Okay, this has come up a couple of times in the last few games against a Necron player with an Overlord on a Catacomb Command Barge. His Barge declares a charge on my unit. Due to insane luck on my part, I manage to destroy his barge on overwatch. Here's where the question comes in: do models that get their chariot destroyed during Overwatch also get to charge in that same phase? Here is the order of events for clarity:
1. Overlord on Barge declares charge against unit.
2. Unit overwatches, destroys chariot.
3. Overlord disembarks from open-topped wreck as normal
Here's where the issue arises:
4. Can the Overlord declare charge as it is now a separate unit and not prevented from assaulting due to Chariots being open-topped (i.e. Assault vehicles)? As a side note: could the rider charge a different unit if in range as well?
In essence, is the chariot itself charging, or is the model on the chariot charging? The model certainly fights and can be killed, but what is exactly charging here? The rules seem to say that the chariot declares the charge, but the rider fights and can be killed. But if the former rider charges too, isn't that model attempting an assault twice in the same phase? So far, we've just rolled a die for it, but I think a better solution is required in the long run. I can kinda see the strange rules logic behind allowing a second charge, but at the same time, why would getting your feet blown out from under you allow you to charge in the same phase?
