The chances of dying in this room are zero as you don't get hit at all

Dummy Room: The dummy room, well, contains dummies. It located east of the animation room or north east of the bank in the guild. To begin, just get cheap luminary gold into the room.

The objective of the dummy room is to whack the dummies with the right type of attack. The chances of dying in this room are zero as you don't get hit at all.

It is a circular room with some trapdoors around it. A dummy will pop out every now and then. Each dummy is unique and can only be defeated if you use the right kind of attack against it.

So I recommend you to bring weapons which have a variety of attack options such as scimitars. You can also bring many weapons so that you cover all the attack styles. So a scimitar along with a battle axe will be a good option.

You may only use melee armors; range and magic armors are not allowed. You cannot mix two different sets of armors and you cannot play the mini game if you don't have a complete set.

So you might lose a bronze armour piece each time you defeat it and I haven't lost a single piece of my rune armour after playing 10 games straight.
