Flins is a 5-star Electro Polearm user introduced in Version 6.0 from the Nod-Krai region. He brings a fresh approach as a Main DPS who uses new mechanics like Lunar-Charged reactions and “Manifest Flame form.” This guide breaks down his kit, strengths, weaknesses, best builds, team comps, materials, and tips so you can maximize his potential.

Strengths & Weaknesses

Strengths:

• Very high burst potential due to Lunar-Charged mechanics and his transformed state.
• Good scaling via ATK, Elemental Mastery (EM), Crit Rate / Crit DMG when built properly.
• Has flexibility: strong on-field DPS or can contribute via bursts with quicker rotations.

Weaknesses:

• Requires specific team synergy to maximize Lunar-Charged reactions, particularly with other Nod-Krai characters (e.g. Ineffa) to trigger Moonsign effects. Without them, his performance drops.
• Energy Recharge (ER) and managing his burst cooldowns / skill uptime are more demanding.
• Artifact and weapon RNG can make or break his output. If Crit stats or EM are low, his damage can suffer.

Best Builds: Weapons, Artifacts & Stat Priorities

Weapons

• Signature Weapon (if available): Bloodsoaked Ruins is often cited as his best option. Effect boosts Lunar-Charged reaction damage, Crit DMG, and helps with Elemental Energy recovery.
• 4-star alternatives:
  • Deathmatch – good Crit Rate boost.
  • Ballad of the Fjords – gives extra Elemental Mastery in multi-element teams.
  • Others that emphasize Crit / ATK are acceptable until you get his signature or a top-tier polearm.

Artifacts

• Best Set: Night of the Sky’s Unveiling (4-piece) is generally considered optimal. It gives Elemental Mastery via the 2-piece and has bonuses in its 4-piece that boost Flins’s Lunar-Charged damage, especially when reactions are triggered by party members.
• Transitional or Alternative Sets:
  • Gilded Dreams (4-piece): gives useful boosts to ATK plus EM, works if you don’t have ideal sets yet.
  • Mix sets if needed, but try to hit at least 2-piece for EM or ATK depending on your available gear.

Stat Priorities (Main & Substats)

• Main Stats:
  1. Circlet: Crit Rate or Crit DMG
  2. Goblet: ATK% or Electro DMG bonus (if possible)
  3. Sands: ATK% or Energy Recharge (if needed)
• Substats:
  • Crit Rate / Crit DMG
  • ATK%
  • Elemental Mastery (to enhance Lunar-Charged reaction damage)
  • Energy Recharge, especially if the signature weapon or certain passives don’t provide enough ER.
• Benchmark values (common targets among builds):
  • Crit Rate: ~ 60-70 %
  • Crit DMG: ~ 180-250 % depending on weapon / artifacts
  • ATK: as high as possible (2000-2200+ on top of base)
  • Energy Recharge: ~ 120-140 % (this can vary based on team and constellations)

Constellations & Passive Talents

• Constellations enhance his Lunar-Charged reaction damage, reduce cooldowns, and improve synergy with his Skill / Burst.
• Passives include converting ATK into Elemental Mastery up to a cap and party buffs tied to the Moonsign system (Nod-Krai regional mechanic) that further boost his damage under certain conditions.

Team Compositions

Flins performs best when paired with characters that enable strong reaction triggers, provide energy support, or enhance his Electro / reaction damage. Here are some of the recommended teams:

Best Synergy Teams:

• Ineffa + Flins + Aino + Yelan
  Ineffa offers strong Nod-Krai synergy and buffs, Aino for elemental application or utility, Yelan for Hydro reaction triggers. This lineup helps activate Lunar-Charged frequently.
• Flins + Hydro applicator + Buffer / Support
  If you don’t have Ineffa, pairing Flins with characters that apply Hydro (for Electro-Charged or reaction setups), someone who can reduce resistance or increase Elemental Mastery, and another that maintains his uptime (shield or heal) works well.
• Flexible / F2P setups
  Use more accessible supports and lower rarity characters, but make sure to meet requirements for ER, reaction triggering, and artifact quality. Can be viable, though performance will lag behind ideal builds.

Playstyle & Rotation Tips

• Use his Elemental Skill to enter the Manifest Flame form, then chain Normal / Charged Attacks during that period for maximum Electro output. Keep an eye on energy and cooldowns.
• Use Quick-Swap Burst (his special shorter burst) when available to maintain damage even when he is off-field. That helps if you need to swap for healing, shielding, or reaction triggers.
• Time reactions: Hydro users and supports that trigger Electro reaction should be built and synced in rotation so Lunar-Charged triggers are consistent.

Should You Pull / Is He Worth Building?

If you are a player who:

• Wants a strong Electro DPS with new and interesting mechanics
• Already have good artifact and weapon options and can meet stat thresholds (Crit, ATK, EM, ER)
• Have or plan to get Nod-Krai characters that improve his synergy (especially Ineffa)

Then Flins is likely worth your pulls. He brings something fresh to the meta.

If your roster lacks those supports or you are early in the game, he will still work but you may need to invest more in gear and team building to get him to shine.

Final Thoughts

Flins is one of those characters that scales well with investment and rewards players who plan ahead. With the right weapon, artifacts, and teams, his Lunar-Charged reactions and Manifest Flame form make him one of the more powerful Electro polearm DPS options in Version 6.0.
