit its elemental weaknesses to efficiently damage the Sky Titan (Aquila). The Sky Titan is vulnerable to Physical, Ice, and Quantum damage. Its summons also have specific elemental weaknesses that can help reduce the fight’s difficulty.
Choosing characters specializing in these elements will significantly aid in breaking the Titan’s defenses and secure victory.
Phase 1: Temperature Mechanic
In the first phase, the Sky Titan raises the battlefield temperature, inflicting burn damage on your team over time. As the temperature increases, the more Burn damage your characters will take. However, this also boosts your outgoing damage, making it a double-edged sword.
Strategy:
- Healers over Shielders: A strong healer is essential to counteract the Burn damage during this phase. Shielders will not provide sufficient protection against the heat.
- Maximize Damage: The increased temperature boosts your damage output, so time your powerful attacks when the temperature is high.
- Manage Turn Order: Pay close attention to the turn order, as excessive temperature buildup can quickly overwhelm your team.
- Using healers like Hyacine or Gallagher will be key to surviving this mechanic.
Phase 2: Thundercloud Mechanic
The second phase introduces the Thundercloud mechanic, where the Sky Titan accumulates Thundercloud stacks. After several turns, the boss will unleash a devastating attack with significant damage. While Thundercloud does not inflict damage directly, the final strike can be catastrophic if not managed properly.
Strategy:
- Defeat Summons Quickly: Focus on eliminating the Daythunder Ravens and Twig/Shoot of Hundred Eyes as quickly as possible to reduce the Thundercloud stacks.
- Weakness Break: Once all Thundercloud stacks are cleared, the Sky Titan will enter a Weakness Break state, allowing for heavy damage to be dealt.
- AoE Attacks: Multi-target or AoE attacks are beneficial for clearing summons and controlling the Thundercloud stacks.
- Characters that excel in AoE abilities, such as Yunli or Blade, are recommended here.
Phase 3: Black Tide Mechanic
The final phase of the fight introduces the Black Tide mechanic. As the Sky Titan transforms into Decimator, Karma of Daythunder, a Black Tide bar begins to fill. When it reaches a certain threshold, the Titan will unleash an attack that inflicts Rot, reducing the max HP of all characters for the rest of the fight.
Strategy:
- Defeat the Summons: To control the Black Tide, focus on defeating the two summons (Languid Ethmoid Bone and Dried Lacrimal Bone). This will slow down the Black Tide meter and reduce its threat.
- Support Buffs: Use characters like Hyacine, who can provide buffs to max HP and healing, countering the effects of Rot.
- Burst Damage: Save your most powerful attacks for the Weakness Break moments in this phase, where you can deal significant damage.
- Effective healing and high burst damage during Weakness Breaks are essential for surviving this mechanic.
