Frost vs Hildryn

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 Hildryn's Balefire, Pillage, and Aegis Storm.
  • Your builds lean status effects and Frost's passive extends that plan.

Pick Hildryn if…

  • You're sold on Hildryn's fantasy (Strength is Hildryn’s virtue) more than another Tank / Defense option.
  • This slot should feel like Balefire, Pillage, and Aegis Storm, not a reskin of Frost's Freeze, Ice Wave, and Avalanche.
  • You're buying into Hildryn's passive — hildryn's full Shield Gate is high.
Verdict

Both fill the Tank / Defense lane. Lean Frost for status-duration amplification and Snow Globe; lean Hildryn for Haven and Haven. 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.

Hildryn

  • Haven carries mid-mission casts; Aegis Storm 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 Hildryn'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.
