F2P Duo Builds That Actually Work – No Whales Required
Let's build 'em right. Saber rocks 4pc Wavestrider Captain (CRIT DMG/ATK% focus) paired with Firmament Frontline: Glamoth (that sweet 135 SPD DMG kick). Aim 70-80% CRIT Rate, 120%+ CRIT DMG, 135+ SPD, 2500+ ATK. Stats: Body CRIT Rate; Feet SPD; Sphere Wind DMG; Rope ATK%.
Archer? 4pc Genius of Brilliant Stars (Quantum DMG + DEF shred) + Rutilant Arena (CRIT Rate/Skill amp). Hit 100% CRIT Rate, 150%+ CRIT DMG, 2600+ ATK. Body CRIT Rate; Feet ATK%; Sphere Quantum DMG; Rope ATK%.
Trace priority: Saber Ult > Skill > Talent > Basic. Archer Skill/Ult > Talent > Basic.
Saber LCs shine with On the Fall of an Aeon S5 (64% stacking ATK% + Break DMG – 75-80% of her sig performance); alternatives like Under the Blue Sky, A Secret Vow, A Trail of Bygone Blood. Archer loves Cruising in the Stellar Sea (CRIT Rate + ATK% post-kill), Swordplay (DMG stacks), Baptism of Pure Thought. Her Technique? Battle-start AoE at 200% ATK +1 Charge.
Farm plan:
Prioritize CRIT Rate Bodies.
Lv80 with collab mats.
Test in Simulated Universe. (Pro tip: SU's your relic sandbox.)
Off-Meta Teams That Carry – Hypercarry Vibes
Saber Hypercarry: Saber + Remembrance Trailblazer (True DMG/SP gen), Tingyun (ATK/Energy buff), Lynx (taunt sustain). Archer SP machine: Archer + Hanya (SP funnel), Remembrance TB, Gallagher (SP+ heal).
Stage 10 First Half: Archer, March 7th (Imaginary shield), Asta, Lynx. Quantum/Fire weak – clears in ≥10/20 cycles, zero downs.
Stage 7 First Half: Archer, Trailblazer (Ice), Asta, Lynx. Quantum weak spot.
Stage 10 Second Half Saber squad: Saber, Sunday, Robin, Permansor Terrae. F2P swap: Dan Heng, Trailblazer, Yukong, Permansor Terrae. Physical/Wind AoE focus.
Why it clicks? Saber's post-Ult AoE Enhanced Basic shreds waves. Archer's single-target FUA dumps +1 SP per ally hit. A2 Archer? +2 team SP cap. Phase buffs: +40% DMG to unit + summon; cycle start True DMG +1/ally summon (max 2).
Team tips:
Rem TB for advance/CRIT/True DMG.
Hanya/Tingyun SP juice on Archer.
Lynx/Gallagher keep you alive.

Nail the Rotations – Scripts for Burst City
Saber stacks Resonance (3 ally Ults/2 Enhanced Basics = 8 Energy/stack, up to 360 for Ult). Enhanced Skill burns stacks for full Ult energy + DMG boost; post-Ult AoE Basic; Mana Burst +1 SP. At 135+ SPD: Stack → Enhanced Skill → Ult (AoE glory) → Enhanced Basic → Mana Burst.
Archer? Skill (Caladbolg II: 180-360% ATK Quantum, +60-100% DMG x2, 5x chain/SP gen) → Ult (600-1000% ATK +2 Charges, max 4) → Talent FUA (100-200% ATK +1 SP/ally). Manual everything – A2 adds +2 SP.
SP stays positive with Hanya/Rem TB. Ditch auto.
Saber: 3+ stacks → Enhanced Skill → Ult into AoE.
Archer: Hanya/TB advance, dump 5 manual Skills → Ult → Talent.
MoC Stages 7/10 – Floor-by-Floor Domination
Stage 10 First Half: Prioritize Archers of the Dark Sun Gryphon (AoE threat; killing 'em chunks Gryphon HP). Dispel Oronyx Marks on Moonlit Pegasus (2 stacks Quantum DMG; Ult spam; dodge Cocolia Ice Edges). Archer team: ≥10/20 cycles.
Stage 7 First Half: Nuke Everwinter Shadewalkers first (blocks their ATK buff). Cleanse Guardian Shadow Bans. Archer chains bosses; Saber AoE mulches waves.
Wave clear: Adds before elites. Archer boss chains; Saber wave blender.
Per stage rewards (7/10): Lost Crystal x2, Lucent Afterglow x8, Traveler's Guide x2, Refined Aether x1, 10k Credits.
Pitfalls I've Seen – And How to Dodge 'Em
Saber flops if SPD dips under 135, CRIT DMG outpaces Rate, or Energy Rope sneaks in. Archer? SPD Feet (nope), CRIT Rate <100%, SP fumbles, auto-battle. E0 crushes; Archer E1 adds Skill x3 +2 ally SP.
Fixes:
135+ SPD on Saber Feet.
Manual Archer chains + Hanya.
CRIT Rate Body, always.
Flex slots: Gallagher (heal/energy), Pela (debuffs), Tingyun/Lynx.
(Editor's take: Auto is the enemy – manual feels clunky at first, but those cycles? Chef's kiss.)
Benchmarks That Prove It – Real Numbers
Saber E0 On the Fall of an Aeon hits 75-80% of her sig LC in AoE MoC (data from optimized clears). Archer E0 bosses near-perfect single-target with free sig. S+ MoC DPS ranks; Saber bursts every 2-3 turns at 135 SPD.
Targets:
2500+ ATK Saber AoE.
2600+ ATK Archer FUA.
Zero downs, 10+ cycles spare.
