Maplestory Myths - know any?

No no no, it's not an actual cooldown that tells you you can't use it. It's just that after each BS cast, you can't use it for a small period of time. It's definitely not the delay because the delay is <900 ms, yet it takes over a second to cast if you're spamming it. However, it has its normal delay when you chain it with BoT (for example).

Oh yeah. Then it stays the same in Justice.
