It doesn't have to be exactly like the vid shows though. I personally got it by using Demon Pull--->Enemy Step--->repeat. --- WHY SO SERIOUS!? O_o LET'S PUT A SMILE ON THAT FACE!!! >=] PSN: SHIN_MEGIDDO_X http://www.youtube.com/watch?v=lQi0Mv7kK_E
Need to be in a fight, juggle the enemy in the air and use his body as a step to get there. Anyway you do it is fine, as long as it's in battle. Launch an enemy, grapple to him and uppercut then jump to the platform of the golden key. Or launch the enemy and use the Triangle Triangle Pause Triangle Triangle attack of the Scythe, should also make you high enough to reach there.
There are multiple way, but it needs to be in battle. --- Aion is just like all other WoW clones, I mean, the Mage in Aion has a Fireball spell and can make Portals. WoW ANYONE??? - Aion Boards
There is an easy way you need angel pull and jump. Pull a rage up then jump pull and repeat until you get high enough then Glide over using Angel Boost. There is one in 12 or 13 for a lost soul same idea but a butcher can hit it as well. i restarted the level after I found it later and was planning to use the angel jump to get it when the butcher Saw launched vertical and took it out for me. --- I have an answer to everything whether its a good answer is entirely irrelevant
