As characters level up, they receive a passive boost to key stats and earn power points, which let players customize their abilities. Every character has three power trees where they can allocate these points. Each tree usually emphasizes a specific mechanic or playstyle, like Iron Man's shields, Hawkeye's trick arrows, or Deadpool's firearms. As the character progresses, players unlock more skills to invest in and can allocate additional points into existing ones. However, each skill has a level requirement, meaning you can't add more points until that level is achieved.
