Early Dark Torvus Bog key
Discovered by Ghost:
In Venomous Pond, there is a Dark Temple Key that you "need" Grapple Beam to get... Bzzt. Wrong! Near the Save Station there are 3 Ingsphere Caches. You will need to practice L-Lock Jumping before doing this simple trick succesfully. After looking as far down as you can, hop onto the biggest cache, and just jump to the key.
