Blizzard
Blizzard is an uncommon Defect attack that channels 2 Frost Orbs and deals damage equal to the number of Frost Orbs channeled this combat times 2, for 2 Energy. The damage scales with the cumulative Frost count across the entire fight — the more Frost you've channeled total, the higher the multiplier. Early in a fight it may deal modest damage, but in a prolonged combat or with many Frost channels it can hit enormous totals.
Blizzard is a scaling powerhouse in Frost-heavy Defect builds. It pairs naturally with Glacier, Chill, and any Frost-generating power, since each channel adds to the running count that Blizzard checks. In a deck designed to channel many Frost Orbs, Blizzard becomes one of the highest-damage cards available. Upgraded, the multiplier increases from 2x to 3x, dramatically raising the ceiling on late-game uses and making it a defining win condition for Frost-focused strategies.
