Buy OSRS Rune crossbow
The rune crossbow is a one-handed ranged weapon in Old School RuneScape. It needs 61 Ranged to wield. It can fire all bolts up to and including runite bolts. It gives a +90 ranged attack bonus, which is the fourth highest one-handed ranged attack bonus in the game.
Because it is one-handed, you can use a shield at the same time. This is a big help when fighting dragons, since you can hold an anti-dragon shield. It also works well for player killing. The crossbow has an attack range of 7 tiles, or 9 tiles on the longrange style. Rapid style makes it shoot faster.
Many players use the rune crossbow for Slayer tasks and the TzHaar Fight Cave. It stays useful even in high-level content because it can fire ruby and diamond bolts. Broad bolts are cheap and easy to get, which makes it a smart pick for low-level players too.
The rune crossbow is a members-only item and weighs 6 kg. It can also be made with 69 Fletching using a yew stock, runite limbs, and a crossbow string. Stronger options include the dragon, Armadyl, and Zaryte crossbows.
