Hello! Bit of an argument over a hypothetical situation on a server I'm in, I'm going to send in an email to the FAQ address as I don't see it specifically answered anywhere: if a unit with a 'fight again' ability (e.g. Chaos Chosen) charges then fights, can it be selected to 'fight again' with the relevant ability if they ended up outside of 3" 'engagement range' of an enemy unit after the first fight?
Just in case it isn't clear:
Chaos Chosen charges successfully in the Charge Phase
Selected to fight in the Fight Phase, piles in and kills all models within 3". Unit states they will use 'Heralds of Ruination' once they've fought.
When units are striking last, Chaos Chosen fight again and pile in 3" (potentially to more models which they can fight).
Is this allowed?
