If you have 3 heroes, there are still 4 army slots left. Enough space for a 4th level unit, a 3rd level unit, a 2nd level and a 1st. The reason why I only listed one 4th level unit, when there are always 2 available is because you do not wish to build 2 types of 4th level units, 2 types of 3rd level units, and miss out on the tonnes of 2nd Once in the area, Crag has to go southwest to a subterranean entrance. On his way, Crag will be ambushed by a hundred lizardmen and 40 lizard warriors. Past a sign and into the cave, Crag will find Marzeth, with 70 dread knights and 70 crusaders, as well as some undead troops. After Marzeth is defeated, Crag can collect the sword from his dead UmwPsb.
