In Game Description said:
Leap Up: Allows you to easily and freely leap to your feet after being knocked prone.
Even with the text you quoted, Steele actually stands up after taking an action (but before any enemies), not at the start (technically speaking).
Proposal said:
When knocked prone, you automatically stand up as part of any action.
Normal:
Steele will remain Tripped until
Stand Up is chosen, which replaces the
Run button and consumes the turn.
Lift Off,
Booster Pack and
Levitate also remove Trip.
Leap Up:
Any action but
Wait will remove Trip for free, but will activate after the action.
Stand Up still takes the entire turn.
This makes
Stand Up something of a trap. Maybe don't replace
Run if Steele has
Leap Up?
I had assumed
Stand Up would be a free action but had always favored
Quick Draw.
Incidentally, the basic Tease attacks (Ass, Chest, Crotch & Hips) all have special text and are more effective when Tripped. With
Leap Up, Steele automatically stands afterward and so can't take advantage more than once/Trip,
Also, how does this work with the Overpass part of the Dhaal Feruze fight? Unless you can Fly, you need to be Prone for at least one turn.
