Evaluation
"Did you get some perseverance after the seahorse marine beat you up into shape? That form of life is kinda cunning... The Sea Horse Sailor doesn't look threatening. Her Spear skills and Ice Breath will cause you damage you won't expect. She also has strong elemental resistance and most status ailments don't work on her. Since she is a Sea-Dweller, she is weak to Thunder and Earth. Sleep and Confusion are effective on her and it's always fun to see friendly fire. It's better to be a cheap shot than to fight her fair. Now go, Hero Luka! Give it your all! ...did that sound cute?"
