Steel bolts (p+) are poisoned steel bolts. Due to the Evolution of Combat, they can no longer be made by applying weapon poison+ to these bolts; they are instead received as a drop from monsters in Tarn's Lair. Attempting add these bolts to a Tirannwn quiver or bolt pouch, or equip these bolts, causes them to automatically convert to steel bolts within the player's inventory as a cleaning cloth would. These bolts are classified as level 31 within the player's inventory, with no accuracy or damage visible.
