Sea Kiss is a Water Element Healing Element spell, capable of rapidly recovering from either physical injury or Spiritual Power damage.
After experiencing the war on the Beastman Plane, Duke realized the importance of this aspect.
No one can guarantee their survival, nor can anyone guarantee they won't get injured.
In plane wars, getting injured is common, and if you can't recover your combat power in time, it's easy to lose your life in a foreign land.
Duke has always focused on offense and defense, and most of his spells are of these two types. With Sea Kiss, he has filled the gap in this type of spell.
Another spell, Earth Spring, is an Earth Element Support Type spell, and its function is to recover Magic Power.
Earth Spring is a passive type of spell; as long as any part of the caster's body is in contact with the ground, it can continuously, albeit slowly, recover Magic Power.
