The Tirannwn quiver 4 is a reward from completing the elite Tirannwn tasks given to you by Elen Anterth in the Max Guild Garden in Prifddinas, and can be retrieved from her for free if lost. It is an upgraded version of the Tirannwn quiver 3. It is used in the ammo slot and gives a Prayer Bonus of 4. Up to 20,000 ammo of a single type can be stored in the quiver. The quiver itself is protected on death but 100 ammo stored in it will be lost - these do not appear under the player's gravestone.
Up to 20,000 of any ammunition slot items can be stored for use when ranging with relevant weapons. Upon death, the quiver appears in gravestones or Death's item reclaim with a reclaim value equal to the ammo stored.
Teleport to locations in the elven lands five times per day: Lletya and Eluned's location (after The Light Within, you will be teleported to Islwyn instead who is at the same location)
Access to the mushroom patch between the Tyras Camp and the Poison Waste. This patch cannot be protected from disease (and does not benefit from the medium Morytania tasks disease-free mushroom patch reward), but will give double harvest if elite Morytania tasks are completed.
