Quantum Element Characters
Quantum Element CharactersEvery Quantum element character in Honkai: Star Rail — with the best builds, teams, light cones and relics, kept up to date with the meta.
Last updated: 31/07/2026

The figures on this page come directly from gamevika's internal game data store (counted/read straight from the real records), not an estimate or copy from elsewhere.
Honkai: Star Rail has NO Genshin-style elemental reaction system. An element only determines the damage type dealt and the Weakness Break debuff applied — weaknesses are a property of each individual enemy, not a fixed element-vs-element chart.

Three things players get wrong
- Honkai: Star Rail has NO Genshin-style elemental reaction system. An element only determines the damage type dealt and the Weakness Break debuff applied — weaknesses are a property of each individual enemy, not a fixed element-vs-element chart.
- Break Effect is nearly USELESS on Ice characters: Frozen carries no follow-up DoT to multiply against, it only skips the enemy's turn (with their next turn's action gauge advanced 50%) — whereas Physical/Fire/Wind/Lightning all apply an uncapped Break Effect-scaling DoT. Stacking Break Effect on an Ice DPS is close to wasted substats.
- An enemy that is NOT weak to the element being used has a baseline 20% DMG RES against that element; an enemy that IS weak to it has 0% RES. Some enemies stack extra RES (≥40%) on top of that 20% baseline. This is why the same character's damage swings sharply between a matching-element enemy and a mismatched one, even with no reaction chart involved.

Toughness reduction per hit — FIXED
Does NOT matter
ATK · CRIT Rate/DMG · Own Max HP · Enemy's stats/debuffs
DOES matter
ONLY the "Weakness Break Efficiency" buff
DMG dealt AT THE MOMENT of Weakness Break
DOES matter
Break Effect · Character's level · Enemy's DEF · Enemy's level · Enemy's max Toughness
Does NOT matter
ATK · Own DEF · Own Max HP · CRIT Rate/DMG · Which move type triggered the break
Many players over-invest in ATK/CRIT for a break-focused character — neither affects toughness reduction or break DMG. Only Break Effect + character level actually matter.
