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 present in their inventory.
Enchanted pearl bolts have a chance of triggering the Sea Curse effect. This will cause a mighty bolt of water to hit the opponent. This ability is negated by opponents wielding water staves, but increased by opponents wearing fire staves or fiery monsters. The effects of these bolts seem to be the opposite of enchanted dragonstone bolts.
Against fiery monsters, the Sea Curse effect affects damage only, adding 1/15 of the player's Ranged stat to fiery monsters, and 1/20 against other targets; ranged boosts are taken into account as well. The fiery monsters affected are:
- All adult chromatic dragons, including the King Black Dragon, Brutal Green Dragon, and Lava Dragon.
- All metal dragons.
- Fire giants
- Fire elemental
If the player has completed the Hard Kandarin Diary, there is a 10% increase of the likelihood that the special effect of an enchanted bolt will occur. This effect is always active regardless if the headgear is equipped.
