Mission 4 - Amon's Reach | Achievements - Legacy of the Void SC II: Legacy of the Void Guide

Amon's Reach. Requires you to complete the mission on any difficulty level.
Close Call. During this mission don't let the health of warp conduit drop below 2000 points. Despite appearances, it is an easy task. All you need to do is destroy every void thrasher immediately as he appears on the map. Additionally, the warp conduit is a very resistant building that is able to survive a long assault. You must only avoid situation when two void thrashers will attack the warp conduit simultaneously, as in that case the durability of the building will drop very quickly.
Jump the Gun. Clean all launch bays before the last, fifth void thrasher appears while playing on the normal difficulty level. This enemy will appear exactly during the twenty minute of the game. It means that you have twenty minutes to complete the whole mission. Ignore the solarite, focus on creating new units and send combat groups towards the launch bays as quickly as possible. Don't attack zerg which you don't need to destroy. You can also ignore the previous void thrashers. Not all of them, as in that case you can easily lose the warp conduit, but two of the four that will appear before the twenty minute can be ignored. The time saved in that way should be used for cleaning the launch bays.
A Royal Thrashing. You must complete the mission on high difficulty level without killing the void thrashers. The hardship in obtaining this achievement lies in the fact that each thrasher shortens the time for completing the mission. While one can be survived, two are a problem, and with three the resistance of the warp conduit will fall down rapidly. Due to that, you cannot complete the mission with a large army, but you must use a trick instead. For example, use the dark templars. They are invisible, so if you manage to avoid detectors you can clear the launch bays without causing alarm among zerg. You will need a strong economy, the defense able to withstand attacks, large number of dark templars and a good coordination so that you will reach the launch bays without being noticed. Another method is creating a massive army and ignoring unimportant targets on your way to the launch bays, but this method requires time which you can run out of very quickly.
