Who is Reverse: 1999 Corvus & What Makes Her Stand Out?
Corvus is a 6 star Intellect Arcanist introduced in The Midnight Whistle update. Her kit is built around Dynamo mechanics, heavy stat stacking, and strong team buffs. When given time to set up, she becomes one of the most reliable boss killers that you can grab from the entire roster.
Corvus focuses on deleting single targets rather than clearing waves. Her damage ramps up through debuffs and stacking effects, which means longer fights actually favor her playstyle.
Welding reduces enemy Mental Defense, opening the door for higher team damage. At the same time, Electric Arc stacks of Corvus push her attack scaling to very high levels, especially with portraits unlocked. Pulsing Field ties everything together by boosting Ultimate and Incantation damage for the entire team, not just herself.
This combination makes her extremely effective when the goal is melting bosses instead of rushing short fights.
Corvus Kit Overview
Corvus focuses on building Dynamo stacks, reaching up to 30, which then feed into Pulsing Field to provide strong buffs for the whole team. At the same time, she stacks Electric Arc or Flickering Arc on herself, increasing her personal attack by 0.3% for each stack.
Her Breaking Point debuff adds extra effects when she channels her main skill, Sew It All Up, making her damage even more potent. This combination of personal scaling and team-wide buffs allows Corvus to deal consistent single-target damage while supporting the rest of the team.
Core Skills (Max Rank)
| Skill | Type | Key Effects |
| Arc-Threaded Shot | 1-Target Mental DMG | 500% DMG + 8 [Electric Arc] stacks + 1 [Breaking Point]. Fast stack builder. |
| Rosy Cracks | Channel [Stitching] (2 rounds) | Applies [Welding]: Enemy Mental DEF -1% per Mental hit (up to -50%), grants Corvus extra [Electric Arc] on attacks. Prioritizes [Sew It All Up] target. |
| Sewn into Forever (Ultimate) | 1-Target Mental DMG | 700% DMG + 1 [Breaking Point] + [Sew It All Up] (400% base, transfers 20 [Dynamo] to [Pulsing Field]; scales to +600% at Lv.3 with 5% DMG per Arc stack). No draw cost (Insight I). |
Insights Priority
Unlock in this order for core mechanics first with Corvus:
| Insight | Priority | Effects |
| I: Full Steam Ahead | ★★★★★ (Must) | Battle start: [Amplified Surge] (Moxie +3/+5 at Lv.3, Control immune). +10 [Dynamo] per action. Auto [Pulsing Field Lv.1] if none. Ult free draw. Lv.3 end: 2 Arc → 1 Dynamo + 2 [Flickering Arc]. |
| II: Full Steam Ahead | ★★★★☆ | +10% Crit Rate on entry. |
| III: Full Steam Ahead | ★★★☆☆ | [Welding] transfers to lowest HP enemy (boss priority) on death. |
Corvus Insight Stats and Portrait Priority
At level 60, Corvus has the following base stats: Attack 1163, HP 6336, Technique 456, Critical Rate 15.2%, Critical Damage 22.8%. These numbers set the foundation for her scaling in combat and determine how quickly she ramps up damage through her stack mechanics.
Portrait Priorities and Effects
We recommend you to focus on portraits in this order: 1, 2, 3, 4, 5. Each portrait improves Corvus kit in a specific way:
- Portraits 1 and 2: Double the duration and stacking speed of Sew It All Up, giving more uptime for damage and team buffs.
- Portraits 3 and 4: Boost per-stack damage, making each Electric Arc or Flickering Arc hit harder.
- Portrait 5: Doubles Arc gains and raises maximum stack caps, letting Corvus reach her full potential faster and maintain higher attack scaling throughout fights.
Optimizing these portraits ensures Corvus hits her peak damage while keeping Pulsing Field buffs active for the team.
Best Corvus Builds
So, what makes a perfect Reverse: 1999 Corvus build? It comes through the best Psychubes and teams. So, this is what we recommend you to go with her:
Psychubes (R10+ Recommended)
Focus on ultimate Might/Crit Rate/ATK% for [Sew It All Up] nukes. Permanent [Stitching] uptime favors channel-synergistic options.
| Psychube | Priority | Why It Works |
| On the Hand of Time | ★★★★★ | 14-28% Penetration (stacks via channel). 18-36% Crit DMG after 2 Ults. BiS for all content. |
| Bitter March of the Living | ★★★★☆ | Sig: 16% Crit Rate, 12-24% Ult Might, 8.4-18% DMG. Strong if Hands of Time on supports. |
| Stray Off the Path | ★★★★☆ | 16% Crit Rate, 12-24% Incant Might (for [Sew]), 18-36% Crit DMG. Extra action synergy. |
| Balance, Please | ★★★☆☆ | 18% Ult Might + 12-24% DMG Bonus. Weaker vs Spirits. |
| Never-Ending Q&A | ★★★☆☆ | Up to 12-24% Ult Might (4 Ults) +10% ATK. Long fights only. |
Corvus Team Building
Corvus thrives in Dynamo FUA teams as Lucy sub. Pair with [Dynamo] enablers for [Pulsing Field] ramp-up.
| Team | Roles | Notes/Alts |
| Laplace Asylum (Dynamo FUA) | Corvus (Carry), Charon (Buffer/Sub-DPS), Ulrich (Buffer), Medicine Pocket(E) (Sustain) | Core meta. Corvus swaps Lucy for ST. Alts: Melania(E)/Mercuria sustain. |
| Dynamo Burst | Corvus, Brume (Sub-DPS), Ulrich, APPLe (Sustain) | Hands of Time on Brume if shared. High Ult spam. |
Rotation:
- S2 [Rosy Cracks] → [Welding] on boss.
- S1 spam for Arc stacks/Dynamo.
- Ult when [Pulsing Field Lv.3] ready → massive [Sew It All Up].
- Maintain [Stitching]; reapply S2 as needed. Supports Ult/FUA for burst windows.
Corvus Strengths and Weaknesses
Before you decide if it is worth to pull Reverse: 1999 Corvus or not, it is a must to learn both her strengths and weaknesses. So, these are what comes with her:
- Strengths: Corvus excels at single-target damage, with scaling that grows extremely high the longer she stays in combat. Her team buffs from Pulsing Field amplify the overall damage output, while her Breaking Point debuffs shred enemy Mental Defense, making her a powerful asset against bosses.
- Weaknesses: She requires 2 to 3 turns to fully set up, which can leave her less effective in short fights. Her area-of-effect damage is limited, so she struggles against groups of enemies. Additionally, her channeled abilities make her vulnerable to interruptions, so timing and protection are important for maximum effectiveness.
Is Corvus Worth Pulling?
Corvus sits comfortably in S tier, and performs best in single target burst situations where setup time is not a drawback. She works as a strong alternative to Lucy in Dynamo teams, offering a slightly different approach with heavier debuff pressure and team wide buffs.
Electric Arc stacking allows her attack to scale aggressively, reaching very high values with portraits. Welding ensures enemies take more Mental damage, while Pulsing Field adds large bonuses to Ultimate Might, Incantation Might, and overall damage output.
For players focusing on endgame content like Mane’s Bulletin or Limbo, Corvus brings long term value and fits well into future team planning. Those searching for a dependable Intellect carry for boss focused modes will find her to be a solid investment.
Pull Value Breakdown
| Scenario | Recommendation | Reason |
| F2P/New Players | Skip if you have Lucy | Lucy provides better AoE and easier FUA uptime in Laplace Asylum teams. Save for upcoming healers or multi-attribute carries. |
| Boss-Focused (Limbo, World Bosses) | High Priority (Pull) | Her ultimate [Sewn into Forever] + [Sew It All Up] nukes with 700-1200% base Mental DMG, scaling to thousands% effective with stacks and portraits. Ideal for ST phases. |
| Whale/Collection | Must-Pull | Future-proofs Dynamo comps; portraits push her to god-tier burst. |
| Lucy Owner | Medium Priority | Use as ST swap-in; her setup (2-3 turns for max [Pulsing Field Lv.3]) trades AoE flexibility. |
Pull if you’re struggling with single-target content or lack Lucy alternatives. She’s not “meta-defining” like Charon but elevates Dynamo teams to S+ clears. If summons are tight,Enjoygm offers secure top-ups tied directly to her event banner pulls, ensuring you hit pity without hassle.
Conclusion
So, that is all we have for the Reverse: 1999 Corvus guide. Using these guidance, decide if she is worthy for your team so you can confidently pull her to your team right now.
