Zamorak arrows are a possible clue scroll reward from any level clue scroll. They were released on 4 August2010. After being shot, they will disappear, meaning that they cannot be retrieved with Ava's alerter. This is useful if you don't want to use the accumulator, since you won't be tempted to pick up arrows, although wearing the accumulator will still give its ranged bonus. Magic shortbow, Magic shieldbow, Dark bow, Seercull, and Starfury can fire these arrows. Additionally, the Saradomin bow and Guthix bow can fire these arrows, although the extra damage chance will be 1/10.
They also have a 1/10 chance to deal extra fire damage when fired, increasing to 1/5 if using the Zamorak bow. They will also cause Bandits to attack you. They can also be used as a Zamorak item at God Wars Dungeon to keep the followers of Zamorak from attacking you. This can be an advantage to players wishing to use other items when going for God Wars Dungeon bosses (like the Zamorak boss, K'ril Tsutharoth), so they can keep 1 Zamorak arrow in the quiver and use an armour piece of their preference instead of having to choose from the Zamorak armour pieces thus possibly giving lower stat bonuses (example: the player can change a Zamorak platebody to Bandos chestplate).
Using a Zamorak arrow in a Tirannwn Quiver will not stop followers of Zamorak from attacking in the God Wars Dungeon.
