A Broodoo shield is a special member's only shield. It can be created with 35 Crafting by using a hammer with a tribal mask with two snakeskins and eight nails in your inventory, granting 100 Crafting experience. The colour of the mask from which it was made determines the colour of the shield. All broodoo shields requires 25 Defence to wear.

The animation when the passive effect occurs.

Broodoo shields have a unique passive effect when used in combat, similar to the black mask; it has a 10% chance of draining an opponent's combat stat by 1, and then 5% of their remaining total. The enemy must be in close range, it must still have over half of its hitpoints and its skills must be at the base levels for them to be affected. There are 3 types of broodoo shields:

The number following the name of the Broodoo shield represents the number of charges left on the shield, starting at 10. Every time the passive effect is used, this amount will decrease by one. There is no way to recharge the shield after the charges have been depleted, but it does not affect the shield or its stats once they are all used.
