1>Does Vortex of Return work on all units on the battlefield or only those under the command of the caster?

2>Ritual of Rebirth says it doesn't work on undead or lifeless units and makes a dead hero into a lifeless undead mummy, but Ritual of Death also says it can be used on the same unit multiple times. So it won't work on undead/lifeless heroes, except mummies?

3>How are new afflictions determined if a unit already has an affliction so for example, unit already has chest wound & gains a new affliction...
a>roll for new affliction determined to be chest wound so no new additional affliction since you cannot have 2 chest wounds.
or
b>new affliction determined to be chest wound and since you cannot have 2 chest wounds reroll for a different new affliction.

4>Does "Heal Units" and "Requires Lab to Heal" work for all units in the province including those patrolling outside a castle or only those inside the castle?
