[Ace]

As a side note, for some things, the "action" attribute will update too slowly to be useful. Originally, mudras/ninjutsu used this as the primary check, and it is very safe, but very slow however, since the "action" takes a while to catch up, and can also at times provide a false positive for cast verifications. This is not to say it couldn't be used for such things if you wanted, but, just know that it won't be perfect for all scenarios.
