NUKAS'S PROFILE

Is there a way to make a skill usable only after a certain number of battles? Like, an "omg-oh-so-destructive-1-hit-ko" skill being available after x battles?

I might be a bit late but you can use the variable $game_system.battle_count to get the total number of battles.
Probably something like:

<restrict eval>
$game_system.battle_count > 200
</restrict eval>
