Skill Priority
Battle Skill > Combo Skill > Ultimate > Basic Attack
Battle Skill is the shield and Protection opener. The first successful block extends duration and returns extra SP. Recast costs 0 SP, deals Nature DMG, and applies Nature Infliction. Guard and Infliction both sit here, so raise it first.
Combo tosses a giftbox heal when the controlled operator is hit. That is the sustain core, so level it next.
Ultimate opens three big giftboxes. Bomb or handicraft come out, and a special gift can apply Arts Susceptibility. Time it with the carry burst window.
Basic Attack comes last.
