Chill

Chill is an uncommon Defect skill that channels 1 Frost Orb for each enemy currently in combat for 0 Energy. In a fight with 3 enemies, it channels 3 Frost Orbs for free — providing 3 slots of passive Block generation. As Frost Orbs passively generate Block each turn (scaled by Focus), free Frost channeling is consistently valuable in multi-enemy encounters.

Chill is a premium card in group fights, especially in Act 1 and Act 2 where multi-enemy encounters are frequent. Channeling 3 Frost for free can provide 3-6 or more Block per turn depending on Focus, which adds up to significant mitigation over several rounds. In single-enemy fights it's just a 0-cost 1-Frost channel, still acceptable but less dramatic. Upgraded, it channels 2 Frost per enemy, doubling the value in group fights and making it one of the most efficient defensive cards available.
