- leaping strike > crushing grip > Spawn banelings > Laviathon
I count and I'm well within 10seconds and I get no achievement. This is my last achievement for Kerrigan so its pretty frustrating. I have a save right before trying it. I've attempted many times and it never works. Doesn't matter in what order I cast them either.
What abilities did you use? Did it work for you?
Also I've been completing all levels and achievements on Brutal but i'm currently doing this on Normal - Death From Above Level. I go from start straight to the first base at the south wait for Laviathon to come up then save and attempt the achievement. Does it need a specific difficulty and what level did you try it on?
