The More Manticore mod for The Witcher 3: Wild Hunt will change the look of all the armor and weapons in the game to a customized version of the Manticore set. This consists of level 1 chest and gloves, level 2 pants and boots, and level 2 swords. 

The appearance of the items will change immediately upon installation of this mod. All items will keep their vanilla stats. This applies to items looted, bought, and crafted. The visual changes will occur immediately upon installation of this mod and will revert back immediately with the removal of this mod. This works on both the original and the Next Generation versions of the game.
