The Dynamic 2/1 Combo
Once the shield is down, it’s time to handle your business. Have a second fireteam member shift focus away from handling the smaller enemies to delivering as much damage as possible to the boss. Now would be a good time for any Defender in the team to drop a bubble, especially if it has the Weapons of Light buff. This bubble will help keep the two focused on Valus safe, as well as cover the back of the one handling all of the additional enemies. Feel free to switch to Blessing of Light if you find yourself taking too much damage for the added protection.
The two guardians that are focused on the Valus Trau’ug should alternate fire. While this Prison of Elders inmate does have the ability to switch his shields, he still must follow the same rules as every other enemy in the game. If his shield is down, it will stay down as long as he keeps receiving damage. However, his shield regenerates pretty quickly, so making sure one of the two guardians is hitting him at all times is critical. While one player reloads, the other delivers a steady stream of fire. If you’re using a gun with a high rate of fire, control your output so that you don’t run out while your partner is reloading.
Keep in mind that he will try and hide behind his forces when his shield is down, and he moves very quickly.Just maintain your focus and you’ll be fine
