The rules are fairly simple.

You show up with nothing but blessed items. You may use your Siege Bless.

A small bag with items that might be of use to you will be provided.

If you are able to kill any of the monsters in the dungeon, you can keep and use anything that you loot from them.

You will be taken to a location which has a number of gates.

Each gate goes deep inside a dungeon.

Somewhere in that dungeon is a mage, who will give you a code-word.

The first person to make it back to the EM Hall with all the words is proclaimed the champion, and gets their name on a trophy that will be displayed at the reward hall.
