Ethereal Knives skill screenshot.jpg

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.
