Started experimenting with Fusion Grenades in iron banner, then advanced to more advanced play - Trials of Osiris! I had no idea how lethal, and was shocked on how many sure death situations I was able to blast my way out of! Just check out this short video. Must people say run firebolt grenades on warlocks but after watching this video, let me know what you think of the Fusion Grenade! This is my first video so its not the most polished!
