Buy RS3 Mithril arrowheads
Mithril arrowheads are items in RuneScape 3 used for training the Fletching skill. At level 45 Fletching, you can attach them to headless arrows to make mithril arrows. Headless arrows are made by adding feathers to arrow shafts. Each set of 15 arrows made gives 112.5 Fletching experience, so a big stack of arrowheads can help you level up fast.
These arrowheads also tie into the Smithing skill. At level 30 Smithing, players can make them from mithril bars, and each bar gives 75 arrowheads and 120 experience. Buying them ready-made saves you that work.
Mithril arrowheads are stackable, tradeable, and weigh nothing, so they take up just one spot in your bank or inventory. They are also free-to-play, which means any RuneScape player can use them, not just members.
Players who train Invention can disassemble them too. Taking apart 50 arrowheads can give stave parts, head parts, crafted parts, or rare precise components.
If you want steady Fletching XP or a supply of mithril arrows for Ranged training, a stack of mithril arrowheads is a simple and useful buy.
