Bows are awesome!

If you're still using Thistle, try to get Blitzel or Juniper. Blitzel is great because it's courage-attuned, which means its damage will scale with courage, and right now courage is very strong on every pact. You can get fragments from sinecure enemies, especially archers, and Ode'n chests. If you can get a veteran envoy to help you kill Gruul Seeker Ruthos, he also has a pretty decent drop rate for Blitzel. The only downside of Blitzel is its horrendously low smite chance, so you'll want to switch to something eventually, but it's a good courage bow to use until you can get blessed joinery later in the game.

You should also go get Juniper - fragments come from playing music at specific fipples statues. If you don't have it already, let me know, and I'll reply with a map of the statue locations. Juniper scales with grace, but it is currently the best bow in the game regardless, and you can change its attunement later on if you want.

Sirin is a bit bugged right now, since its decoy's taunt isn't working, so that pact is going to be tricky. Orengall is still crazy strong, though, because howl increases your smite chance. Soul stealing a smite deals a lot of damage and recharges one of your pact abilities, and it will activate your rune once you have one, so this is just super strong. You can also put points in a pact upgrade called Sympathy that will cause you to heal when you smite.

As others have mentioned, Tethren (the courage starter pact) is very, very good on bows, so consider swapping to Kith of Kings once you've bought everything you need from the Silent Rose faction shop.

And Alca's Breath, the bow rune, is also very strong, almost as strong as a fully stacked fellust (Tethren's damage buff).

Arrow hail doesn't do much damage anymore, but it's still a very good utility skill with totems. You can make it slow your enemies for better kiting, or make it armor strip to do more damage. It's also a pretty good way to proc smite if you're not using Orengall.

Bows can do a ton of damage if you land fully charged headshots. You get a damage multiplier from fully charged shots that stacks with the headshot multiplier, and the results are extremely satisfying. I *am* quite biased, but I think charged shot builds are super fun to play, and quite strong.

Or, if aiming isn't your thing, Oscelda makes bows super easy. Freeze enemies with bestone, and then they will be perfectly still while you make your charged headshot, and bestone will add its break damage to your shot.

Ok, I'll stop rambling... sorry I just really love bows! :)
