My question is about Belthir's ability "Cry Havoc"

If I remember correctly, it states ' He may take a move action and then an attack action attacking very model he passes over' (he is of course a flyer) Is this action contingent on there being models to attack? In another word can he perform the Cry Havoc action if he cannot attack anyone?

The reason this has come up is that in the scenario "as the Wyrm turns"(Act Ii scenario) The players get to control Belthir and his abilities. It states in the rules that Belthir may take only 1 move action and 1 other non move action per turn. The players quickly discovered that a move action, plus the Cry Havoc action was a quick way to get a double move, even if they did not have any models to attack during the Cry Havoc action. Our group decided that this was allowable, however I am still not so sure. Interpretations anyone?

It's amazing the tactics people discover when this thing leaves the companies R&D department. lol Well, if the ability reads as you say and that he attacks any models he moves over, then I would take "any" to be from Zero to his move rate. So, yeah, he can fly and not have any models to attack. Otherwise there would be that stipulation in there.

Using Cry Havok on no models should be fine he takes a move action and then an attack action.

That said "performs a MOVE ACTION".

As he can only take 1 move action per turn he can't both take the move action from cry havok and do a normal move action in 1 turn. Abilities that just move the target would be fine abilities that grant a move action (syndreals heroic feat) would be restricted.

I'm not sure I understand the conflict here. Cry Havoc is a special action, not a move action, right? It says to take a move action, but that doesn't make it stop being a special action nor does it turn it into a move action. The rules say that a special action can count towards a monsters attack for that turn, but doesn't mention anything about it counting as a move action. So Cry Havoc should not count towards his move actions for that turn.

I'm willing to wager that at some point during development all special and heroic abilities were worded like this until this very confusion came up in testing. So instead of clearly defining how a special action is not a move action, FFG decided to simply remove the words "move action" from the cards but missed correcting this one. Wouldn't be the first example of inconsistent phrasing either.
