Voidshriekers are voidcallers found in Netherstorm [[:File:|[, ]]]. They can be difficult to defeat by some caster classes, as they will become resistant to the first type of magic used against them. An easy way around this is to first use a spell type that you don't normally use. For instance, a shadowpriest will want to cast a holy spell first on the voidshrieker, so they won't reduce the damage of their shadow spells.
