Continue down the hill to the right. Walk through the first puddle. When you reach the second pool of water, jump onto the dead body floating in the centre. Wait here for a few seconds and a shadowy figure will walk into the water on the right and die, allowing you to jump over to the other side.
Grab the body next to the water’s edge and push it to the right. Drop it into the hole to activate the crushing trap. Jump across the top of the trap to the other side.
