# Phainon (Honkai: Star Rail)
**Phainon**, real name Khaslana, is a playable character in the turn-based role-playing game *Honkai: Star Rail*, developed by HoYoverse. He is a 5-star Physical attacker on the Path of Destruction, introduced in Version 3.4 "For the Sun is Set to Die" on July 2, 2025[1](https://www.pockettactics.com/honkai-star-rail/phainon) • [2](https://www.hoyoverse.com/en-us/news/157426). In the game's story, he is a Chrysos Heir carrying the Coreflame of "Worldbearing" from the fallen village of Aedes Elysiae on the planet Amphoreus, where the Trailblazer meets him upon arrival[2](https://www.hoyoverse.com/en-us/news/157426). His defining gameplay mechanic is a two-form system in which his Ultimate transforms him into Khaslana, removes all teammates from the field, and lets him fight alone as a boss-like entity[3](https://www.prydwen.gg/star-rail/characters/phainon).

## Story and identity
Phainon is introduced as a warrior from Aedes Elysiae, a remote frontier village now lost to history, and is among the first Chrysos Heirs to extend goodwill to the Trailblazer in Amphoreus[2](https://www.hoyoverse.com/en-us/news/157426). His parents are Hieronymus and Audata, both deceased[4](https://honkai-star-rail.fandom.com/wiki/Phainon). He carries several titles in-game, including the Nameless Hero, the Deliverer, the Blazing Sun, the Flame Reaver, the Throne of Worlds, and the Vessel of Destruction[4](https://honkai-star-rail.fandom.com/wiki/Phainon).
The character's real name is revealed as Khaslana over the course of the Amphoreus story arc[4](https://honkai-star-rail.fandom.com/wiki/Phainon). Version 3.4 centers on the Trailblazer venturing into Aedes Elysiae to trace Phainon's journey from his rise as a warrior to joining the Flame-Chase and becoming the person he is today[2](https://www.hoyoverse.com/en-us/news/157426).
## Gameplay mechanics
Phainon uses a unique two-form system. His Ultimate, "He Who Bears the World Must Burn," requires 12 points of a resource called Coreflame rather than standard Energy, with up to 3 excess points accumulating beyond that limit[5](https://www.pcgamer.com/games/rpg/honkai-star-rail-phainon-materials-kit/). Coreflame is generated by using his Skill, by being targeted by ally or enemy abilities, and through bonus abilities tied to receiving healing or energy regeneration from teammates[5](https://www.pcgamer.com/games/rpg/honkai-star-rail-phainon-materials-kit/).
Upon transforming into Khaslana, Phainon deploys a [Territory](https://www.edgepedia.org/territory) in which all teammates become Departed and cannot take action, while all enemies gain a Physical Weakness[3](https://www.prydwen.gg/star-rail/characters/phainon). Khaslana gains 8 extra turns at a fixed Speed equal to 60% of Phainon's base Speed[5](https://www.pcgamer.com/games/rpg/honkai-star-rail-phainon-materials-kit/). During this state he is immune to Crowd Control debuffs and fatal damage, restores HP after attacking, and cannot use his Ultimate[5](https://www.pcgamer.com/games/rpg/honkai-star-rail-phainon-materials-kit/). After the Transformation ends, all allies' Speed increases by 15% for one turn[5](https://www.pcgamer.com/games/rpg/honkai-star-rail-phainon-materials-kit/). Prydwen describes him as a solo-field hypercarry designed to play without a sustain, a rarity among the game's characters[3](https://www.prydwen.gg/star-rail/characters/phainon).
## Release and availability
Phainon's debut banner ran in the first half of Version 3.4 alongside reruns of Tribbie, [Sunday](https://www.edgepedia.org/sunday-honkai-star-rail), and [Sparkle](https://www.edgepedia.org/sparkle-honkai-star-rail)[1](https://www.pockettactics.com/honkai-star-rail/phainon). He received a rerun from November 26 to December 16, 2025, paired with Cipher and Mydei[6](https://www.pcgamer.com/games/rpg/honkai-star-rail-banner-next-current/), and another from June 24 to July 14, 2026, paired with Cyrene[6](https://www.pcgamer.com/games/rpg/honkai-star-rail-banner-next-current/).
His ascension requires 15 Ethereal Omen, 15 Echoing Wail, 15 Eternal Lament, 65 Invasive Clot, and 308,000 credits, with trace upgrades costing a further 3 million credits and 8 Tracks of Destiny among other materials[5](https://www.pcgamer.com/games/rpg/honkai-star-rail-phainon-materials-kit/). At level 80 his base stats are 582.12 ATK, 703.39 DEF, 1436 HP, and 94 SPD[7](https://starrail.honeyhunterworld.com/phainon-character/?lang=EN&ver=3_7_52).
## Design and reception
Phainon bears a striking resemblance to Kevin Kaslana from *Honkai Impact 3rd*, including his real name, and is widely treated as an expy (a character deliberately modeled on a character from another work) of that character[8](https://honkai-star-rail.fandom.com/wiki/Phainon/Lore) • [1](https://www.pockettactics.com/honkai-star-rail/phainon). The casting reinforces the parallel: Phainon's Chinese voice actor Qin Qiege (秦且歌) and Japanese voice actor Hino Satoshi (日野 聡) both voice Kevin Kaslana in *Honkai Impact 3rd*, with Yoon Yong-sik (윤용식) voicing him in Korean[1](https://www.pockettactics.com/honkai-star-rail/phainon) • [4](https://honkai-star-rail.fandom.com/wiki/Phainon). Multiple in-game characters refer to him as the "Deliverer" (Chinese: 救世主), echoing Kevin Kaslana's codename "Deliverance"[8](https://honkai-star-rail.fandom.com/wiki/Phainon/Lore). Guide sites have ranked him as a top-tier carry as of Patch 4.2, citing his self-sufficient solo-field design[9](https://www.guarchives.com/en/hsr/characters/phainon).
