Shadow Blitz requires a Magic level of 76 and can do a maximum of 24 damage per hit. It can lower a target's Attack level by 15%. This spell's effect does not stack to lower the target's Attack level to zero.
When used against the Abyssal Sire, Shadow Blitz has a 75% chance of disorienting it for the first phase of the fight.
As with all Ancient Magicks, Desert Treasure is required to cast this spell.
Remember, you cannot use Lunar spells, Standard spells, or Arceuus spells if you are using Ancient Magicks.
