Here’s the one at Kiln, with the original in the background. There should be a new bonfire there from which to warp to the Dreg Heap. If you own Ashes of Ariandel and have defeated Sister Friede (and Ariandel), go and talk to the painting girl in the attic and then return to the boss room. Any end game level character of 80-100 should do fine. The pre-release blurb suggested level 125 for this DLC, which to me seems rather excessive. I played through with a melee-focused Dex (Estoc and shield) character, at around level 90. The rest will follow in Part Two, once I’ve explored a few more nooks and crannies, and written the thing up. It’ll help with directions, enemy types, items (mostly – I doubt I found every single thing), bonfire locations, and offer a few boss tips. Part One covers the entrance to The Ringed City DLC to the Dreg Heap boss. So, if you’re struggling with gatling laser angel creatures, or lost amongst the windmills of The Ringed City’s Dreg Heap, this guide should be able to help you out.
Even the wisest of Ashen Ones needs a little Dark Souls 3 guidance now and then.
