Praksis The Defiled Solo Boss Fight | Operation: Seraph's Shield (Destiny 2: Season Of The Seraph)
The Witness has resurrected Praksis from the Deep Stone Crypt raid. Run around getting the Suppressor buff and shooting Praksis under the balls - then blow up the 3 drones to lower the shield and do damage. Trinity Ghoul does a lot of work in this encounter :)
