Radiant Aether (Japanese: 蒼の天空 Blue Heavens) is a special skill which debuted in Fire Emblem Heroes and is the personal skill of Ike in his Radiant Dawn and Valentine's Day incarnations. Radiant Aether allows the user's attack to bypass 50% of the target's Defense or Resistance, and heal the user for half of the damage dealt. Radiant Aether can be considered an even stronger variation of the Heroes iteration of Aether despite that skill not being a prerequisite, having an identical effect to Aether with a faster cooldown charge. Radiant Aether cannot be passed to other units through skill inheritance, making it exclusive to the Legendary Hero and Valentine's Day incarnations of Ike.
