So... I was fed up with dieing against the gargoyles and decided to check out the preceding areas. In the city of undead (before the taurus boss) I found a cliff, directly beside the stairs leading up to the tower.
To my dissatisfaction I wasn't able to get into the hole in the wall below the cliffs and died. Now my posessions (which is a not inconsiderable amount of souls) are lieing there, easily accessible on the cliff.
But as I see it there's no way to get back up from that cliff without dieing from the fall...
Is there any way I can recover my posessions from there?
