Maybe this is known, maybe this is common sense, but I found this myself and just wanted to share...
As you know, for some guilds the books in Kara are still a big help, and the difference in some cases between a wipe or a kill...
I was fooling around in kara and found a place where there are always books at the same spot ( or at least every X hours) so its easy to pick em up there... )
* First of all you need to have killed all the trash up to Aran
* Walk up the stairs towards the next trash ( the purple ghosts ) and look down
* Jump down facing the wall so you land on the ledge (pic is what you see when jumped down)
* run over theledge to the big ledge
* Loot & get summoned or jump down (best to let a priest or mage go since the jump is pretty high)
Not a lifesaver, notting special, justsomething nice to give a little bit of help
EDIT: srry it ain't a real exploit, but not an exploration neither, didn't know where to post it...
