SP BATTERY TIER LIST: TOP 7 GENERATORS RANKED
Table of Contents
Endfield’s combat economy lives or dies on one number: how fast your team can put SP back into the shared pool. We’ve already broken down the full SP economy in our SP Economy Meta deep dive, but if you just want to know which operators actually generate the most SP per cast, this is the ranking. Seven operators currently produce meaningful SP, ranked here by raw yield, mechanical consistency, and the squad role each one fills. The data covers both SP Recovery (new points injected into the team pool) and SP Return (refunds on the operator’s own consumption), since both shape rotational throughput in different ways.
TL;DR - Key Points
- Akekuri sits at S+ alone — her Ultimate dumps 240 SP in one button (80 × 3 flares), the highest single-button yield in the game
- Arclight is the loop king — 50 SP per Skill plus a 10 SP combo refund, but only inside Electrification-enabled comps
- Pogranichnik is the engine for Physical — 35 SP per 4-stack consumption + 40 SP from his Ultimate’s Decisive Assault burst
- Endministrator self-batteries via P1 — 50% SP refund on Originium Crystal consumption, accelerating his own rotation without external help
- Tangtang is squad-wide passive — 10 SP per active Cryo Waterspout, the only sustained-AoE generation in the cast
- Frontiers 3-piece is mandatory for any battery; Thermite Cutter turns recoveries into a 28% team ATK buff at full uptime
- Intellect cap matters — Akekuri tops out at 500 Intellect for +75% Recovery; Alesh follows the same scaling rule
How the Ranking Works
Two metrics matter when you compare batteries: Recovery (raw new SP added to the team pool, which also charges Ultimate Energy) and Return (refund of points the operator just spent, which does not charge Ultimates). A 35 SP Recovery is mechanically stronger than a 50 SP Return because Recovery doubles as Ultimate fuel — but Return still keeps a self-sufficient Striker rotating without dragging the team’s Vanguard slot down.
The table below ranks each operator by Max Yield per Instance — the largest SP injection the kit produces in a single cycle, assuming the trigger condition is met. Lower-rank entries aren’t bad; they’re just narrower.
| Rank | Operator | Primary Mechanic | Max Yield | Tactical Role |
|---|---|---|---|---|
| 1 | Akekuri | Ultimate: SQUAD! ON ME! | 240 SP (80 × 3 flares) | Burst Battery |
| 2 | Arclight | Skill Loop: Tempestuous Arc | 50 SP (Skill) / 10 (Combo) | High-Velocity Loop |
| 3 | Pogranichnik | Pulverizing Front + Steel Oath | 35 SP (Skill) / 40 (Ult) | Physical Engine |
| 4 | Endministrator | P1: Final Awakening | 50 SP Return | Self-Sustain Hybrid |
| 5 | Tangtang | Whirlpool Conversion | 10 SP per Waterspout | Sustained Utility |
| 6 | Zhuang Fangyi | P3: Sense and Response | 10 SP Return | Striker Self-Battery |
| 7 | Alesh | Unconventional Lure | 5 SP Base | Niche Cryo Battery |
S+ Tier: Akekuri (Rank 1)
Akekuri occupies a category by herself. Her Ultimate, SQUAD! ON ME!, fires three flares; at max Skill Level each flare injects roughly 80 SP into the team pool, applies Link to amplify the next skill cast, and contributes to her Talent’s Stagger-trigger Recovery cycle. That’s 240 SP in a single button press — nearly an entire bar’s worth of energy delivered as one event.
The reason she sits above Arclight and Pogranichnik isn’t just raw numbers. It’s accessibility:
- She’s a 4-star. Effectively guaranteed for any account that’s pulled the standard banner consistently.
- Her trigger is Stagger. Not an elemental reaction. Heat, Cryo, Physical, Electric — every comp can use her.
- She scales with Intellect. Up to +75% Recovery bonus at 500 Intellect, with breakpoints at 100 (+15%) and 300 (+45%).
For F2P accounts targeting Authority 30+ content, building Akekuri’s Intellect first is the highest-impact rotational investment you can make.
S Tier: Arclight & Pogranichnik
Arclight (Rank 2): The Reaction-Locked Loop
Arclight’s Tempestuous Arc Skill returns 50 SP when it consumes Electrification, and her Combo Skill drops another 10 SP on a tight internal cooldown. Pure SP-per-second math, she’s actually the fastest sustained generator in the game — if your comp can keep Electrification stacks active. Outside of Electric squads (or comps using Perlica’s forced-Electrification Combo Skill), her loop falls apart and she becomes a net SP drain.
Her ceiling is the Infinite Loop archetype: pair her with a forced-reaction source and her Skill becomes a perpetual battery that fuels Akekuri-flare or Fangyi-transformation rotations on a 6-10 second cycle.
Pogranichnik (Rank 3): The Physical Recursion Engine
Pogranichnik isn’t just a battery — he’s the operator that defines Physical comp viability. His Battle Skill consumes Vulnerability stacks and recovers SP based on how many it ate:
| Stacks Consumed | SP Recovered |
|---|---|
| 2 stacks | 15 SP |
| 3 stacks | 25 SP |
| 4 stacks | 35 SP |
At Potential 5, his Newly Forged Blade capstone applies a 1.2x multiplier to those numbers (4-stack consumptions deliver ~42 SP) and trims two seconds off Combo Skill cooldown. His Ultimate, Steel Oath / Shieldguard Banner, Forward, finishes with a Decisive Assault burst worth 40 SP dropped into the pool.
The interaction that makes him dominant: every consumption cycle accelerates the next consumption cycle. Pair him with a Vulnerability accelerator like Rossi or Chen Qianyu and the rotation becomes recursive — stacks come in, stacks get consumed, the pool refills, the carry burns it, repeat.
A Tier: Endministrator (Rank 4)
Endministrator is a fundamentally different kind of generator. He doesn’t add SP to the team pool — he refunds his own. At Potential 1 (Final Awakening), consuming Originium Crystals during his Battle Skill triggers a 50% SP refund on that cast.
Why this matters: a typical 60-cost Battle Skill that returns 30 SP changes the operator’s effective consumption from 60 to 30. That’s a doubled cast frequency without any external Vanguard support. In comps where Endministrator is the carry, this self-sustain frees the Vanguard slot to be a buff carrier (Ardelia, Wulfgard) or a Vulnerability stacker (Rossi) instead of a pure battery.
He’s ranked below the team-pool generators because Return doesn’t charge the team’s Ultimates — but inside his own rotation, he’s the second most efficient SP user in the cast after Akekuri.
A Tier: Tangtang (Rank 5)
Tangtang is the only operator on this list that generates SP passively over duration. Her Cryo Waterspouts deal damage-over-time and drip 10 SP per active Waterspout back to the squad while they’re up. With multiple spouts active and her Ultimate’s time-stop window layered on top, she patches the gap on bosses where Final Strikes get interrupted and the squad’s primary regen avenue collapses.
Her role isn’t burst — it’s filling the dead time between Pogranichnik consumptions and Akekuri flares. On long fights (Umbral Monument extended chambers, Contingency Contract Risk 18+), her sustained drip becomes meaningful. On short Stagger-and-burst encounters, she’s outclassed by the top three.
B Tier: Zhuang Fangyi & Alesh
Zhuang Fangyi (Rank 6): The Striker That Funds Itself
Fangyi isn’t a Vanguard. She’s the first 6-star Electric Striker, and she shows up on this list because her Potential 3 (Sense and Response) returns 10 SP every time her Battle Skill consumes Electrification. Inside her Smiting Tempest Ultimate transformation, the Combo Skill cooldown drops 4x, the first Battle Skill is free, and the consumption rate becomes high enough that Return funds most of her own rotation.
She’s ranked sixth because 10 SP Return is small compared to the top-tier numbers — but the team-building implication is huge. With Fangyi self-funding her Skill costs, the comp’s actual Vanguard stops being chained to battery duty.
Alesh (Rank 7): The Niche Cryo Specialist
Alesh’s Unconventional Lure delivers a base 5 SP on Cryo consumption, scaling up at higher Potentials. He’s at the bottom of the ranking because the yield is small and the trigger is narrow — Cryo-only — but he fills a specific role in Cryo comps where you need a 4-star battery that doesn’t compete with Akekuri’s slot. Like Akekuri, his Recovery scales with Intellect, so the same gear-investment logic applies: pump Intellect via Frontiers 3-piece and Artificing, and his contribution scales linearly.
Mandatory Performance Modifiers
Raw operator yield is the floor. The ceiling is set by the gear, weapons, and consumables that multiply the Recovery loop. None of these are optional for high-tier rotational play.
The Frontiers 3-Piece Set
Frontiers is the standard-issue battery set. The 3-piece bonuses are designed precisely around the Recovery trigger:
- +15% Combo Skill CDR — fires the primary SP-generation skill more often
- +16% Team DMG for 15s on SP Recovery — folds team-wide damage into the same trigger that fills the bar
For Intellect-scaling generators (Akekuri, Alesh), the kit’s Secondary Attribute boosts also help reach the +75% Recovery cap at 500 Intellect without burning expensive substat rolls.
Thermite Cutter (6-Star Sword)
The single most-recommended weapon in the game — and a fixture on our weapon tier list. Its Flow: Thermal Release passive grants a 16% team-wide ATK buff every time the wielder recovers SP, stacking up to 28% team ATK at full uptime. Akekuri and Pogranichnik trigger SP Recovery often enough to hold the buff at 100% uptime in any real fight. See our Thermite Cutter deep dive for the full passive math.
Intellect Optimization
For Akekuri specifically, the Recovery bonus is mathematically capped by the Intellect stat:
| Intellect | SP Recovery Bonus |
|---|---|
| 100 | +15% |
| 300 | +45% |
| 500 (cap) | +75% |
Hitting 500 Intellect is the difference between “good battery” and “the rotation never stops.” It’s also achievable with a clean Frontiers 3-piece roll plus moderate Artificing — see our Attribute Scaling & Artificing breakdown for the multiplicative formula.
Consumables: The AIC Tax Most Players Skip
Perplexing Medicine (Buckflower + Citrome) grants +23.76% Ultimate Gain Efficiency. For Akekuri-flare comps and Fangyi-transformation comps, this consumable shaves seconds off time-to-burst — which on interrupt-windowed bosses is the difference between a clean run and a wipe. Treating consumables as a free additional gear slot is the correct framing for Authority 30+ encounters.
Practical Takeaways
If you’re building a battery slot from scratch, the priority order is unambiguous:
- Build Akekuri first. She’s a 4-star, the trigger is universal, and her ceiling is the highest in the game.
- Add Pogranichnik for Physical comps. His recursion makes Steel Oath / Vulnerability archetypes work.
- Slot Arclight only inside Electric comps with a forced-reaction partner. Outside that context, she underperforms.
- Treat Endministrator’s refund as Striker tech, not battery tech. He frees the Vanguard slot for buffs.
- Tangtang and Alesh are situational. Build them after the top three are gear-complete.
- Frontiers 3-piece + Thermite Cutter is non-negotiable for whichever battery you’re running.
The pattern across every Authority 30+ clear is the same: the team that wins isn’t the one with the highest damage stat. It’s the one whose battery, gear set, weapon, and consumable all fire on the same beat. Pick the operator that fits your comp, lock in the modifiers, and the SP economy stops being a constraint.
