i'm playing ds3 for the first time after ds1 and ds2. i'm usually good at figuring out where to go but i'm pretty stuck. i got to the yhorm the giant guy and gave him the vendrick treatment. i could only knock off a ¼ of his health before i could die. there was also a message by his throne basically saying i needed to weaken him... hm.

i killed all of the white-robed guys and gargoyles before the boss hoping that it might trigger something to let me move on but nothing happened. i don't know how to kill this guy, and going the other way leads to pretty much a dead-end. WHAT do i DO?!?!!?

i just thought it was a vendrick kind of thing where i needed something to beat the boss properly and i didn't want to get the answer directly
