A Most Violent Loa

Thanks to this Thread and for the patch today I was able to get this achievement.

PLEASE NOTE! If you are currently on a Prey Hunt after the 3rd emote Filo won't appear! Finish the hunt them come back as your progress is tracked.

You have to go to the Kapara pool where NPC Feevra lives (32.32, 22.39). (EDIT: Apparently any of the Kapara in the Zone will count towards this achieve - Thanks to Jerrodan and others for this info!)

There, you have to kill the Kapara and Kapara pups. You'll have to let them respawn over and over. You know you're on the right track as you kill them once you get the following dialog:
1. Your actions have caused an eye once closed to open...
2. The eye that watches you now glares...
3. Rage and darkness swell behind the glare which fixates on you...
After that line, kill Kapara until you get the achievement. Once you get it, Filo will spawn and try to kill you. You don't have to die to get this.

Thanks to Varundrit - it takes about 25 Kapara kills in the zone for each emote to appear and then 25 more for Filo to appear after the 3rd emote. Total around 100 Kapara and Kapara Pups to kill for this.

Leaving the zone or logging doesn't appear to reset this progress!

First the poor lobster Rare in Eversong who was just concerned about his little sunflower and now i have to commit Kapara massmurder? We truely are the bad guys, aren't we?

All the Kaparas in the zone. Make sure to give them a swift and peaceful death. Also be aware of [spell=1292164]/[spell=1264314], not sure how it triggered but a normal kapara turned big and 2 shot me.
