Does immobilized stop the hero ability of O&R that turn or are the completely unaffected by it?

It depends on the time O&R gets immobilized:

If he is immobilized in step 1.I. "Start of turn abilities" of his turn, he may decide the order in which start of turn effects resolve. He may choose to gain movement points after getting immobilized and may use them in his turn. I am actually not sure if an effect exists that can immobilize a hero in step 1.I.

If he is immobilized at a later step in his turn and he still has unused movement points, these movement points are lost as soon as he is immobilized.

I know it's a bit of a weird topic, but I've learnt to realize that Descent is a board game before being an RPG.

As per the rule says;

"You cannot perform move actions or suffer (stamina) to gain movement points"

It doesn't prevent any other way of being moved around, or any other way to gain movement points. Like O&R ability, or allied class skills that could allow you to move.

Amuny, exactly.

Sadgit, I'd be willing to bet there's a quest out there with a special rule, "If a hero starts his turn in a space on X tile, he is immibilized." That being said, I agree with your conclusion of how it would play out.

Can I ask why you see it this way? There's nothing on the Immobilized card that says you lose movement points and can't gain them. It only stops you from performing a move action or using fatigue to move. O&R's ability falls into neither of these conditions. So no matter when during his turn he receives the condition he would still be able to move.

What would be the proper way to use him in sludge spaces?

Proto Persona, there is a description in the FAQ that deals with "immobilized", and the idea is that when you become immobilized, you are forced to "end your move action." Regardless of whether you have a move action in progress, that instruction means you lose ALL unspent MP, no matter where they came from.

Indeed, the official FAQ is referring to a move action and does not really clarify what happens with movement points from other sources. However, this case has been addressed by an unofficial FAQ . I guess, I should have added this reference in my original answer.

Well that is definitely clear, but it sure does feel like the rulings actually made things even more complicated. The condition doesn't mention any of this or even seem to imply it. If the application of immobilized is meant to remove any existing movement points it really should be stated on the condition card.

Feels like this would have been a lot simpler if they had just used a movement point pool. Not the first time in Descent's rules that things were more complicated than needed though.

I agree. I think Immobilized would have been much clearer, and more in line with what it actually is, if when you acquired this condition, for that point on, through the end of your turn (or next turn) you simply COULD NOT VOLUNTARILY MOVE FOR ANY REASON.
