Hi,
Xerj's Dreadlisks are deadly hunters because they bypass the shields of their victims.
This is not true if dreadlisks fight a pancor.
The dreadlisks shoot the pancor's shields.
Skip the battle until only dreadlisks are alive. Select the pancor and watch his stats when the dreadlisk attacks. They attack the shields of the pancor.
