Honkai: Star Rail Pure Fiction High HP Boss Strategy

To clear high-difficulty Pure Fiction stages featuring massive health pools—such as Part 3 Wave 3 where Hoolay's HP exceeds 78 million—you must shift team compositions away from slow, single-target setups toward high-frequency Area of Effect (AoE) damage, action advance supports, and consistent energy regeneration.

Adapting to Pure Fiction Health Inflation

The primary bottleneck in high-difficulty Pure Fiction cycles is enemy durability. In Part 3 Wave 3, the boss Hoolay features an HP pool of over 78 million, more than double the roughly 30 million health seen in earlier iterations.

Chip damage and low-frequency single-target setups cannot output enough total damage to achieve maximum rewards within the cycle limit. To meet score thresholds:

• Focus on High-Frequency AoE: Deploy damage dealers who hit multiple enemies continuously. Rapid wave clears build energy and stack active stage mechanics faster.
• Eliminate Single-Target Liabilities: Single-target attackers that struggle to clear mob waves efficiently will slow down your overall cycle time, leaving insufficient time to burn down the boss.

Team Composition and Turn Manipulation

Defeating inflated boss health pools requires maximizing the output of every action taken before cycles expire.

• Action Advance Supports: Bring support units capable of pushing your primary AoE damage dealers up the action gauge, granting them multiple turns per cycle.
• Energy Regeneration: Use battery supports to ensure your main attackers can trigger their Ultimate abilities frequently throughout every wave.
• Speed Substat Priority: Optimize relic substats to reach higher Speed thresholds. Taking an extra turn within a cycle window is often more effective than stacking pure Attack power when racing against the clock.

Aligning Buffs and Evaluating Resources

• Utilize Stage Whims: Align your team's burst windows directly with the active stage mechanics (Whims) provided in the current Pure Fiction cycle. Ignoring these passive bonuses makes clearing boss health thresholds significantly harder.
• Evaluate Investment Limits: Overcoming massive HP pools with older or unspecialized units requires significantly higher relic quality and skill trace investment. If your existing roster falls short of clearing the target score, focus resources on broadly versatile support characters or wait for banner options tailored specifically to high-density AoE challenges.
