use the witches bossroom lamp and head out to where the big executioner guys and the dogs are. There is a stone obelisk thing on the cobblestone path, touch it

There may be a location you can access in the forbidden woods that will help you... I don't want to spoil your fun though. If that's too non-specific I can give you another hint lol

you need the rune workshop tool for that, found after defeating an optional boss at the end of the hemwick charnel lane area. bfore the grand cathedral (vicar amelia bossroom) at the base of the stairs go left. caryll runes enhance the experience so much, good luck hunter!
