Frozen Heart

Frozen Heart deals 5 damage and gains 5 Block for 1 cost with the Retain keyword, meaning she stays in your hand at turn end. This flexibility lets you save her for when you need defense or offense most. Both values scale at 0.75x, slightly below average.

Level 3 adds 1 Chill, and level 5 adds +2 Block. Retain synergy with Warding Scroll relic grants +2 Block for each retained card, providing passive defense just by holding her. Crystal of Duality adds +3 Block on attack and +3 damage on Block, making her dual nature very efficient.

Ice synergy triggers bonus Block from 2+ Ice cards. She fits well in Ice control builds that value flexibility and hand management. The moderate scaling is offset by the Retain value and consistent availability.

A solid utility card for Ice decks.
