Starcraft II: Legacy of the Void (Mastery Achievement "Purity of Purpose")

Pardon the loud music

[@Rubeolda]

This is one of the lamest SC2 missions. Basically you are given 2 allies who can't even defend themselves and you need to babysit them because even the first incoming forces will slaughter them.

It's pretty depressing that the mighty firstborn are absolutely guaranteed to fall to the very first goddamn attack that Amon sends if you don't bail them out

[@snugz3272]

Thanks bud, your video helped me finally beat this damn mission

[@TheStarcraftJACKAL]

For gameplay purposes, maybe - but in reality they should've let Artanis handle the defenses. He got all the cool toys: DTs, Corsairs, Time Stop...

+MJk Slasher Artanis could have handled all the missions

So I was struggling to get this achievement and you won't believe how I finally did it. Nukes. I shit you not. I let my allies bases fall. I built up a few planetary fortresses and parked a handful of SCVs near each one for repairs. Then I spammed those special ops buildings that let you make nukes. I made half a dozen spectres at each side of my base, and loaded the fuck up with nukes. When the enemies came to my planetary fortresses, it didn't matter that they were so bunched up; by firing off a nuke pre-emptively so it lands when the first wave of enemies arrive, and then firing off repeated nukes on those locations every 5 seconds thereafter, it turned the ground outside my base into a massive nuclear killing ground. It was satisfying. You can, this way, spend most of your budget on nukes. Of course, don't forget to put siege tanks behind your PFs too.

+Will Davis I'm going to try this, not because I think it'll work but because it sounds hella fun

[@pat777b]

I used this strategy for this achievement. It made it fairly easy. I even ran out of kerrigan kills for the last thrasher and used banshees to kill it. This made me think about optimizing this strat to use banshees to kill a few thrashers without the laser so Kerrigan can kill a few more other stuff. Nonetheless, it seems like it's this achievement is reasonably doable without this optimization.

+Patrick Tam glad it helped you

[@ejhockey]

Nice strat using Banshees. This helped me get the achievement. Thanks.

[@dantrewartha899]

+ejhockey yeah for sure. I was just sticking to tanks, but it wasn't really working out. I'll try this, thanks for the upload

[@mmoff3]

Thanks for vid, had absolutely no success with bunkers and tanks but I got achievement with a single reload after watching this

[@wsuhgaming4613]

just got purity of purpose on brutal simultaneously. took about 100x saving and loading though but proves it can be done

[@unkmigvel]

Hey bro, did you manage to achieve the mastery achievement in "the host" mission? Please upload the video if you did

[@fuwa07]

+Miguel Morales yes, it took a few tries, just go mass dts and stalker, it important to use the stun ability from the core, For the last two void crystals you need to split your army in two.

[@unkmigvel]

+fuwa07 Thanks man, I just axcomplished it a few moments ago, I went void rays and zealots with the freezing ability :D. But for this mission I did the same strategy, it was awesome really, thanks
