How to defeat @SparxiConOfficial in Honkai: Star Rail

Quick answer: To defeat @SparxiConOfficial, use characters with Fire, Quantum, or Imaginary elements. The fight requires you to manage the Live Showdown mechanic, which separates one ally into a sub-field. Clear the enemies in the sub-field quickly to remove the boss's damage reduction in the prime-field. Teams focusing on Elation damage are particularly effective at countering these mechanics.

The Version 4.0 update for Honkai: Star Rail introduces the boss @SparxiConOfficial, an eccentric variation of the character Sparxie located in Planarcadia. This enemy appears during the "No Aha at Full Moon" Trailblaze Mission. Success in this encounter depends on managing a split-battlefield mechanic that isolates your team members and forces you to fight on two different planes simultaneously.

Below are the specific weaknesses, mechanics, and strategies required to clear the encounter.

Enemy Weaknesses and Resistances

@SparxiConOfficial has specific elemental weaknesses that you should target to inflict Weakness Break. The boss also possesses resistance to several other elements, making team composition critical.

The boss has a Toughness pool of 960 (at base levels) and deals Quantum damage.

Key Mechanic: Live Showdown

The defining feature of this fight is the Live Showdown mode. When @SparxiConOfficial casts the ability "Get On the Mic!", the battlefield splits into two distinct planes: the prime-field and the sub-field.

• Separation: One of your characters is selected to enter the sub-field alone, while the remaining three allies stay in the prime-field with the boss.
• Isolation: Characters in the prime-field cannot attack enemies in the sub-field, and vice versa. Support skills can still target allies across planes.
• Damage Reduction: While Live Showdown is active, enemies in the prime-field (including the boss) take significantly reduced damage.

How to Dispel Live Showdown

To make the boss vulnerable again, you must end the Live Showdown state. This occurs when any of the following conditions are met:

1. Victory in the Sub-field: Defeat all enemy units (such as "Aggressive Reading Material" and "Live Stream Assistant") present in the sub-field.
2. Timer Expiry: The Live Showdown countdown in the Action Order reaches zero.
3. Ally Defeat: The character in the sub-field is knocked down.

Strategy and Counters

Manage the Sub-Field Split

Since the sub-field requires clearing waves of enemies quickly, ensure the character sent to this plane has high damage output. If you can influence the selection, prioritize sending your main DPS to the sub-field to eliminate the "Aggressive Reading Material" adds rapidly. Clearing these adds dispels the boss's defensive state, opening a window for your prime-field allies to deal heavy damage.

Utilize Elation Damage

Characters who deal Elation damage are the most effective counters for this fight. Mechanics associated with the Path of Elation can bypass certain targeting restrictions or deal damage in ways that negate the separation penalty of the Live Showdown. An Elation-focused team can ignore much of the complexity of the plane separation.

Interact with Output Ports

The fight includes a mechanic called Friendship Level Adjustment involving "Output Port 1" and "Output Port 2." Attacking these ports adjusts popularity metrics:

• Attacking Output Port 1 increases "Ally Popularity" and advances the port's action.
• Attacking Output Port 2 decreases "Enemy Popularity" and advances that port's action.

Manipulating these ports can provide buffs or Action Advance advantages to your team.
