We do not fear cold.

Karuka, reverted to human form so the game properly recognizes blocks, endures a wintry onslaught.

For reference -- those 'cold damage' ticks should be doing 180-300 damage per tick. Log shows that, when they aren't ignored (thanks, Shield Deflection!), a combination of Block Energy / Magical Resistance Rating / Fireshield are bringing them down to the 60-90 point range, before factoring energy resistance.
