Stellar Blade has a lot of collectibles for players to discover, with most of them acting as crafting material for weapon and gear upgrades. As players explore the world of Stellar Blade, they are likely going to come across a variety of different ways to obtain these necessary upgrade materials, such as from supply boxes, damaged car hoods, and even the bodies of fallen Airborne Squad members. Additionally, Stellar Blade features a type of enemy machine that collects rare relics that will be useful to players, seemingly drawing inspiration from Diablo 4's Treasure Goblins in their design.
