When a clear turn is initiated, if a model is exhausted, do they go to fatigued? Or do they remove all of it?

To rephrase it... If Iocasta is exhausted on my clear turn does she go to fatigued or to ready?

As Gomez says, the default is that each model recovers one fatigue. So an exhausted model would go from exhausted to fatigued.

However, you mention Iocasta... and it is worth noting that the Morituri has a ludus benefit that allows them to recover all fatigue instead of just one fatigue.

So the answer to your question is your first option - unless the models in question have Morituri benefits, in which case it is your second option.

Iocasta would clear all of it - IF she had ludus benefits applied to her. Which is not guaranteed that she will.

Sorry for being so pedantic, but when we are talking about wanting to play accurately by the rules, best to stomp out any potential for confusion by spelling everything out in detail.

(Any model can potentially benefit from the Will of Antony effect described above, it just depends on ludus construction.)

I think you should re-write the rule book including all the information from the rules section and submit it to walker if you make a Google doc I will help where possible.

That's a really interesting idea. Crazy ambitious - but interesting.

(Of course, now I have already started doing it.)
