Why R5 Rust vs. Polar Star Even Matters for Tartaglia’s Kit
Tartaglia’s whole deal is built around melee Normals – they make up about 80% of his damage output, with base scalings from 38.9% to 72.8% at Talent Level 1. The rest? Charged Attacks, those Riptide Slashes (60.2% AoE Skill damage popping off every 1.5 seconds), and his Burst (378.4% in Ranged stance or 464% in Melee). Polar Star? It juices the entire kit with up to +48% ATK across all those attacks. In a 24-second Vaporize cycle, you’re looking at around 15,000 total Hydro damage (assuming 2,000 ATK, 200% CRIT DMG, and 50% CRIT Rate). Rust hits 13,200 in the same setup, but it kinda glosses over Riptide and hits Charged attacks harder with that penalty.
In a tight 9-second melee window (think mN2C plus mN3C combos), Polar Star edges out 10-15% higher personal DPS over Rust in Vaporize squads. Why does this comparison hit home? Because Tartaglia’s not just a button-masher; his stance-swapping and Riptide procs demand weapons that play nice with the full package.
Get Tartaglia to Level 90 using 168 Starconch, 46 Cleansing Heart, the usual Varunada Lazurite lineup, and 420,000 Mora. Talent priorities? Pump Skill to L9 or higher for reliable Riptide uptime, Burst to L9+ to snag that +20 energy refund from Ranged stance, and Normal to at least L6 for solid melee foundations. And hey, always double-check your builds with in-game combat logs – aim for 115-145% Energy Recharge to keep Bursts flowing without a hitch.

Breaking Down R5 Rust: Stats, Passive, and How It Plays
R5 Rust, that trusty 4-star Bow, clocks in at 510 Base ATK at Level 90 with a 41.3% ATK% substat. It scales beautifully into melee Normals, letting you spam without burning stamina like crazy. The passive? A whopping +80% to Normal damage, offset by -10% on Charged Attacks – which bites into those mN2C combos (two Normals into a Charged). In pure single-target, no-Charged scenarios, it supercharges a full 5-Normal string by +80%, pushing you past 2,000 ATK easy. But it straight-up ignores Riptide Slashes (that 60.2% Skill damage) and dings Charged cross-slashes (60.2% plus 72% Hydro), dragging efficiency down by about 20% in 9-second melee loops.
To R5 it, snag duplicate Bows and burn through ~500,000 Mora on enhancement ores. Slot it into F2P kits that dodge Charged attacks altogether, like mN5C for stamina-neutral flow. Pair with 4pc Heart of Depth (+15% Hydro DMG from the 2pc, and +30% to Normal/Charged after Skill for 15 seconds) – farm that from the Peak of Vindagnyr domain. Substats priority: CRIT Rate/DMG in a 1:2 ratio (at least 50/200) beats out ATK%, then Energy Recharge (155%+ for Burst uptime without a battery).
Rust sits at #18 in Tartaglia rankings, A-tier for budget warriors hitting 80% of 5-star output. In mono-Hydro teams, that ATK% substat glows without reactions muddying things – though its lower base ATK (compared to Polar Star’s 608) means you’ll grind artifacts harder for comp. Oh, and if you’re crafting, Hamayumi R5 (55.1% ATK%, +32% Normal at full Energy) gives similar F2P vibes to Rust.
(Quick editor note: I’ve seen Rust carry so many early-game clears – it’s forgiving if you’re still learning Tartaglia’s stance dance.)
Polar Star Unpacked: Stats, Passive, and Real Performance
Enter Polar Star, Tartaglia’s 5-star signature Bow: 608 Base ATK at 90, plus a 33.1% CRIT Rate substat that nails the 1:2 CRIT balance (50% Rate, 200% DMG). At R5, the passive dishes +24% Skill/Burst DMG, plus up to four stacks of +12% ATK each (max +48%). You build stacks from Normal/Charged hits (up to four, lasting 12 seconds), Skill (separate four, 12s), and Burst (another independent four, 12s). In a 9-second melee burst, snag 2-3 from Normals/Chargeds and one from stance switch for full uptime. It vibes perfectly with Riptide – marks trigger stacks too – adding +24% to Slashes and Burst, for an overall +22% melee damage boost at 100% stacks. Kick off with Ranged Burst for that +20 energy refund, and you’re golden.
Polar Star owns #1 spot for sheer versatility, SS-tier in Vaporize teams. And with C1, you stretch melee to 11-14 seconds, stacking even more chaos.
Ever wonder how a weapon can feel so tailored? Polar Star just clicks with Childe’s kit – it’s like it was designed in his image.
Head-to-Head: Crunching the DPS Numbers
Based on sims for C0 Tartaglia (2,000 ATK, 50% CRIT Rate, 200% CRIT DMG, with Bennett buffs), in a 24-second Vaporize rotation (Ranged Q into 9s Melee E then Q E again): Polar Star pumps out ~15,000 Hydro DMG, while Rust trails at ~13,200 – that’s 10-15% higher personal DPS for Polar. The gap widens with C1, cutting Skill CD by 20%. For melee specifics, mN2C + mN3C (Normals at 38.9%-72.8%, Charged 60.2%+72%): Polar Star layers +48% ATK and +24% Skill on Riptide; Rust pumps +80% just on Normals, -10% on Charged, ending up ~20% lower per 6-hit combo. Burst-wise, Ranged hits 378.4% AoE with +24% from Polar Star (R5), nothing from Rust; Melee’s 464% gets amplified the same way by +120% Riptide Blast. Those Riptide procs (60.2% every 1.5s, quadratic AoE) toss in 15% more CRIT hits under Polar Star.
Apply Riptide with a Charged or C4. Run two melee cycles (9s each to beat the <20s CD). Check the combat menu for % contributions – Polar Star clears AoE packs 5-10% quicker.
Single-target? Rust sneaks a 5% edge if you skip Charged. Multi-target? Polar Star surges 12-15% ahead.
Artifacts and Stats: Making It All Synergize
Polar Star’s built-in CRIT Rate lets you slap on a CRIT DMG Circlet; Rust demands more CRIT Rate pieces to compensate. Both thrive on 4pc Nymph’s Dream (+25% ATK/+15% Hydro at max stacks), which plays nicer with Polar Star’s hit triggers than Heart of Depth’s +30% Normal/Charged (15s after Skill). Core stats: 50/200 CRIT (1:2), 2,000+ ATK, at least 120% ER. For Rust, grab ATK% Sands unless you’re Bursting Vaporize; Polar Star frees up slots for 100-200 EM subs on reactions. Goblet? Hydro DMG Bonus is non-negotiable.
Farm Nymph’s Dream or Heart of Depth domains. Balance that 1:2 CRIT with a simulator like Genshin Optimizer. Steer clear of overcapping CRIT Rate above 70%.
On a budget? Mix 2pc Hydro + 2pc ATK. With Rust, stack CRIT Rate hard; Polar Star handles it out of the box.
How Team Comps Shake Up Weapon Choices
In the classic International team (Tartaglia main DPS, Xiangling sub-DPS, Bennett support, Kazuha for grouping), Polar Star outpaces Rust by 12% thanks to stack uptime during quick swaps – Rust barely squeezes in five Normals per cycle. Tartaglia lays down Hydro in melee for Xiangling’s Pyro Vaporize (x1.5 multiplier); Kazuha’s VV shreds resistance for both; Bennett’s ATK buff scales Rust nicely. Vaporize amps Polar Star’s +24% on Riptide/Burst; Rust lags 5% behind. Switch to Electro-Charged with Fischl/Beidou? Polar Star’s CRIT Rate boosts Riptide procs. Throw in Furina, and Polar Star multiplies her Fanfare damage through stacks.
Key supports: Bennett for ATK (Rust loves it), Kazuha for VV shred (works for both), Furina for DMG% (Polar Star synergy), Xiangling for Vaporize. Start with supports (Xiangling Q). Tartaglia opens Ranged Q for stacks and energy. Dive into 9s melee for Hydro application. Swap for buffs, recast E. ER needs: 170-190% sans battery; drop 10-15% with a Favonius buddy.

Testing in the Wild: How They Fare in Spiral Abyss
From real runs, Polar Star shaves 2-3 seconds off Floor 12 waves in AoE thanks to Riptide’s quadratic scaling. Rust holds its own on single-target bosses but falters in multi-mob chaos. At C0 with 4pc Nymph’s and 9s melee (mN2CD + mN3CD), Polar Star shoulders 40-50% of team damage in Vaporize. Single-target clears? Rust works fine with stamina-capped mN5C. For AoE dominance, Polar Star’s stacks on Riptide (10s mark +8s passive =18s window) shine – dash or jump cancel after Charged to speed up strings.
Log 36-star clears, tracking times and damage. Cluster enemies for Riptide pops. Time your Vaporize on melee hits. This assumes AR45+; Rust gets you through early-game no sweat.
(My take as an editor: Nothing beats that Abyss satisfaction when stacks align perfectly – Polar Star just makes it smoother.)
Breaking Down the Investment: Cost vs. Bang for Your Buck
Polar Star demands ~180 pulls on the Weapon Banner. R5 Rust? 100-200 pulls or 500,000 Mora. Value play: Polar Star’s 20-25% DPS lift comes with 2.5x Mora efficiency; Rust hits 80% performance at a third the cost, especially if you’re gearing multiple characters like Yoimiya. Alternatives? Thundering Pulse (#2, 66.2% CRIT DMG, +40% Normal stacks) is close; Viridescent Hunt (Battle Pass 4-star, 27.6% CRIT Rate) for F2P; Hamayumi for craftable Rust energy.
Upgrade path: Low-budget (Rust + HoD) to mid (Viridescent + Nymph’s, +15-20% DPS) to high-end (Polar Star + C1). Total talent books: 4,957,500 Mora, 3 Teachings/21 Guide/38 Philosophies of Freedom, 6 Shard of Foul Legacy, 1 Crown. Refine Rust if you’re Normal-obsessed; Polar Star for Abyss elite status.
Pitfalls to Dodge and Pro Tips for Peak Play
Common slip-up: Stretching Rust to a full 30-second melee, which tanks your 45-second CD recovery – fix it by capping at 9-11 seconds for 15-17s CD, fitting two melees per rotation. With Polar Star, stack fails? Pre-load with Ranged NA/CA before E; watch those icons for +48% ATK. Rust’s Charged penalty? Ditch it in combos (mN3C stays neutral, +10% stamina efficiency, tiny DPS dip); weave in 1-2 for Polar Star stacks. Rotation blunders like skipping Riptide app? Hit Charged or C4. Low ER (aim 170%+)? Start Ranged Q for the +20 refund, team with Favonius.
Group mobs for quadratic scaling. Keep 1-1.5 stamina bars ready. C4 auto-Slashes every 4s stretch things out. With Rust, skip C4+ if auto-Slash favors Skill weapons; Polar Star turns you into a hypercarry monster.
The Bottom Line: Pick Your Poison
Go Polar Star for endgame max damage – it’s BiS, S-tier for clears. R5 Rust? Your budget hero at 85-90% efficiency, perfect for casual or early-game grinds. Rust edges F2P/low-investment single-target without Charged; Polar Star rules competitive Abyss with full-kit magic. By spender type: F2P sticks to Rust/Hamayumi; low-spenders grab R5 Rust or Viridescent; whales chase Polar Star + C1/C6 (resets Skill CD after Burst, ER 155-225%). Long-term? Polar Star adapts to meta shifts; Rust plateaus without 5-star CRIT help.
FAQ
Is R5 Rust better than Polar Star for Tartaglia?
Nah, Polar Star edges it with 10-15% higher DPS in full rotations, thanks to 33.1% CRIT Rate, +48% ATK stacks, and +24% Skill/Burst DMG. Rust’s +80% Normal gets countered by -10% Charged and zero Riptide love. Still, Rust nails 85-90% efficiency in 9s melee sans Charged – ideal for F2P.
How much damage does Polar Star add to Tartaglia?
It bumps overall DPS by ~15%, like jumping from 13,200 to 15,000 total Hydro DMG in a 24s Vaporize cycle, via +48% ATK (four stacks) and +24% on Riptide Slash/Burst. Melee combos get +22% with full uptime from those independent hit triggers.
What is the best weapon for Tartaglia in Genshin Impact?
Polar Star takes #1 for main DPS, meshing melee Normals, Charged, and Riptide for peak AoE. Thundering Pulse (#2) is a strong Normal-focused runner-up; R5 Rust (#18) shines as the top budget 4-star for F2P, but chase 5-stars for S-tier Abyss runs.
Does Rust’s Charged Attack penalty hurt Tartaglia?
Yep, that -10% Charged DMG cuts into 20% of his kit in mN2C/mN3C combos, dropping Vaporize DPS by 5-10%. Counter with mN5C or neutral mN3C rotations to save stamina, though it limits 4pc Heart of Depth synergy.
How do you maintain Polar Star stacks on Childe?
In 9s melee, build four independent stacks: Ranged Burst/NA/CA upfront (+20 Energy refund), Skill for one, 2-3 from mN2C. Hit 95-100% uptime; track icons, recast Burst mid-rotation if swaps eat them.
