Campaign Challenges and Outpost Challenges cost 20 Energy when you claim their rewards. Sword Trials cost 20 to 60 Energy depending on the challenge. Open the activity from the map and read Claim Cost before starting. Natural recovery continues until the 300-point cap, so the practical routine is to spend enough for regeneration to resume, then save Pillow Powder for a specific first clear, upgrade, or deadline.
Natural recovery
1 Energy every 9 minutes
Current cap
300 Energy; about 45 hours from empty
Recovery item

Energy is not Stamina or Vitality. Energy pays activity claim costs; Stamina is used by crafting and gathering systems; Vitality is the white combat resource used by Mystic Skills. Older Chinese and translated guides may call Energy Mindpower, Heart Power, or 心力.
