Verdict

Benjamin is the launch SR Lightning Slayer melee. The kit is built around Nightmare Sprint — a buff state granted if he uses Special without taking damage for 3s. Once active, his Enhanced Special charges in with clone clones for Airborne KB, and his Tag-out launches a second clone barrage that applies Lightning Affliction. His BA converts to Lightning element after the 3rd Hit, scaling all subsequent damage into the Lightning DMG % bucket.

He shines as a burst-window damage dealer behind a Lightning DPS lead. Support Skill triggers when teammates use a Special — meaning he chips in extra Lightning damage + Affliction without on-field commitment. Drop him in any Lightning team for sustained Affliction stacking and Spirit King 4pc payoff. The 3s no-damage gate for Nightmare Sprint is the skill check — facetank players never see his real damage shape.

Pull-priority: standard pool, signature SR artifact (Hawk's Flight) is the second-best SR Lightning Slayer option in the game. Skip if you already own Penny + Reina; he becomes the third Lightning slot. Pull if you have Penny only and want a melee burst partner for mono-Lightning play.

  • Story / AdventureBSingle-target clone barrage clears bosses; trash waves take longer because the kit lacks AoE outside Special.
  • Conquest / BossesANightmare Sprint Enhanced Special + Tag-out chains for big burst windows. Counter-bait into Special is the highest-skill expression.
  • Stagger / BurstBLightning Affliction on Tag-out + Ult helps Spirit King 4pc + the Lightning team payoffs. Not a stagger main.
  • Endgame / RiftsABehind Penny he provides a second Lightning burst line. Strong second-Lightning pull for mono-Lightning Conquest.
  • F2P-friendlyAStandard banner pull. Hawk's Flight SR Lightning artifact craftable, Spirit King SSR set gated but Ice Heart SR 2pc bridges.

Strengths

  • Hawk's Flight signature artifact is themed to his Nightmare passive — using Special grants Nightmare stacks (+Lightning DMG per stack, max 3 stacks +9%, +Pulse for +10% Special DMG at 3 stacks).
  • Enhanced Special after Nightmare Sprint adds clone charges + Airborne KB — high-damage single combo that converts the 3s no-damage commitment into burst.
  • BA element conversion to Lightning after 3rd Hit — all subsequent damage scales off Lightning DMG % substats, making gear stacking simple.
  • Tag-out via Nightmare Sprint deals Lightning DMG + applies Lightning Affliction — chain Tag-out + Special for sustained Affliction across the boss field.
  • Support Skill triggers on teammate Special — passive contribution to any Lightning team without on-field time.
  • C2 (Unstoppable Waves) gives Nightmare Sprint immediately on Special — bypasses the 3s no-damage requirement, the biggest QoL Canto in the game.

Weaknesses

  • Nightmare Sprint requires 3s of no damage on Special — taking ANY hit during the window forfeits the buff. Facetank players never see Benjamin's real damage curve.
  • Melee in a kit that demands clean positioning + dodge timing. Average HP / DEF curve makes him fragile against unpredictable boss telegraphs.
  • BA element conversion takes 3 hits to kick in — opening damage feels Physical / inconsistent until the combo lands.
  • Outshone by Penny + Reina for pure Lightning DPS once you own them. Benjamin is the third Lightning slot, not the lead.
  • Hawk's Flight Pulse + Nightmare stacks demand active Special usage — Cooldown management matters more than other SR Slayers.
  • Two-element rotation (Physical opener + Lightning after 3rd BA) confuses gear optimisation — stack Lightning DMG and accept the Physical opener.
The short version

Best gear

Benjamin's recommended artifact + equipment set, with farmable alternates for F2P.

Signature artifactBISHawk's FlightSR Slayer signature. Using Special grants Nightmare stacks (+3% Lightning DMG each, max 3 = +9%). Reaching 3 stacks during the duration grants Pulse: next Special DMG +10%. Themed exactly to his Nightmare Sprint identity — Special-cycle artifact for a Special-cycle kit. Craftable, SR, no banner gate.
Equipment setBIS (SSR)Spirit King (4-piece)SSR Lightning set. 2pc +8% Lightning DMG on BA for 3s — fires on every Lightning-converted BA combo. 4pc +10% Lightning DMG on attacking a Lightning-Afflicted enemy — Benjamin self-applies Affliction via Tag-out + Ult. Drops from SSR shard pool; bridge with Ice Heart 2pc + a generic 2pc until you can craft.

Alternates

  • Ice Heart (2pc) + Sticky Gorger (2pc) — SR bridge — Ice Heart 2pc gives +3% Lightning Attack Neutralization DMG, Sticky Gorger 2pc gives +3% ATK. F2P-accessible until you have Spirit King craft.
  • Shadow Lotus — SR Slayer alternate artifact — Support Skill grants Assault (+5% Lightning DMG + 3% Crit Rate, removed 1s after switch-in). Niche pick if you trigger Support frequently; Hawk's Flight outperforms in standard Special rotations.
  • Sinister Darkness — SR Slayer alternate — Special grants +5% BA DMG (10s), BA crit grants +X% Ult DMG. Generic option without Lightning gate — pick if you stick him in off-Lightning comps.
How the kit works

Kit overview

Five abilities. Nightmare Sprint is the buff; Enhanced Special / Tag-out are the payoff.

  1. SpecialNightmare Mark10s CD · Gauge 300

    Clones swing swords + Benjamin summons his blade for Lightning DMG + Airborne KB. With Nightmare Sprint active, the Enhanced Special charges + clones for additional Lightning DMG + Airborne KB. The kit's primary damage instance.

  2. Basic AttackSardonic SwordplayGauge 90

    Dual-blade combo. Hits 1-2 deal Physical DMG; from the 3rd Hit onwards, attacks convert to Lightning for the rest of the combo duration. Commit to long strings for max Lightning DMG conversion.

  3. PassiveSleepless Torrent

    If Benjamin does not take damage for 3s when using Special, he gains Nightmare Sprint. Active management — kite, dodge, then Special. C2 bypasses this requirement entirely.

  4. Tag-InRaging FlurryGauge 800

    Tag-in: dash + flurry of Lightning slashes. Tag-out (with Nightmare Sprint active): clones charge + Airborne + Lightning Affliction on hit enemies. Support Skill: teammate Special triggers Benjamin to dive in for Lightning DMG + Affliction.

  5. UltimateDimensional Annihilation Slash3 charges

    Wide dimensional slash — Lightning DMG + Airborne + Lightning Affliction. Use on grouped trash or to open burst windows. 3 charges; spend liberally.

Dupes / Canto

Canto priority

C2 is the QoL unlock. C1 + C4 are the ceiling extenders.

Canto value (in order)

  • C2 — Unstoppable Waves — Nightmare Sprint granted IMMEDIATELY on Special (bypasses the 3s no-damage requirement) + Enhanced Special CD -50% + range increases. THE Canto. Turns Benjamin from skill-gated to consistent. Top priority.
  • C1 — From Silence, Enlightenment — Enhanced Special / Tag-out during Nightmare Sprint do not consume the buff. Extends his burst window significantly. Pull-priority next jump.
  • C4 — Skills Showcase — Tag-out + Support Skill enhanced (+5000s Lightning Affliction duration, -6s Support CD) + Nightmare Sprint Strike Count +3. End-of-curve ceiling — major Affliction sustain.
  • C6 — Tea Break — Nightmare Sprint duration +5000s + Tag-out / Support DMG +20% + Enhanced Support deals additional Lightning DMG. Niche burst tool — only chase with free dupes.
  • C3 / C5 — flat statsticks — +2 skill levels + minor Tag-out / Special DMG bumps. Pickup between meaningful jumps.
On-field play

How to play him — burst rotation

Five steps. Nightmare Sprint timing is the skill check; clone payoff is the reward.

  • 1. Tag-In for combat entry — Dash + flurry of Lightning slashes. Use to enter combat at melee range without the dash hit.
  • 2. BA combo to land 3+ hits (Lightning conversion) — First 2 hits Physical; from 3rd Hit attacks convert to Lightning. Always commit to the full string. Generates Ult gauge fast.
  • 3. Bait + dodge for the 3s Nightmare Sprint window — Without C2, position to bait the boss telegraph, dodge clean, THEN Special. With C2, Special grants Nightmare Sprint immediately — skip this step.
  • 4. Enhanced Special (Nightmare Mark) for the clone barrage — Charges in + clone barrage + Airborne KB. Highest-damage single instance in his kit. Use during Nightmare Sprint for max value.
  • 5. Tag-out (Raging Flurry) for Lightning Affliction + clone clear — Tag-out during Nightmare Sprint = clones charge + Lightning Affliction. Chains with the next DPS's Special — Spirit King 4pc payoff fires the moment they hit the Afflicted enemy.
Investment by profile

Should you pull / invest?

Decide based on your existing Lightning team.

Beginner / new player

Skip unless you have no Lightning DPS at all. Benjamin's skill floor (Nightmare Sprint 3s gate) is higher than other SR Slayers. Beginners get more from Penny (passive Coin economy) or Yeonhwa (simpler crit loop). If you do pull, prioritise C2 ASAP.

F2P / low spend

Decent pull target if you want a Lightning melee burst. Hawk's Flight craftable, Ice Heart 2pc bridges Spirit King at ~75% efficiency. Build with ATK % main + Lightning DMG substats. Push C2 via standard pool — it transforms the kit.

Invested / dolphin

C2 first (Unstoppable Waves — Nightmare Sprint on Special instantly). C1 second (Enhanced Special / Tag-out preserve the buff). C4 for Affliction sustain ceiling. Skip C3 / C5 / C6 unless free dupes.

Endgame / theory-crafter

Run Penny + Benjamin + Bonnie for the launch SR/SSR Lightning core: Penny leads with Coin-economy burst, Benjamin chips in via Nightmare Sprint Tag-out + Support auto-procs, Bonnie covers Wind support (cross-element teams work — Benjamin's Lightning Affliction stacks regardless). Or Reina + Benjamin + Yeonhwa for triple-Lightning mono-element.

Quick answers

FAQ

Is Benjamin worth pulling at launch?
Yes if you do not own Penny, OR if you have Penny and want a melee Lightning burst partner. Skip if you already own Penny + Reina + Yeonhwa; he is the fourth Lightning slot in that case.
What is Benjamin's best artifact?
Hawk's Flight (SR Slayer signature). Special grants Nightmare stacks (+3% Lightning DMG each, max 3 = +9%), 3 stacks grants Pulse: next Special +10% DMG. Themed to his Nightmare passive.
What is Benjamin's best equipment set?
Spirit King 4-piece (SSR Lightning). 2pc +8% Lightning DMG on BA, 4pc +10% Lightning DMG vs Lightning-Afflicted. Drops from SSR shard pool — bridge with Ice Heart 2pc until craftable.
How does Nightmare Sprint work?
After using Special, if Benjamin takes no damage for 3 seconds, he gains Nightmare Sprint. With Nightmare Sprint active, his Enhanced Special and Tag-out fire enhanced clone barrages dealing Lightning DMG + Airborne + Lightning Affliction. C2 (Unstoppable Waves) bypasses the 3s requirement entirely.
Which Canto should I prioritise for Benjamin?
C2 (Unstoppable Waves) first — grants Nightmare Sprint instantly on Special (no 3s wait). Transformative QoL. C1 (From Silence, Enlightenment) second — Enhanced Special / Tag-out preserve the Nightmare Sprint buff. C4 for Affliction sustain ceiling. Skip C3 / C5 / C6 unless free dupes.
How do I play Benjamin in a boss fight?
Tag-in for entry. BA combo to land 3+ hits (Lightning conversion kicks in at hit 3). Bait the boss telegraph, dodge clean, Special — Nightmare Sprint procs. Enhanced Special (clone barrage) for big damage. Tag-out for Lightning Affliction + clone burst. Chain with the next DPS's Special for Spirit King 4pc payoff.
Should I stack ATK or Crit on Benjamin?
ATK % main + Lightning DMG substats + Crit DMG. Hawk's Flight scales off Lightning DMG; Enhanced Special clones deal high single-instance damage that benefits massively from Crit DMG. Crit Rate is secondary.
Benjamin vs. Yeonhwa for second Lightning Slayer?
Yeonhwa = simpler crit loop (Wraith passive + Shadow clones), better F2P-friendly. Benjamin = harder skill floor + higher ceiling once C2 unlocked (Nightmare Sprint chain). Pick Yeonhwa for casual play, Benjamin for invested Lightning teams.
Can I play Benjamin F2P?
Yes. Hawk's Flight signature artifact is craftable. Spirit King is SSR-gated but Ice Heart 2pc bridges at ~75% efficiency. C2 is the make-or-break Canto — pull standard banner for it. Solid F2P pick if you commit to active dodge play.
Does Benjamin need Nightmare Sprint to deal damage?
No, but his real damage shape requires it. Without Nightmare Sprint, Special hits at ~60% efficiency and Tag-out skips the clone barrage. With Nightmare Sprint (or C2 bypass), his burst combo doubles in output.
