Glacier
Glacier is an uncommon Defect skill that gains 7 Block and channels 2 Frost Orbs for 2 Energy. This is a premier defensive card that provides both immediate protection and passive ongoing Block from the two Frost Orbs. Each Frost Orb generates Block at the start of each turn (1 + Focus), making Glacier's long-term defensive value significantly higher than its upfront Block number.
Glacier is a cornerstone of Frost-heavy Defect builds. Playing it once sets up two Frost Orbs that continuously generate Block — with 2 Focus, each Frost generates 3 Block per turn, so 2 Frosts from Glacier give 6 Block per turn on top of the initial 7. It also contributes to the Blizzard counter (Frost Orbs channeled this combat). Upgraded, the immediate Block increases to 10, improving the turn-0 defensive value while keeping the same Orb-channeling effect.
