Help a newbie out!

[Targa]

I guess this thread is going to rapidly fill up with everything I don't know about this game.

I was just reading Apoger's thread, and in part of it he states: "Upon entering combat cast Astral Tempest - Body Ethereal - Personal Luck - Astral Shield - Twist Fate - then "cast spells". Make sure you have at least 4 pearls on the Golem for the castings".

Since you have no battle control during "host", how can you cast specific spells in a specific order like this? Or for that matter, take specific actions? I know you can "set orders". Do these orders "stack sequentially" if you continue to issue new orders? Thnx.
