This mod gives you the Amulet Of Daylight(creative only) which you can use to get the sword of daylight, and armour. It is easiest to go into creative, get the amulet, then go into survival. You then need to hold the amulet, and right click with it in your hand. You will get the sword and armour. If there are any bugs, please let me know in the comments.
