Ethereal Knives

Ethereal Knives (often referred to as EK) is a spell that throws ten knives in front of the caster that deal physical damage. Multiple knives cannot hit the same target. The angle of the spell's arc is fixed and does not depend on where the cursor is, unlike other projectile skills.

Despite the fact that it does physical damage, Ethereal Knives is a spell and not an attack. It does not utilize weapon damage in any way.

Skill functions and interactions

• Physical spell damage: Ethereal Knives is affected by modifiers to Spell Damage, Physical Damage, and Projectile Damage. Its damage can also be improved by , , , Hatred, and Herald of Ash.

• Projectile speed: The projectiles move at an average speed of close to 120 units/s for roughly 0.25 seconds, putting their effective range at somewhere around 30ish units. Then inherently have a variation of +/−40% base speed, but the average will be around 30. Modifiers to projectile speed will increase the average distance that Ethereal Knives projectiles travel before they fade, effectively increasing the maximum range of the spell.

• Leech: Since it is a spell, Ethereal Knives is not affected by Physical Attack Damage Leeched as Life or Physical Attack Damage Leeched as Mana. However, unspecified leech such as from , and will function with Ethereal Knives.
