Psionic Assault, part 2 | Challenges SC II: WoL Guide

Last update: 11 May 2016

Round 13

Enemies: 4 Stalkers

You begin the march for gold from a fight with four Stalkers. Treat them just like most enemies in this challenge, that is blocking with force fields and finishing with a Psi Storm or two. You will probably need to finish off the barely alive machines with your Sentinels. If you feel a need, you can create a Colossus beforehand, which will relieve you a bit.

Number of victims: 154

Round 14

Enemies: 10 Reapers, 2 Ghosts

Repeat the bait manoeuvre. Provoke the Reapers to attack a hologram and treat them with a Psi Storm. The pair of Ghosts can pose a threat, you could hurt them with a Psi Storm first or send in a hallucinating decoy before attacking with Sentries.

Number of victims: 166

Round 15

Enemies: 6 Mutalisks

The first such serious air attack. Place Sentries or a hologram in the front and activate the Guardian Shield to reduce ranged damage. You can call in a High Templar for help and/or move back the hurt units.

Number of victims: 172

Round 16

Enemies: 2 Vikings, 2 Marauders, 10 Marines

Definitely the hardest round in the whole challenge. You probably won't make it without any losses during the first try, though luck has much to say here as well.

Place the units like in the screen. You can't be too close to the south part of the hill, as the incoming Viking will unveil the terrain to the infantry, which will begin attacking. It's best to stay in the middle and form a ground hallucination. The Vikings will approach it and switch to ground mode to attack it. Send in the Sentries then.

Beforehand you should however stop the enemy ground units (screen), casting two or so Storms onto the blocked Marines and Marauders. As you see, everything requires proper synchronization and the difficulty is quite high because of it. On the other hand, no one said you have to reach hold with everyone on the team.

Number of victims: 186

Round 17, 18 and 19

Enemies: 20 Zerglings (17)

Enemies: 6 Roaches (18)

Enemies: Ultralisk (19)

Three consecutive rounds, which will bring you closer to the desired trophy. The challenge will take you to the north-west flank, where Zergs will try to break through the large rock blocking the path.

At first the Zerglings will attack, with which you will deal by placing two Sentry groups on the sides of the rock. Once Roaches appear on the horizon, retreat the Sentries and switch to Templars. Kill (or damage as much as you can) the enemy units, without saving up Storms and start morphing into Archons before the Ultralisk arrives. High Templars won't be needed to get the gold anymore and will be far more useful in this might form. You can morph every single one of them, or leave one or two if you want.

The Ultralisk will probably break through the barrier quickly, but you should already have an answer to that, in form of Psi units.

Number of victims: 206; 212; 213

Round 20

Enemies: 10 Banelings

Back to the past. Stop the Banelings with a force field and attack them with Sentries and whatever other ranged units you have under your sleeve. If you have any Templars left, you know what to use them for.

Number of victims: 223

Round 21

Enemies: 2 Siege Tanks

It's probably a reward for dealing with the Reapers and Vikings, as you can just send Sentries to the salient part of the platform and wait for the tanks to appear. The fight won't end there, as more groups of enemies will start appearing, but it won't be very demanding, rather just meant for fun.

Number of victims: 225 (gold)
