Katrin is a frost wizard who excels at crowd control and critical hit damage scaling. Her ultimate skill Blizzard damages all enemies and applies a frozen status that prevents them from taking any actions for 4 seconds. Her active skill Ice Beam targets all enemies in front, deals bonus damage to frozen targets, and temporarily boosts her own critical hit rate. Her passive abilities create a critical hit system - Archive provides baseline critical hit rate and attack bonuses, while Amplification stacks critical damage bonuses each time she lands a critical hit. This makes Katrin effective at controlling enemy teams while building up her damage potential through consistent critical strikes.
