Maybe you should just google for "Terraria Mob Spawning mods" or something like this. Also: Instead of creating a second thread because of A TYPO, you can ACTUALLY EDIT THE TITLE OF THE THREAD AFTER CREATING IT. Please, consider doing this next time. Thank you. Have a nice day.
People, maybe someone knows the name of the mod, which has two cool katanas with interesting mechanics. One katana was doing a dash or something like that
P.S. I found this mod, it's called Weapon Out, it has two cool katanas Raiden and Onsoku
