Miasmic Barrage (historical)

Miasmic Spells, along with PvP Worlds and the accompanying Zuriel's staff required to cast them, were released by Jagex on 15 October, 2008.

Miasmic Barrage requires a Magic level of 97 and can do a maximum of 352 damage (without boosts except for the necessary staff), or 3168 damage if cast on 9 opponents in the same time, making it the strongest spell in the game. In addition, any players affected by the spell will have their melee or ranged attack speeds reduced by 50% (weapon attack speed cut in half) for 48 seconds. It can hit multiple targets in a 3x3 square area. As with all Ancient Magicks spells, the quest Desert Treasure must be completed to cast this spell. The spell also requires Zuriel's staff to cast, making it one of the first Ancient Magicks to require more than just runes (along with the other Miasmic spells). It also has the highest level requirement of any spell.

Under perfect conditions, Miasmic Barrage can hit a maximum of 425 damage (not including a castle wars brace), using Extreme magic or Overload potions, or 3825 damage if cast on 9 opponents at the same time. With a Castle Wars bracelet, this spell can hit a maximum of 496 damage, or 3967 (on two flag holders and 7 other opponents in an uncommon or an arranged situation). Due to the high accuracy of magic, this could be one of the most effective ways of fighting warriors.

Although the damage and special effects make it excellent for battling armies of warriors, the extremely high cost and the high level requirement (meaning that mages using this spell would easily be disabled by a couple of specials from the Seercull bow, the Dragon hatchet, or even the dragon pickaxe) are major drawbacks.

Miasmic barrage costs coins to cast.
