Saradomin arrows, released 4 August 2010, are a possible clue scroll reward from any level clue scroll. After being shot, they will disappear, meaning that they cannot be retrieved with one of Ava's device. (This is useful if you don't want to use the Ava's device, since you won't be tempted to pick up arrows, although wearing the accumulator [or alerter] will still give its +1.8%[+2.2%] ranged Crit.) They can only be fired from a magic shieldbow, dark bow, seercull, Guthix bow, Zamorak bow, or Saradomin bow.
They have a 1/10 chance to deal extra water damage when fired, increasing to 1/5 if using the Saradomin bow. As a Saradomin item they will keep the followers from attacking you at God Wars Dungeon and will cause bandits to attack you at the Bandit Camp.
Using a Saradomin arrow in a Tirannwn quiver will not stop followers of Saradomin from attacking in the God Wars Dungeon.
