Frost vs Hydroid
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.
- Hydroid's pitch (“Hydroid summons the power of the ocean depths”) isn't what you're missing — Snow Globe is.
- Your builds lean status effects and Frost's passive extends that plan.
Pick Hydroid if…
- You want the squad gap filled by Hydroid's vibe — Hydroid summons the power of the ocean depths.
- You'd rather build around Plunder than live in Frost's Snow Globe loop.
- Your builds lean status effects and Hydroid's passive extends that plan.
Verdict
Both fill the Tank / Defense lane. Lean Frost for status-duration amplification and Snow Globe; lean Hydroid for status-duration amplification and Plunder. Mission Usefulness is a wash — decide on kit feel and passive, not the rating table.

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

- Your favorite clear starts on Freeze and ends on Avalanche — Frost is built for that arc.
- Hydroid's Plunder loop asks for a different muscle memory than you want to practice.

- Potato + Forma budget this month has Frost's name on it.

- Even after Helminth, Tidal Surge and later abilities are still the reason Hydroid earned potato.
- Your endgame loadout screen should show Hydroid before it shows another same-role experiment.
