Grenwall spikes

Grenwall spikes can be obtained by trapping Grenwall. They can be used to make headless arrows after feathers are attached to them, or they can be sold to the hunter stores in Yanille and Nardah. They can be sold to Aleck (hunter shop in Yanille beside pet shop) for 100 coins or less. If the spike is used on Leon, he'll say that the spike can be used in slayer once he's completed the hunter crossbow. This suggests that there will be a future update involving Grenwall spikes.

Grenwall spikes are used to make Extreme ranging potions. Their price skyrocketed for a while in November 2009.
