Pearl bolts (e)

Enchanted pearl bolts are iron bolts tipped with enchanted Pearl bolt tips made from Oyster pearls. Pearl bolts can be enchanted into enchanted pearl bolts through the spell Enchant Crossbow Bolt (Pearl) by a player with 24 Magic. The spell enchants 10 pearl bolts at a time and requires 1 Cosmic rune and 2 Water runes to be cast.

Enchanted pearl bolts are enchanted with the Sea curse enchantment. This gives the bolts a chance of striking the opponent with a mighty bolt of water, dealing 7.5% extra damage. This ability is negated by opponents wielding water staves. However, it will have more damage and higher accuracy, on fiery monsters (i.e. Tzhaar).

This effect can be triggered with auto attacks and abilities, with abilities consuming one bolt per activation.

The chance of the special attack occurring is increased upon the completion of the Elite Seers' Tasks.

The effects of these bolts seem to be the opposite of enchanted dragonstone bolts.

Trivia

 * On 23 February 2010, a bug was leaked in which one could duplicate enchanted bolts but was patched on the same day. Many players were banned for using this glitch.
 * These bolts were untradeable when released, but a hidden update in 2007 made them tradeable.
