How Energy Recharge Works in Genshin Impact
Energy Recharge (ER) is a core character stat that governs how quickly your Elemental Bursts become available by enhancing the Energy you gain from elemental particles and orbs. At a baseline of 100 %, ER can be boosted through artifacts, weapons, character ascensions, talents, and constellations, but it only affects energy obtained via particles and orbs, direct energy sources remain unchanged. Understanding ER’s formula, optimal thresholds for different roles, and the best ways to stack it can dramatically improve your team’s burst uptime and overall combat efficiency.
What Is Energy Recharge?
Energy Recharge is the percentage increase of Energy regenerated when absorbing elemental particles and orbs. Fundamentally, ER scales only particle- and orb-based energy gains, leaving direct energy sources (such as The Exile set’s 4-piece bonus) unaffected. The default ER value is 100 %, meaning you gain exactly the base amount of energy from each particle or orb; any value above this increases gain proportionally.
The Mechanics and Formula
Each elemental particle and orb provides a base amount of energy, particles usually grant 3 Energy, while orbs grant 9 Energy. The actual energy received is calculated as:
javaCopyEditActual Energy Gained = Base Energy × (1 + ER%)
For example, with 150 % ER, each 3-Energy particle yields 7.5 Energy (3 × 2.5). Note that ER has no effect on energy generated by normal attacks or by direct recharge sources such as certain artifact set effects and weapon passives.
Importance in Gameplay
Optimizing ER is crucial for ensuring frequent Elemental Bursts. Support characters typically aim for 200 % or more ER to reliably charge teammates’ bursts, while on-field DPS generally require 100–120 % to maintain personal uptime without sacrificing offensive stats. Off-field DPS characters often push ER even higher (circa 180–220 %) since they generate energy passively when switching back to them after particle collection.
How to Increase Energy Recharge
Artifacts
- Substats: ER appears as a possible substat on any artifact piece, with Sands of Eon offering it as a main stat.
- Sets:
- The Exile (2-piece): +20 % ER
- Scholar (2-piece): +20 % ER, plus a 4-piece that grants burst energy to bow/catalyst users on energy gain
- Emblem of Severed Fate (2-piece): +20 % ER; (4-piece) increases Elemental Burst DMG by 25 % of ER (up to 75 %)
Weapons
Several weapons feature ER as a secondary stat, making them ideal for supports and off-field DPS. Examples include the Favonius series and The Widsith, which facilitate more frequent bursts without heavy ER artifact investment
Character Progression
- Ascension Bonuses: Certain characters gain ER on ascension (e.g., Raiden Shogun, Mona, Venti at 32 % ER at level 90)
- Talents & Constellations: Select talents and constellations grant ER boosts, Keqing’s “Starward Sword” increases ER by 15 %, while some characters’ constellations passively grant ER when off-field
Other Sources
Occasionally, food buffs or event effects may grant temporary ER increases. Keep an eye on limited-time menus and effects during special events.
Optimizing Your ER Stat
Achieving the right ER balance depends on your team composition: support-focused teams lean into high ER (180 %+), while pure DPS builds often cap around 120 % to allocate artifact stats toward ATK/CRIT. Utilize in-game tools and third-party calculators to model how much ER you need for consistent burst uptime in your specific setup.
By mastering Energy Recharge mechanics, understanding its formula, knowing where it applies, and stacking it smartly, you’ll ensure your characters can unleash their powerful Elemental Bursts exactly when you need them. Keep experimenting with artifact combinations, weapons, and character-specific bonuses to find the sweet spot for your playstyle and elevate your Genshin Impact experience.
