rift quest:Remnants of the Aelfwar  

This information is from the Public Test Shard, and may change prior to going live.
To complete this objective, simply go to the spawn points for the Aelfwar Seekers as shown on your map. Stand in the area for about 2-3 seconds and anywhere from 1-3 Aelfwar Seekers will spawn. They are relatively low health and can be readily killed. Once killed, use your Electrstatic Vaporizer while targeting the corpse to obtain quest credit.
