The Spinebeam longbow is an item released with the Dungeoneering skill. It is slower than its counterpart, the spinebeam shortbow, though it provides reasonable defensive bonuses that the shortbow does not. It requires a Ranged level of 40 to wield, and a Fletching level of 41 to be made.
This bow can be obtained as a drop from Sagittare and forgotten rangers, or by fletching spinebeam branches. It can also be received from a starter kit in a low complexity dungeon if the player has 60+ Ranged. It is the most accurate free to play bow in Dungeoneering, tied with its shortbow equivalent.
As with all longbows in Daemonheim, the Spinebeam longbow is treated as a shieldbow by the game, allowing abilities that require a shield, such as Rejuvenate, to be used.
