Aftermath ArachnicideAftermath Cobweb Cleaner

You will get Aftermath Arachnicide achevement for simply killing the Spider Queen one time.  Once you do, the Aftermath Cobweb Cleaner achievement will unlock.  To get that, you must kill 5 cacoons.  Throughout the fight, players get wrapped up into cacoons.  Get the finishing blow on 5 of these (doesn’t have to be during 1 event) and you’ll get the achievement.

 

Aftermath Vermicide and Aftermath Shock Wave Jumper

Toxic Wurm Queen Location Aftermath Shock Wave Jumper

You will get Aftermath Vermicide achievement for simply killing the Toxic Wurm Queen one time.  Once you do, the Aftermath Shock Wave Jumper achievement will unlock.  To get that, you must jump over 5 shock-waves as seen below.  Throughout the fight, the Toxic Wurm Queen will spit out shock waves on the floor.  Jump over the tip of the shock-wave to get credit for jumping over one.  I found that the best way to do this is to engage the boss and just stand there shooting something long distance, jumping over them until more people show up.  You can either camp the spawn to do this and get it guaranteed quickly, or try your look while following the zerg.  Try to group up to raise the chances of it shooting at where you are standing.  Jump over them 5 times and you’ll get the achievement.

 

Aftermath Toxic Counteragent and Aftermath Detoxifier
