Your posts about DS3 inspired me to do a new run since it's been a while.
I started with the thief class and have only used the bandit knife. It's not a bad weapon, but the range is abysmal and is teaching me to play a little differently. Besides that I'm around level 70 and have been using the Grass Crest shield. My rings are Prisoner's Chain/Chloranthy/RFAP/Havel's.
I cleared all the mid and late game bosses yesterday, only NK and SoC left from the base game. Not decided yet if I'm going to do the DLCs with this build because of the knife range. Might switch over to a large club and give them a spank, though.
