Unfathomable Darkness is a medium armor set. When you deal damage, you have a 10% chance to call a murder of crows around you for 12 seconds. Every 3 seconds a crow will be sent to peck the closest enemy within 12 meters of you, dealing 4000 Physical Damage. This effect can occur once every 15 seconds.
Unfathomable Darkness is part of the Clockwork City DLC and drops in Clockwork City in the Overland content. You can also find it on Guild Traders. Each set item is bound on equip. You can acquire medium armor, jewelry and weapons for this set in the Ebonshadow motif style.
Magicka Nightblades have one of the best sustained setups due to their cheap spammable skill Funnel Health/Swallow Soul. Nightblades also have great ultimate generation due to Soul Harvest and the Catalyst passive, which is especially great in trashfights as they can dish out Ultimates twice as fast as other classes. With sets like Master Architect they also shine, activating Soul Harvest and Architect results in a 35% damage boost.
