So a passive skill might be to always know what time it is, or where you've been? 

And a combination skill might be something within arm's reach unlocks when you snap your fingers?

A passive skill is something that gives you a constant benefit. So, yes, technically you could have a skill that tells you the time of day, but then, you could just buy a magic watch or hourglass... As for the map-idea, that's not quite the same thing givenn that it'd be INCREDIBLY inconvenient to ALWAYS have a magic mental map in your head, pointing a mental arrow at the little white blip on the graph-paper background and going: YOU'RE HERE! While simulataneously adding small notes and funny descriptions of places you''ve been.
So, yes to clock, no to map.

Conditional Skills work like that yes. Of course, the condition has to match the effect that the skill produces. You're not just gonna be able to Thanos-snap your enemies to death, but you [i]could[/i] snap your fingers to create a candle-sized flame for a minute or so, at no magic cost.
