Just went through a War on Skywatch. At first? Urzok took normal damage, got his shields back immediately, took more damage, got more of his shields back... Then he did something I've never seen before. While in the thicket of combat (i.e. me taking cover from Hive and Fallen Majors and Ultras while taking pot shots with Murmur) I saw a registered hit I could not believe. 19 shield crit. From a 331 Murmur, Arc. For those unaware, if you hit a shield with a corresponding energy type it is weak to, you automatically do additional damage to the shield only. I don't care how strong an enemy gets, but to see that, rinse and repeat once I respawned due to a hive major setting it's poison and void blasts on me, I ran straight for him. Sure enough. I did a MM on a ruler stick damage to his shields after a full clip of eidolon ally and a blast from Murmur. The guys shields are impenetrable. @Bungie- Challenge Accepted. Who else is going to kill that son of a bitch?
