Mission 3 - Evil Awoken | Achievements - Whispers of Oblivion SC II: Legacy of the Void Guide

Evil Awoken. Requires you to complete the mission on any difficulty level.

Blade of Skahuras. Kill 20 units using Zeratul's shadow strike ability. A very easy task, which can be completed easily at the start of the mission, in front of the void catalyst, or during the escape if you get rid of stalkers and will be escaping only as Zeratul. During the mission you will have many occasions to use the shadow strike, so a lack of targets will not be the problem. Many of opponents will be standing in groups, calmly waiting for you to eliminate them one after another. You must only remember that the ability needs few seconds of break before you can use it again. Due to that, give Zeratul a moment to rest after each battle.

One With The Shadows. When playing on normal difficulty level, none of your units can die before destroying the void catalyst. A troublesome achievement, since during the mission you will face many hard opponents, including hybrids. Due to that, you must take breaks regularly, allowing your units to regenerate the shields to maximum. Use Zeratul's abilities and always focus your fire on the most dangerous opponents. Move and fight carefully, don't waste your units, complete the side objective and save the game regularly.
