Chilling Seal

Chilling Seal is a type B passive skill introduced in Fire Emblem Heroes. It is exclusive to Gunnthrá.

Overview
Chilling Seal is locked to Gunnthrá and cannot be inherited by any other unit. If Gunnthrá's HP is under 50% at the start of each phase, the enemy unit with the lowest Defense stat is inflicted with Atk/Spd-6. If two or more enemy units share the same Def total, the unit with the current lowest Health receives the penalty.
