Blade of Eternal Darkness

The Blade of Eternal Darkness has no specific class restriction, but it is aimed more towards spellcasting classes. If a character wields this dagger and casts a damaging spell on an enemy, there is a chance that the dagger will deal 91 Shadow damage to the target as well as restoring 91 mana to the wielder.

This item drops from Princess Theradras, final boss of Maraudon.

Ability such as Shadowform and Curse of the Elements, which increase overall Shadow damage, will also increase the damage done by the proc. The damage can also crit but has its own rate. The mana regenerated cannot be increased.

Non-Channeling AoE damage spells like Shadowfury can cause more than one proc at the same time (can proc once per each enemy hit), resulting in more damage done and mana returned by proc.

The effect is named Engulfing Shadows.

The blade's drop rate is estimated at 0.1%.

The dagger was changed in Patch 1.10.0. Previously, the proc was an "On Use" ability with a 1.5 second casts and a 30 second cooldown.
