Description: SKILLED SCOUTS, EMISSARIES, AND ASSASSINS, mercury dragons are capable of shapechanging tricks that other dragons can’t match. The breath of a mercury dragon poisons the body and the mind, rendering its victims unable to see the mercury dragon escape or circle around for a killing blow. A mercury dragon craves variety and new experiences.
