Honkai Star Rail Phainon: Comprehensive Guide for 2025
Discover Phainon, the powerful DPS in Honkai Star Rail, with unique Coreflame mechanics and transformative abilities that dominate the meta in 2025.
Phainon, also known as Khaslana, has been making waves in Honkai Star Rail since his release in Version 2.6. As the Chrysos Heir carrying the Coreflame of "Worldbearing," this Physical Destruction path character has quickly established himself as one of the most powerful DPS units in HSR phainon meta.
Who is Phainon in Honkai Star Rail?
Phainon comes from Aedes Elysiae, a remote frontier village that now exists only in legends. His real name is Khaslana, and he carries the responsibility of bringing "the first light of dawn to the new world." His memorable quote, "But should dawn have never existed, let the fires of rage burn this body to ashes and transform into the blazing sun of tomorrow!" perfectly captures his fiery determination.
In the hsr phainon trailer released earlier this year, players got their first glimpse of his unique transformation mechanics and devastating combat abilities, which we'll explore in detail below.
Phainon's Unique Gameplay Mechanics
What sets Phainon apart from other characters is his distinctive Coreflame mechanic. Unlike traditional energy systems, Phainon uses Coreflame stacks to activate his Ultimate. These stacks can be accumulated through:
-
Using his Skill (grants 2 Coreflame)
-
Being targeted by ally or enemy abilities (1 Coreflame per targeting)
-
Receiving energy restoration from allies (via his A4 trace)

The Transformation State
Once Phainon accumulates 12 Coreflame stacks, he can activate his Ultimate "He Who Bears the World Must Burn" to transform into Khaslana. During this transformation:
-
All other allies temporarily leave combat
-
All enemies gain Physical Weakness
-
Phainon receives 8 extra turns with speed set at 60% of his base SPD
-
His abilities are enhanced with new "Titans" versions
-
He gains significant ATK and HP boosts
-
He becomes immune to Crowd Control debuffs
This transformation state is what makes phainon Honkai Star Rail's first true "solo DPS" character, capable of handling entire combat sequences without ally support.

Manage Scourge Points: During transformation, try to use Enhanced E Skill (Foundation: Stardeath Verdict) only when you have 4 Scourge points for maximum damage.
-
Time Your Transformation: Consider the enemy's action bar before transforming, as you'll want to maximize damage during the enhanced state.
-
Use Calamity: Soulscorch Edict Strategically: This ability forces enemies to take action while reducing damage to Phainon by 75%, making it excellent for counter-attacking.
-
Plan for Post-Transformation: Allies will be at the same action value they had before transformation, so plan your rotation accordingly.
