So many of you have found out by now that Thunderlord has a hidden perk, for those that don't know, it has a chance to chain powerful electrocution bolts between enemies. I just got my Thunderlord last week from Crota, , I was doing some bounties and was at the "We've woken the hive" Dark Beyond checkpoint farming hive bounties when I realized every now and then Thunderlord would cause mass explosions with lightning bolts chaining between enemies, clearing a large amount at once! Not sure if it has to be precision kills that trigger it or if it is random, just thought I'd share that tasty tidbit with you all. :)
