Promethium arrows

Promethium arrows are tier 10 arrows available while Dungeoneering. Known monsters to drop Promethium arrows are high levelled Forgotten rangers and the Sagittare and Skeletal trio bosses. They are more often spotted when dungeoneering in groups of two or more in large or medium maps.

They can be made by attaching Promethium arrowtips to Headless arrows with the fletching skill, at level 99, and can be wielded at ranged level 90. It is best to use tangle gum arrow shafts instead of other logs, because it would just make the same arrow and tangle gum branches are the cheapest.
