Hi Katzano,
You can try out the fights of the guards here:

damoria.bitmeup.com/guard.php

Just play with the level of the guard, the equipment, weapons and training and see what effect they have on the battles.
You have 2 teams with up to 3 knights each compete against each other. All you have to do is enter the combat identity of a knight from the game in the corresponding line.
You can find the combat identity on the knight overview page (top right, above the stats)
All knights can currently compete against each other. World 2 players can also compete against World 1 players.
Your own knights can also compete against each other. However, each knight may only be placed once in a fight.
