Is the 'rush' action provided by the card an on going effect or once per turn thingie? What happens if vampire untaps (freak drive etc.) after Lunatic Eruption's mandatory enter combat action?

1. It's once per turn, do what you like.
2. On going effect, rush again.
3. Something else?

"Put this card" part makes rush-once-a-turn. "Must" part should make your vampire unable to do anything if she was blocked, since she did not enter combat "as a D action". If she hunted or was not blocked entering combat, she fulfilled the requirement and should be able to do whatever she pleases.

An unsuccessful attempt still counts as a "performed" action and "performing" is what the rule on mandatory actions cares about.

And here is the explanation (from the latest RTR):

Rulebook updates:

Terminology (11):

“During X, do Y”:
The “during X do Y” template is used in several cards. When this template is used, only one Y can be done per X with this card. For instance, you may move blood from your vampire to your pool with Vessel only once per untap phase.

Isn't lunatic eruption a mandatory action?

I think that since it's mandatory action (unless the vampire must hunt, you have to attempt an attack.

edit: you cannot burn that card with an other vampire of yours first, since mandatory actions are going first. If i interpret the rules correctly

After the attempt to enter combat, the vampire with lunatic eruption uses freak drive / helicopter etc to untap.

But since he/she has a mandatory action, and he/she already attempted that action, and still have some blood (so he/she don't have to hunt, he/she cannot attempt any more actions, the vampire is stuck

Am i right?
