Delicate Instruments

Kill 8 Kobold Geomancers in Jasperlode Mine, then return to Hamish Bergwort in the Tower of Azora.

Blast it! Every time I try to calibrate these sensitive arcane instruments, they get thrown off again by a surge of energy. The surges seem to be coming from the north, where those primitive Kobolds have been practicing their crude magic. Could you clear some of them out, so I can continue my work?
