I have a question.
The rulebook states that a Hero causes a coexistence battle, even if unsupported, correct ?
However, the battle ends if there are no units (Heroes are not units, there is even an example in the rulebook) .
Now what happen in a coexistence battle with a Hero.
1 - No iteration is fought since the battle ends immediately
2 - 1 iteration is fought
3 - the battle goes on until one of the other ends of battle conditions is triggered ?
