My first arc run I just used hunters tools basically, and was able to defeat every boss, + chalice dungeons basically with a call beyond spam. It is kinda boring, it's just like run away, acb, run away, blood bullets, run away, heal.

The last couple arc runs I actually try to gem up my weapons and play it straight, using hunter tools as support. This I find to be a lot more satisfying. I think as the other poster said, the fire gig saw is a terror to beasts. Also the parasite is so good its broken, especially in CDs, very fun. At that point, just need a bolt weapon for kin type enemies and you can take on anything. Admittedly, is performance much different than a dex or quality build? Eh maybe a little? Playstyle is a little different. But the path through the game is very particular in order to stay strong enough with arc weapons, so it's kind of a different adventure than pumping points into stats. The CDs are no longer optional, since you have to hunt for and grind gems.

Ever play with the blood letter? I procrastinated playing with it for so long, but once I got the hang of it I did 3 playthroughs in a row with it. Very fun, and having to manage frenzy buildup adds a wrinkle to gameplay. With the cannon, its ridiculous!
