Quick question.

If you draw a Mythos card with an "or" choice, can you choose an option even if that would do nothing ie: Could I choose to move monsters with hunter if there are none rather then the other option.

You have to be able to fullfill the or... I think...

If you can't do it, you can't choose it.

I'd say no.

I assume it is a forced revelation effect on a mythos card?

A forced ability is identified by a bold "Forced – " command. Forced abilities initiate and interact with the game state automatically at a specified timing point. Such a timing point is usually indicated by words such as: "when," "after," "if," or "at."

If a forced ability does not have the potential to change the game state, the ability does not initiate.

As I read it if that forced ability is not able to initiate it is not possible to choose it.

Even if its not a forced revelation, you always have to choose the effects you can fulfill. In the rare case that you cannot fulfill any of the effects in an "or" situation, the card simply resolves and is discarded. But you simply cannot choose an effect that cannot occur in favor of one that can change the game state.

The rule for this can be found under “Must”, on page 16 of the Rules Reference:

“If an investigator is instructed that he or she "must" choose among multiple options, the investigator is compelled to choose an option that has the potential to change the game state.

• In the absence of the word "must" while choosing among multiple options, any option may be chosen upon the resolution of the effect – even an option that does not change the game state.”

Thanks everyone!

Merry Christmas.

Note that changing the game state does not require you to be able to do the entire option, just enough to change the game state. If, for example, you must choose between losing an action or taking 1 damage and losing 1 resource, you can choose the second option even if you don't have any resources. You do what you can (take 1 damage), ignore what you can't do (lose 1 resource), and the damage is enough to have "changed the game state".
