A naabe stormbringer is a familiar which can be summoned within the Dungeoneering skill. Summoning it requires a Summoning level of 63. While summoned, this stormbringer has a passive ability that grants the player an invisible 7% boost to their magic defence.
The Snaring Wave Scroll enables the use of the Snaring Wave special ability for a naabe stormbringer. Using a naabe stormbringer pouch on a Summoning obelisk creates ten snaring wave scrolls. The special move deals a more damaging attack that is 50% more accurate, deals more damage, and immobilises the opponent.
