Frost vs Zephyr

Same Tank / Defense fantasy — which tank kit fits your squad and mission rota?

TL;DR — Quick Pick

Pick Frost if…

  • When Frost steps onto the battlefield, enemies experience a chill — that's the Frost pitch you want on the roster.
  • This slot should feel like Freeze, Ice Wave, and Avalanche, not a reskin of Zephyr's Tail Wind, Airburst, and Tornado.
  • Your builds lean status effects and Frost's passive extends that plan.

Pick Zephyr if…

  • You want the squad gap filled by Zephyr's vibe — Command the power of the wind.
  • Frost's pitch (“When Frost steps onto the battlefield, enemies experience a chill”) isn't what you're missing — Turbulence is.
  • You're buying into Zephyr's passive — zephyr moves faster and falls slower while airborne.
Verdict

Both fill the Tank / Defense lane. Lean Frost for status-duration amplification and Snow Globe; lean Zephyr for Turbulence and Turbulence. Mission Usefulness is a wash — decide on kit feel and passive, not the rating table.

When Each Shines

Frost

  • Snow Globe carries mid-mission casts; Avalanche is the density payoff.
  • Status-heavy weapons in hand — Frost's passive makes those procs earn their keep.
  • Frost shines on objective holds that need a frontliner who can also clear.

Zephyr

  • Turbulence carries mid-mission casts; Tornado is the density payoff.
  • Mod focus stays on match the priority to your main ability so the cast loop doesn't fall over mid-rota.
  • Defense tiles where Zephyr's survival tools stay online under Steel Path pressure.

Mod Scaling Focus

Frost

Match the priority to your main ability — Strength or Duration first for most kits, then Efficiency, then Range.

STR
Raises damage and effect potency across Frost’s Strength-scaling abilities.
DUR
Extends channeled / timed effects — often comfort on Frost if the kit leans on buffs or zones.
RNG
Helps radius / targeting tools. Dump it if Frost is mostly self-buff or exalted weapons.
EFF
Keeps ability uptime comfortable, especially on longer Steel Path missions.

Who Should You Pull?

Frost
Pull Frost if…
  • Status duration is how your weapons scale and Frost extends that plan for free.
  • Your favorite clear starts on Freeze and ends on Avalanche — Frost is built for that arc.
  • Zephyr's Turbulence loop asks for a different muscle memory than you want to practice.
  • Vazarin on the aura slot matches the school you're already building weapons around.
  • Potato + Forma budget this month has Frost's name on it.

Zephyr
Pull Zephyr if…
  • Turbulence into Tornado is the cast story you want to master — not a random subsume mashup.
  • You'd rather specialize hard into Turbulence than stay generic in the Tank lane.
  • Skipping Frost frees a craft slot — you'd rather finish Zephyr properly.
  • Open-world and bounty pacing still feel good on Zephyr, not only endless survival tiles.
  • Inventory space / foundry queue: Zephyr jumps the line over another Frost craft.
