Lightning Empress
Raiden Mei
Lightning Empress is Raiden Mei's original S-rank PSY-type katana battlesuit, a melee Lightning DPS who makes enemies conductive (+70% Lightning DMG taken) and gives the whole team bonus SP on entry with her leader skill. HoYoverse's old guide called her a Memorial Arena staple, but she has no Astral Ring and has long been superseded by Herrscher of Thunder, Herrscher of Origin and Lunar Vow: Crimson Love, so she is obsolete in 9.0. Her lasting use is as an Elysian Realm Support Valkyrie (+50 SP on call).

Superseded: if you own Herrscher of Thunder, Herrscher of Origin or Lunar Vow: Crimson Love, invest in them instead. Lightning Empress and Herrscher of Thunder are both in the Dorm Supply pool.

HoYoverse's guide built this for elemental teams against a single boss; it is only relevant in older content today.
Recommended teams
HoYoverse guide line-up
The line-up from HoYoverse's official guide: Lightning Empress leads for the SP bonus and conductive debuff, with Divine Prayer and Shadow Knight. A Part 1 team for older content only.
All-PSY Lightning trio
Three PSY-type battlesuits unlock the second half of her leader skill (+20% Total DMG, +26% at SS) on top of the +50 SP on entry; Valkyrie Pledge adds Lightning DMG. A budget option for Part 1 content, not for current endgame.
How to play
Core kit
- Basic ATK (Gotamashiki): a 5-hit Physical combo. With Soul Razor, hits have a 40% chance to make enemies conductive for 6s (they take 70% more Lightning DMG), and the 5th hit always makes the first non-conductive enemy conductive. Thunder Edge adds Lightning DMG to every hit.
- Special ATK (Gigavolt Spin): tap [ATK] once, then hold [ATK] for a spinning Lightning slash (Fulminating Zone). After an Ultimate Evasion, tap [ATK] to cast it directly, and it can chain one more time (twice from SS rank).
- Ultimate (Dragon May Cry): 125 SP, a huge area slash (900% ATK Physical + 900% ATK Lightning). Its last strike adds Lightning DMG per Combo Hit Count (up to 100 hits), so fire it at a high combo.
- Evasion (Lightning Speed): Ultimate Evasion gives Ignore Interrupt, less DMG taken and a Lightning field (Thunderclap), and inflicts Paralyze Trauma.
Key mechanics
- Dragon's Aura: +100% Total DMG multiplier against frozen or slowed enemies. That is why HoYoverse's guide pairs her with the Monet set (its B piece slows) and why a slowing weapon such as Pulse Katana Type-17 works on her.
- Switch entry casts Falling Thunder; her QTE Sakura Vortex triggers when an enemy is knocked airborne.
- Leader skill (Haunted Night): every battlesuit (except Herrscher of Thunder) enters with +50 SP (+70 at SS), and a team of 3 PSY-type battlesuits deals 20% more Total DMG (26% at SS).
Rotation (old content)
- Open with the weapon active (with MAG-Typhoon, tap [ATK] right after it to go straight into Gigavolt Spin).
- Basic ATK to build conductive and combo, Gigavolt Spin on grouped enemies, Ultimate Evasion whenever possible.
- Fire Dragon May Cry at a high Combo Hit Count on conductive, slowed enemies.
In the Elysian Realm, calling her as a Support Valkyrie instantly restores 50 SP to the deployed Valkyrie (CD: 40s): a handy way to cast an Ultimate early.
Strengths
- Her leader skill gives every teammate +50 SP on entry (+70 at SS), plus 20% Total DMG in all-PSY teams.
- Conductive debuff (+70% Lightning DMG taken) and +100% Total DMG against frozen or slowed enemies.
- Elysian Realm Support Valkyrie: +50 SP for the deployed Valkyrie on call.
- Standard S-rank from the Dorm Supply, and her gear is craftable in the Foundry.
Weaknesses
- Obsolete in 9.0: no Astral Ring, so she has no place in current Memorial Arena or Superstring Abyss teams.
- Superseded by Mei's later battlesuits (Herrscher of Thunder, Herrscher of Origin) and by later Lightning DPS such as Theresa's Lunar Vow: Crimson Love.
- Her damage depends on RNG conductive procs and on keeping enemies slowed.
- Her team SP bonus does not apply to Herrscher of Thunder.
Notable dupes · Rank
Leader skill upgrade (+70 SP on entry, +26% Total DMG for all-PSY teams), a third Gigavolt Spin, Thunder Cloud (20% chance to paralyze attackers) and Combo ATKs that can apply the conductive debuff.
I'm Mei: the Ultimate's last hit inflicts 5 Paralyze Trauma on all enemies and grants +40% Lightning DMG for 7s.
