What it does
Refrigerate changes all Normal-type moves the holder uses into Ice-type and multiplies their power by 1.2. Clean and simple: Normal → Ice, ×1.2, applied once.
One thing to get right immediately: Blizzard is already Ice-type, so Refrigerate does nothing to it. Aurorus has two separate damage tracks — Blizzard hits 100% accuracy in Snow weather by itself, and Refrigerate operates on Hyper Voice. They don't interact.
The math on Hyper Voice: base power 90, after Refrigerate that's 90 × 1.2 = 108 effective Ice-type power. In doubles, spread moves take a 0.75× penalty against multiple targets, landing at ~81 per target. That sounds modest until you factor in Ice's offensive coverage — super effective (2×) against Flying, Dragon, Grass, and Ground — four types that appear constantly in the format. Against a resisted or neutral target it's decent; against a Dragon- or Flying-type it ends the conversation.
Aurorus sits at 99 base Special Attack, which built properly reaches a solid output floor. Pair that with a spread move hitting both opponents and you get immediate field presence from turn one, no setup required.
Who runs it
Aurorus is the carrier, running Refrigerate in 74% of its Champions sets. Rock/Ice typing means it naturally sits in Snow teams — it can set Snow itself with Hail, letting Blizzard fire at 100% accuracy as a single-target backup, while Refrigerate Hyper Voice handles the spread damage. Two attack modes, one Pokémon.
How to use it
Hyper Voice is the primary output button. Use it almost every turn you're attacking — the coverage it threatens is wide enough that opponents can't ignore it. Blizzard fills in when you need a single-target hit with higher base power (110 vs. 90) and are already in Snow weather.
Speed investment on Aurorus depends on your team's structure. At base 58 Speed, it's slow — run it under Trick Room support for a free priority bump, or bring Tailwind support to patch the Speed issue and let it outrun more targets.
Against teams with heavy Dragon, Flying, Grass, or Ground representation, Hyper Voice turns into a two-for-one most turns — both opponents are weak, and you're taxing their HP simultaneously.
Tips & strategy
Steel-types eat Refrigerate moves for 0.5× damage. If your opponent leads a Steel-type alongside a second Pokémon, your spread Hyper Voice loses half its value on one side. Read the lead; sometimes it's better to pivot or use a different move rather than feeding a Steel-type a resisted hit.
Aurorus is fragile — Rock/Ice gives it Fighting, Ground, Water, Grass, and Steel weaknesses. It goes down fast if exposed to common coverage moves. Position it where it can spread damage before the opponent can target it directly, and expect it to trade rather than run long.
In Snow teams, Aurorus is both the weather setter and a damage dealer. That dual role means it's often the first target opponents want removed. Protect turns and positioning matter more than usual when your team's whole weather plan lives or dies on keeping it around.
