Just as another way of having fun after level 80 I’ve taken to skydiving in Rata Sum. If you go to the accountancy waypoint there are 6 places where you can jump/fall off right near where each ramp going up meets the floor.
At first I was just jumping off and enjoying the extremely long fall to the bottom of the ‘pit’, teleporting back (no armor damage from falling – free porting in the cities) and doing it again. But then I discovered that it takes real skill to fall, smack into an object and die, and have your body ricochet off and fall some more. It’s REALLY hard to ricochet off of two objects.
I’ve had such fun (and frustration) trying to ricochet my body off of the blocks and such down there that I thought it would make a good achievement, something along the lines of “Ricocheting Skydiver”, which to get would take ‘skydiving’ in Rata Sum until you hit a particular block/object, die, and your body ricochets off and falls to the lowest part of Rata Sum’s ‘pit.’
