Shadow Rush requires a Magic level of 52 and can do a maximum of 14 damage (without any magic damage boosts) per cast.

As with all Shadow spells, it can lower your target's Attack level. Shadow Rush has the ability to lower your target's Attack by 10%. The effect of all Shadow spells does not stack to lower the target's Attack level to zero.

When used against the Abyssal Sire, Shadow Rush has a 25% chance of disorienting it for the first phase of the fight.

As with all Ancient Magicks spells, the Desert Treasure quest is required to cast this spell.
