Zitat von Cherry
You can.
However, if you do anything with one of these commands which does not revive at least on of the party members, it will trigger the Game Over (so be careful even with reviving, because attempting to revive a hero which is NOT in your party can also trigger the Game Over!).
The reason is that the RM designers didn't complete their thoughts on this one. They have a "check if everybody is dead and trigger Game Over in this case" check after any of these event commands has been processed. Normally, this would make perfect sense (well, not for all of the commands - why could changing EXP ever cause a Game Over? - but the reason is that most of them are handled by the same internal function and this function does the check at the end) if a dead party would be disallowed - but it seems like they didn't unambiguously specify that: On one hand, a dead party is considered disallowed becausing killing the last party member (e.g. using the Change HP command) or removing a party member and leaving only dead heroes in the party will trigger a Game Over (that's why this check is there). On the other hand, ending a battle with a dead party is allowed (and that's a good decision, otherwise event battles with a "defeat" handler wouldn't work).
This is why it's such a mess.
