I can count this among one of my favorite Terraria mods out there and I've used plenty of them at one point or another. There's just so many weapons for most of the classes at nearly any point in progression. I'm also liking how certain mods have new weapons added to their boss drops. I get the feeling of everything coming together and not feeling out of place with one another. I see you even started on armor, with the Starsteel set. I like when sets have multiple class options to make the whole thing feel more united with armor and weapons. If you can pull off more armors like this, that's just all the better. I like the extra Night and Terra weapons quite a bit too. I wonder if there will be more of them like whips and dart weapons. I'm still discovering new weapons in my different class playthroughs.
I do have mixed feelings about the slings and kestros. You're technically using them to throw stuff, so it fits throwing, but they also use ammo, which doesn't help criticisms of ranged and throwing being too similar. I haven't seen any that had auto swing as well. Most of the slings transform stone sling bullets into something else, so I hardly used the other sling bullets. I think the ammo and weapons have unique effects from each other.
With that said, I can hardly wait to see your take on summon weapons. I think there is two or so included already. I know summoner weapons tend to be the hardest ones to create and many modded ones do use the vanilla code for them. I look forward to the wiki being updated too since there is enough context in this mod that it can be difficult to keep up with it all, especially boss drops.
