Funilly enough this video showed up in my feed just 24 hours after I got the item while I finally picked up the game again and started just exploring places.
I know im pretty late on this. But im still in my first NG on my second character due to the fact that i just hate doing NG+ since i always get my ass kicked. Im already level 184 and at over 59 hours in. I also have a first character with 252 hours in on my first game as well at level 204. My first character with the 252 hours is name Scylla and my 2nd character is named Simon. Both Castlevania character names
Fwiw, stone of gurranq almost stunlocks Edgar. He'll dodge once or twice, but as soon as you hit him with one, your good until fp runs out. I imagine rock sling would be similarly effective
Im stumped how people work all this out. I used guides on NG+ and I can't believe how much i missed. They really need to address their lack of quest info.
I have literally gotten that gold sword 4 times. Across around 500 hours. It's not that hard to get. Just systematically kill everything. There is far more of those nobles they people think.
