The following items can be unlocked by performing the actions below:

* Climb Leap Ability - Complete Rosa's mission "Monkey See, Monkey Do" in Sequence
  7 to earn the climb leap ability. With this ability, you can make longer jumps 
  while climbing, letting you grab hand holds that'd normally be out of reach.

* Disarm Combat Technique - Complete Mario's "Evasive Maneuvers" mission in Sequence
  5 to unlock the disarm technique. Disarms let you counter incoming attacks from 
  weapons that are normally too heavy to counter (like axes).
