Scenario: My minion moves forward 2 spaces, first through a repair pad and then one space further. The next command is a stuck control to move backwards, so I end my turn on the repair pad - YAY! I get to repair one damage. Or two? Landing on the pad obviously heals a damage, but does moving through the pad heal a damage?
Repair pads trigger immediately when you step onto them. Thus, you don't have to stop on them. You would repair the Damage upon stepping on it the first time. Note that if you repaired the card that would make you go backwards, you won't end up going backwards as it has not triggered yet.
Scenario 3 - same situation for stepping on rune spots - does a mech have to end a command on a rune spot to activate it? Or does just moving over it via a move of 3 or 4 or whatever?
Rune spaces work the same way when they are triggering something.
