After Duke crawled up to the shore, he didn't put on the robe from his Space Ring, walking along the sandy beach bare-chested, wearing only shorts.
He glanced at the Skill Tree; the proficiency in Underwater Breathing had increased significantly.
But now there were already many skills on the Skill Tree, a bunch of skills waiting for him to grind the proficiency up.
[Deep Blue Tide Meditation Technique: Level 2 (678/1500)]
[Wizard's Mark: Level 2 (178/300)]
[Water Arrow Technique: Level 1 (81/100)]
[Water Shield Technique: Level 1 (75/100)]
[Underwater Breathing: Level 1 (421/500)]
...
Looking at this string of skills, Duke didn't plan to learn any other magic in the short term.
Just these spells were going to take him a lot of time to grind proficiency, and learning new spells would leave him without the time and energy to improve.
