Hero's job in HT Battle

Well I am finally getting ready to go face HT for the first time, if the hackers have released the cave and we can get in that is. I was hoping that some one can direct me in what the Hero's tasks are when it comes to the battle. I would like to have a little forehand knowledge of what to expect, I am aware that some parties may have different battle plans than others. I just hate going inside completely oblivious as to what to expect.

TY
