Posting UK Video now as well... oddly enough I purposefully tried not to shatter any frost tombs (didn't use magma/elementals, didn't use chain lightning, didn't use thunderstorm, etc), but still did not get the achievement. Not sure why. Maybe my searing totems of my DK's diseases killed a frost tomb before it died or something. Anyone know if frost resistance helps against frost tombs? I'll drop an FR totem and go slow and make sure I don't hit a tomb at all.
