Cyasma Spire

Cyasma Spire is and instance part of story quest.

Quest takes you to the top of mountain near Agnurok Engine. Meet Mysterium Chief Researcher and  there. Enter the Cyasma Spire using teleportal and talk to popori scout Kuni (hiding left of entrance) there before continuing.

Quest tells you to sneak and use side passages to avoid argons. Actually it's just easier to run (using Speed Potion or similar buffs). Avoid getting hit by the Argons and you should outrun them and have only two cubes chasing you. If possible drop aggro at end.

At the end destroy the Cyasma Coils and use teleporter before monsters get there.
