More Swords is the very first mod I ever created. It adds in the Elucidator and Dark Repulser from Sword Art Online, the Master Sword from Legend of Zelda, the Energy Sword from Halo, and the Lightsaber from Star Wars. They all have somewhat difficult crafting recipes since their rather powerful, just to keep things fair, but don't worry about whether or not you'll be able to get them in survival mode; it'll just take some time. Everybody enjoy the mod, and if you want to see the source code for reference, or whatever, here's my GitHub Page, and here's my twitter: @syntthetix.
