TL;DR
- Dust of Enlightenment rerolls substat distributions on max-level 5-star artifacts with guaranteed minimum enhancements
- Hallowed Exegesis system provides progressive improvement tiers with Advanced and Decreed Reshape options
- Acquire through Stygian Onslaught events, battle pass rewards, and version update free gifts
- Strategic usage prioritizes artifacts with correct main stats and 3-4 viable substats
- Resource planning essential – save for high-value artifacts rather than experimenting randomly

Artifact optimization represents the cornerstone of character building in Genshin Impact, serving as the primary method for enhancing combat capabilities beyond innate character attributes. The introduction of Dust of Enlightenment in version 5.7 marks a significant advancement in artifact refinement systems, offering players unprecedented control over substat distributions. This revolutionary item enables targeted redistribution of enhancement values across existing substats, fundamentally changing how players approach endgame gear optimization.
Dust of Enlightenment functions as a specialized reroll mechanism that redistributes enhancement values among minor affixes on fully leveled 5-star artifacts. For instance, an artifact displaying 2 Defense upgrades, 1 Critical Rate enhancement, and 0 Critical Damage improvements can be transformed through Dust of Enlightenment application into a configuration featuring 0 Defense upgrades, 2 Critical Rate enhancements, and 1 Critical Damage improvement. This process maintains the original substat types while reallocating their enhancement levels according to player-designated priorities.
Critical to understanding this system: the selected priority affixes receive guaranteed minimum of 2 total enhancements during standard reshaping. Additionally, players retain selection authority between original and rerolled stat distributions post-enhancement, eliminating the risk of downgrading valuable artifacts.

The Hallowed Exegesis system introduces progressive improvement mechanics tied to individual artifact usage. Each Dust of Enlightenment application grants one Hallowed Exegesis point to the targeted artifact. Accumulating six points unlocks Advanced Reshape functionality, guaranteeing minimum three enhancements for prioritized substats. This advanced tier can be utilized twice per artifact, requiring twelve total Dust applications for both uses.
Reaching sixteen Hallowed Exegesis points activates the pinnacle Decreed Reshape option, ensuring four confirmed enhancements minimum for selected affixes. This safety net guarantees top-tier artifact outcomes after significant investment, protecting players from extended unfavorable RNG sequences.
Dust of Enlightenment ranks among Genshin Impact’s most scarce enhancement resources, with acquisition currently limited to three primary channels. The Stygian Onslaught limited-time event serves as the most reliable source, typically offering multiple units through completion rewards and challenge objectives. Battle pass progression provides another consistent source, with premium tiers granting access to this valuable commodity.
Version 5.7 launch celebrations include complimentary distribution through in-game mail, providing two free Dust of Enlightenment units simply for logging in during the update period. This distribution pattern suggests future version updates may continue offering initial allocation incentives, though players should verify each patch’s specific reward structure.
Seasoned players recommend prioritizing Stygian Onslaught event completion, as these time-limited opportunities often yield the highest Dust quantities. Battle pass acquisition proves more consistent but requires financial investment, making it suitable for dedicated players seeking regular access. The free version update gifts serve as excellent entry points for experimenting with the system mechanics.
Resource scarcity necessitates strategic planning – average acquisition rates suggest most players will obtain 3-5 Dust monthly through combined sources. This limited availability underscores the importance of selective artifact targeting rather than widespread experimentation. Understanding acquisition patterns enables effective long-term planning for optimizing key character builds.
Maximizing Dust of Enlightenment effectiveness requires understanding artifact evaluation criteria. Ideal candidates feature correct main stats combined with 3-4 desirable substats, maximizing redistribution value. Artifacts with only 1-2 viable substats typically offer poor return on investment, as the system cannot introduce new substat types.
Common optimization errors include wasting Dust on artifacts with insufficient viable substats or using them prematurely before establishing clear build priorities. Players should complete their character talent levels and weapon enhancements before committing to artifact optimization, as these provide more consistent power increases.
Advanced players employ tiered enhancement strategies: begin with artifacts displaying 3 strong substats, using initial Dust allocations to balance distributions. As Hallowed Exegesis accumulates, transition to more ambitious projects requiring guaranteed 3-4 enhancements on priority stats. This phased approach minimizes resource waste while building toward optimal endgame configurations.
Time investment varies significantly based on artifact quality and desired outcomes. Standard reshaping typically completes within 2-3 minutes per artifact, while Advanced and Decreed Reshapes may require additional decision time. Plan for 15-30 minute sessions when working through multiple artifact optimizations to maintain strategic consistency.
Integration with broader character building systems enhances effectiveness – consult our Class Guide for synergistic stat prioritization across different playstyles. Weapon selection similarly influences optimal substat distributions, as detailed in our Weapons Unlock guide.
