Hard Mode Bridge Crotas End - (Volt Method): http://youtu.be/W5djWlu0f2w You can do the raid with your lvl 30s :) super easy by doing it this way. The lamps, bridge, and the deathsinger. I have a video of the deathsinger. It makes more sense on that video if you can't under stand the volt method. Volt method can only be done on crotas end not vault of glass. Also it can not be done on crota because after beating him it gives you the loot.
