Shadow Burst

Shadow Burst requires a Magic level of 64 to cast and can reduce your targets' damage dealt by 5% for 10 seconds. It has a 100% chance to reduce your targets' damage when cast as an auto-attack. If this spell is used with an ability, it only has a 10% chance to reduce damage, or a 20% chance if the caster has Dark Form active. It requires two death runes and four earth runes to cast. The base damage of this spell is 614, and it scales up to 720 at 75 Magic.

When cast as an auto-attack, this spell will strike a 3x3 square area surrounding the target, hitting other players and monsters in this space. Damage to secondary targets is slightly less.^[1]

As with all Ancient Magicks spells, the quest Desert Treasure must be completed to cast this spell.
