MapleStory M Stella Code Guide
팀쿡
This is Stella Code, one of the 2025 WINTER updates.
To briefly explain Stella Code,
“the power created by bringing back together the five constellations scattered by Sol Erda overload”—말 그대로, it is an ability unique to MapleStory M.
Stella Code is made up of 2 parts.
1) The active skill “Constella Core”
2) The passive skill “Star Chorus”
1. Constella Core
This is Constella Core, the active skill.
Right now, only the active skill is available, but buff-type skills also seem to be scheduled for a future update.
The “Serion” needed to enhance Constella Core is generated at a rate of 1 per 1,000 “Serion Flare” obtained.
You use Serion to enhance the skill, and its damage increases based on level.
In particular, every 10 levels also boosts additional effects beyond raw damage, such as Ignore DEF and attack count.
2. Star Chorus
This is “Star Chorus,” the passive skill.
It increases stats such as Max Damage, Physical or Magic Damage, Attack Power, and Final Damage.
The material used to increase these stats is “Serion”
The large-star Upper Chorus allows option reassignment!
The small-star Normal Chorus has fixed options, so option reassignment is not available..
To summarize briefly!
A system called Stella Code was added in the 2025 winter update
It includes active and passive skills, and you can level up those skills with “Serion”
*To unlock Stella Code, you must complete the related level 250 quest “<Authentic> Complete Stella Code.”
**Currently, Serion can be obtained by clearing weekly/monthly bosses.
