HONKAI: STAR RAIL

Yao Guang's E2 Eidolon **Blind Arrows Guided by Feathers** grants all Zone allies +12% SPD and +16% Elation, mirroring her signature Light Cone buffs. For physical teams in Version 4.0, E2 is a significant but non-essential upgrade that primarily benefits speed-tuned compositions and multi-DPS setups.

Sparxie is a 5-star Fire Elation DPS launching in HSR 4.0 Phase 2 on February 14, 2026. She's a damage dealer with Punchline and Engagement Farming mechanics that enhance Basic Attacks and Elation damage. Optimal builds prioritize CRIT DMG and ATK through Magical Girl's Shining Medal relics and her signature Dazzled By A Flowery World light cone. Top teams pair her with Yao Guang, Sparkle, and sustain units like Huohuo.

Pure Fiction 4.0 introduces Elation Path mechanics rewarding AoE teams with massive damage amplification. Master Ultimate timing, speed tuning, and team synergy to hit 80,000 points within the four-cycle limit.

The Undying Starlight Exchange Shop forces a critical choice: spend 20 Starlight per Special Pass for guaranteed 4-star pulls within 30 attempts, or save 600 Starlight for premium Light Cones like **But the Battle Isn't Over.** This guide analyzes acquisition rates (15-100 Starlight per duplicate), exchange costs (8-600 Starlight), and ROI across F2P, low-spender, and endgame scenarios. Shop resets at 4:00 AM server time, with version 3.8 running through February 12, 2026.

Honkai Star Rail Version 4.0 introduces The Elation Path, a revolutionary gameplay system centered around Punchline stacks, Certified Banger states, and Aha Instant mechanics. Yao Guang debuts as the first 5-Star Physical Elation support character, deploying Zones that boost team Elation damage while generating Punchlines through her kit. Releasing February 12-13, 2026, this update fundamentally changes team composition strategies with new Light Cones, the Ever-Glorious Magical Girl relic set, and Planarcadia map exploration.

Sparxie's E2 eidolon (#AudienceKnows) grants one extra turn and two Thrill stacks after Aha Instant, with each Thrill stack boosting CRIT DMG by 10% for two turns (max four stacks). This fundamentally changes action economy in Elation teams through faster rotations and sustained damage amplification. E0 Sparxie remains fully playable as DPS in Elation compositions with Sparkle, Fu Xuan, and Bronya, but E2 provides measurable performance gains through extended uptime and multiplicative damage scaling.
