This runes are used to make magic on a game called Oldschool Runescape.
Old School RuneScape is an MMORPG with adventure elements. It features a persistent world in which players can interact with each other and the environment. The basic mechanics are largely the same as RuneScape on 10 August 2007. The player controls a single (human) character and can interact with NPCs, objects, and entities in the game world by left-clicking or right-clicking and selecting an option from the object's right-click context menu. Users can gain experience points (XP) and level up individual skills, making their playable character more powerful in various ways.
