[Argitoth]

1. Once your pretender is dead you gain access to a "Call God" command from your holy and unholy priests. The more holy or unholy power a priest has, the shorter the time takes to bring back your pretender from the dead. In addition, the more priests calling your pretender, the shorter it will take for him to reappear. Pretenders may come back with battle wounds though.

2. After about 4 turns you will recieve a message something like, "The power of your prophet has returned..." or something. You may then appoint a new prophet.

3. Your troops don't need to be with your mage for the mage to summon units. There will be a note in the spell's description "Can only be cast underwater" or "Cannot be cast underwater". If it has niether, you may cast it on land or in water. There are multiple magic items to give your troops the ability to breathe underwater. Make sure when you try to summon something underwater you build a lab to do so.
