I was fortunate enough to find a great Dawn, but I do have it cubed too. IMO, it is much more difficult to find a great quiver than a great Dawn. It needs CHC, CDR, HA damage & AD ideally with a high enough multiplier for HA. That’s the unicorn. I push dual wielding with Dawn & Fortress w/Squirts. I prefer this over Valla’s & Dawn w/ FoT. I find I’m not killing anything with Valla’s & Dawn.
If I were you, I’d reforge Dawn until you get a decent one, but that’s just 1 opinion.
