Soulash is an Archaic spell that is unlocked by equipping an Ethereal Staff. This spell requires a Magic level of 115 to cast and inflicts damage equal to 100% of your max hit 4 times. There is a 0.6 second delay between each of the 4 attacks for a total duration of 1.8 seconds. Each hit has a 30% chance to stun the enemy for 1 turn. This attack is avoidable.

As with all Archaic Magicks, damage modifiers from equipment, prayer, and potions will apply. Curses and damage-modifying Auroras can also be used, though special attacks will not work.
