HSR Sparxie E0S1 Guide: 340 Pulls & Oneiric Shard Math

Understanding E0S1: What You're Pulling For

E0S1 delivers the most cost-efficient power spike for limited 5-stars. E0 = base character without Eidolon duplicates. S1 = one signature Light Cone copy. This combo provides 70-80% of max potential at a fraction of higher Eidolon costs.

Sparxie, the 5-star Fire Elation character in Version 4.0 Phase 2, pairs with Dazzled By A Flowery World Light Cone. This weapon grants CRIT DMG +36% and increases Skill Point upper limit by +1 per Elation character (max +3). Signature Light Cones typically provide 25-35% damage increases over best 4-star alternatives.

Players seeking competitive value can buy Oneiric Shards online through buffget's secure platform for efficient top-ups with fast delivery.

Why E0S1 Is Optimal

E0S1 efficiency stems from diminishing returns on Eidolons. E1/E2 cost 180 pulls each (worst-case) for 10-20% performance gains. Signature Light Cones need only 160 pulls max and deliver 25-35% damage improvements. For mid-to-high spenders, E0S1 across multiple characters builds roster depth better than E2+ on single units.

HSR 4.0 Phase 2 Banner Details

Sparxie Character Event Warp launches March 6, 2026 (10:00 PM UTC-5 NA / 11:00 AM UTC+8 Asia), running through March 26 (20 days).

Phase 2 features simultaneous Light Cone Event Warp with Dazzled By A Flowery World. Both banners use separate pity counters—Character progress doesn't affect Light Cone pity. Budget independently for each.

Character/Light Cone Event Warps consume Star Rail Special Passes or 160 Stellar Jade per pull. Pity carries over between same-type banners (Yao Guang progress transfers to Sparxie), but Light Cone pity stays completely separate.

Complete Pity System Breakdown

Character Event Warp:

• Hard pity: 90 pulls
• Soft pity: Starts pull 74
• Base 5-star rate: 0.6%
• Most 5-stars arrive: Pulls 75-85

Light Cone Event Warp:

• Hard pity: 80 pulls
• Soft pity: Starts pull 63-75
• Base 5-star rate: 0.8%
• Average acquisition: 70-75 pulls

50/50 System and Guarantees

Character Event Warp: 50% chance for featured character vs. 50% standard banner 5-star. Losing activates guarantee—next 5-star is 100% featured. Guarantee persists across banner rotations.

Light Cone Event Warp: 65% featured rate on first 5-star pull. Worst-case requires 160 total pulls (two consecutive off-banner 5-stars).

Pity Carryover

Pity transfers seamlessly between same-type banners. 60 pity on Yao Guang's banner = 60 pity toward Sparxie (30 from hard pity). Lost 50/50s remain active until claimed.

Pity never transfers between different banner types. Character, Light Cone, and Standard Warp pity stay separate.

Oneiric Shard Conversion Guide

Oneiric Shards convert 1:1 to Stellar Jade. Each pull = 160 Jade = 160 Shards.

Primary Bundles (First-Time Bonus Doubles Initial Purchase):

• $0.99: 60 Shards (120 first-time)
• $4.99: 300 Shards (600 first-time)
• $14.99: 980 Shards (1,960 first-time)
• $29.99: 1,980 Shards (3,960 first-time)
• $49.99: 3,280 Shards (6,560 first-time)
• $99.99: 6,480 Shards (12,960 first-time)

After first-time bonuses, repeat purchases give base amounts plus small bonuses (+30 on $4.99, +110 on $14.99).

Bundle Optimization

All first-time bonuses = 26,160 Shards for $294.94 (163 pulls). Covers nearly half worst-case E0S1.

$99.99 bundle: Best value at ~$0.77/pull with first-time bonus vs. $0.83/pull on $0.99 bundle. For 50+ pulls, prioritize higher-tier bundles.

Worst-Case: Maximum Shards Needed

Character Event Warp: 180 pulls max (lose 50/50 at 90 pity + 90 for guarantee) = 28,800 Jade

Light Cone Event Warp: 160 pulls max (two off-banner 5-stars at 80 pity each) = 25,600 Jade

Total Worst-Case: 340 pulls = 54,400 Stellar Jade = 54,400 Oneiric Shards

To acquire 54,400 Shards optimally with first-time bonuses: ~$500-550 depending on bundle combinations.

Average-Case: Realistic Expectations

Soft pity reduces average costs significantly. Most 5-stars arrive pulls 75-85 on Character Event Warp (avg 82-85). With 50/50, expect 140-150 total pulls for featured character.

Light Cone soft pity concentrates pulls 65-75 (avg 70-75). 65% featured rate means ~35% need two 5-star pulls. Average: 95-105 pulls for signature.

Combined Average:

• Character: 140 pulls = 22,400 Jade
• Light Cone: 95 pulls = 15,200 Jade
• Total: 235 pulls = 37,600 Jade = 37,600 Shards

37,600 Shards requires ~$300-350 with first-time bonuses.

For efficient top-ups, Honkai Star Rail top up fast through buffget's platform with competitive pricing and secure transactions.

Why Average-Case Works

70-75% of players secure E0S1 within 235 pulls or fewer. Remaining 25-30% typically fall within 250-280 pulls, not full 340 max. Budgeting 250-260 pulls (40,000-41,600 Shards) provides strong security without excessive over-preparation.

Best-Case Scenario

Theoretical minimum: 2 pulls (1 character, 1 Light Cone) at ~0.006% odds.

Realistic best-case: Pull Sparxie at 75 pity (win 50/50) + signature at 65 pity (win 65%) = 140 pulls = 22,400 Jade.

Don't budget for best-case. With only 20 days available, running out mid-banner forces rushed, inefficient top-ups. Budget worst-case or average-case; treat early pulls as bonuses for future banners.

Optimizing Your Top-Up Strategy

First-Time Bonuses: Most impactful optimization. Never reset—prioritize before repeat purchases.

Express Supply Pass: $4.99 = 300 Shards immediately + 90 Jade daily × 30 days (2,700 total) = 3,000 Jade (18.75 pulls) at $0.27/pull. Best value available. Stacks up to 179 days; excess refunds 330 Shards.

Free Stellar Jade During Banner

Version 4.0 Phase 2 (20-day banner):

• Daily Training: 60 Jade daily = 1,200 total
• Simulated Universe weekly: 225 Jade = 675 (three weeks)
• Version events: ~1,600-2,000 Jade
• Maintenance compensation: 300 Jade
• Conservative estimate: 3,500-4,500 free Jade (21-28 pulls)

With Express Supply Pass: +1,800 Jade (11 pulls) = 32-39 free pulls total. Subtract from target pull count to reduce required top-ups.

Monthly Pass + Battle Pass

Nameless Honor (Battle Pass): 680 Jade free track + 1,320 Jade + 4 passes premium ($9.99) = 16.25 pulls.

Combined with Express Supply Pass: ~37 pulls for $14.98. Players maintaining both throughout Version 4.0 enter Phase 2 with 30-40 accumulated pulls, reducing E0S1 requirements from 54,400 to 32,000 Shards worst-case.

Step-by-Step: Your Personal Budget

Step 1: Inventory Resources Sum Stellar Jade + Star Rail Special Passes (1 pass = 160 Jade) + Oneiric Shards. Example: 5,000 Jade + 20 passes = 8,200 Jade (51 pulls)

Step 2: Check Pity Counters Access Warp Records. Count pulls since last 5-star on Character and Light Cone banners separately. Example: 35 pulls since last 5-star = 35 pity (55 from hard pity)

Step 3: Verify Guarantee Status Last Character Event Warp 5-star featured or off-banner? Off-banner = guarantee active.

Step 4: Calculate Remaining Pulls Worst-case with 50/50 and 0 pity: 180 character + 160 Light Cone = 340 total. Subtract current pity on each banner + saved pulls. Example: 35 character pity + 51 saved = need (180-35) + 160 - 51 = 254 pulls

Step 5: Convert to Shards 254 pulls × 160 = 40,640 Shards needed

Step 6: Select Bundles Prioritize first-time bonuses. 40,640 Shards: $99.99 (12,960) + two $49.99 (13,120) + $29.99 (3,960) + two $14.99 (3,920) + two $4.99 (1,200) = 35,160. Add one $49.99 (6,560) = 41,720 total.

Common Mistakes to Avoid

Mistake 1: Forgetting Light Cone pity is separate. Budgeting 180 pulls for E0S1 ignores the 160-pull Light Cone requirement. Always calculate both independently.

Mistake 2: Assuming soft pity guarantees 5-star. Some players hit full 90-pull hard pity. Budget for hard pity; treat soft pity as bonus.

Mistake 3: Not tracking guarantee status. Guarantee needs only 90 max pulls vs. 180 for 50/50—a 14,400 Jade ($100+) difference.

Mistake 4: Ignoring free event Jade. Version events provide 1,600-2,000 Jade. Failing to account wastes $15-20 in unnecessary purchases.

Alternative: When to Skip Signature

Budget constraints may justify E0S0. Sparxie functions with 4-star alternatives, sacrificing 20-30% damage while saving 15,200-25,600 Jade (95-160 pulls).

Best 4-Star Alternatives:

• Swordplay: CRIT Rate buffs + damage bonuses (strongest F2P)
• Carve the Moon, Weave the Clouds: CRIT DMG + ATK% scaling

Both reach 70-75% of signature performance at S5. Casual players clearing standard content don't need signature. Competitive players targeting Memory of Chaos 12-star or Pure Fiction high scores benefit substantially from S1.

E1 vs S1 Investment

After E0, choose E1 (first Eidolon) or S1 (signature Light Cone). For Sparxie, S1 typically provides greater damage than E1.

E1 worst-case: 180 pulls (28,800 Jade) S1 worst-case: 160 pulls (25,600 Jade)

Signature Light Cones deliver 25-35% damage increases. E1 effects vary—some give 15-20% improvements, others offer quality-of-life with minimal damage impact. Research Sparxie's specific E1 before committing.

FAQ

How many Oneiric Shards for guaranteed E0S1 Sparxie? Worst-case: 54,400 Shards (340 pulls)—180 for character after losing 50/50 + 160 for signature. Average: 37,600 Shards (235 pulls) with soft pity.

What happens to pity after getting Sparxie? Character Event Warp pity resets to 0 after any 5-star. Next 5-star faces 50/50 again. Light Cone pity operates independently—pulling Sparxie doesn't affect it.

Pull character or Light Cone banner first? Prioritize Character Event Warp. Signature provides minimal value without the character. Sparxie functions with 4-star alternatives. Secure character first; delay Light Cone if budget exhausted.

Do first-time bonuses reset in Version 4.0? No. First-time bonuses never reset. Once claimed, they're permanent across all versions. Subsequent purchases give only base amounts plus small repeat bonuses.

How does soft pity affect pull requirements? Soft pity (pull 74 Character / 63 Light Cone) increases 5-star rates progressively. Most obtain 5-stars pulls 75-85, reducing average costs below 90-pull hard pity. Budget for hard pity to guarantee success; expect soft pity to reduce actual spending.

Can I get signature Light Cone from Standard Banner? No. Dazzled By A Flowery World appears exclusively on Light Cone Event Warp during Sparxie's banner. Standard Banner features only permanent 5-stars. Limited signatures require pulling specific rate-up banners.
