This took me about 10 minutes after failing repeatedly since launch I decided to leave the game calm myself and try again, hey presto fresh eyes and clear head had me up in no time keep trying guardians Edit: seems people are still having trouble do not hug the walls this is sure death, stay close to the edge and look above before you jump hit detection seems to be about a foot above your head even with no obvious rocky overhang, most importantly have fun jumping off when you make it
