Skill points and the skill tree
Defeating enemies, minibosses and bosses grants experience; enough experience yields one skill point and the gauge rolls over. Spend skill points in the skill tree at Root Nodes — that is where you unlock the Talisman spell styles (Qi Blast, Water Flow, Full Control), Breathing Exercise, and the perks that deepen your kit.
Tao Fruits
Tao Fruits are world collectibles that grant a skill point and, regardless of type, raise the Direct and Internal Damage of slashes, Talismans and the Charged Strike by 3% each. They are the main outside-skill-tree damage scaling, so grabbing them visibly shortens boss fights.
Computing Power and Jades
Your real “level” is your Computing Power, which starts at 2 and reaches 10 via Computing Units (treasure or Chiyou). Each Jade costs 1–3 CPU, so a higher ceiling lets you run more Jades at once. See the Jade CPU guide.
Ability unlocks
Key moves are not in the skill tree but earned at Anomalous Root Nodes: Tai-Chi Kick (Central Transport Hub), Charged Strike (Greenhouse), Air Dash (Factory Underground), Unbounded Counter (Factory Machine Room), and Cloud Leap (Four Seasons Pavilion, after the fifth Sol). Each unlock also opens earlier zones you could not pass.
The Sol Seals and the Council Code
Yi’s revenge goal is to slay the other nine Sols and take their Sol Seals. Collecting the full set (Knowledge, Equality, Discipline, Benevolence, Insight, Legacy and the rest) forms the Council Code that opens the path to Eigong. The boss order guide lists each Seal and its location.
Endings and post-game
At the Root Pinnacle Yi reaches one of two endings. After any ending, Battle Memories unlocks: a boss rematch mode where you refight 8 Sol bosses with all skills, Jades and equipment, at higher health and damage (boost largest on early bosses). The difficulty guide covers the mode details.
