Soft tissue is a material item in Valheim. Its in-game item ID is Softtissue, which you can drop into the console with spawn Softtissue to give yourself one — append a number like spawn Softtissue 50 to spawn a stack. It still fizzes softly with ancient memories. The spawn command requires cheats — enable them with devcommands after opening the console.
