While in quicksilver form, the wyrmling can't attack or fly, but gains a climb speed of 6, ignores difficult terrain, and doesn't provoke opportunity attacks. It can squeeze through any aperture a Tiny creature could fit through. The wyrmling can return to its normal form as a free action on its turn. When it returns to normal, each creature within 2 squares grants combat advantage to the wyrmling until the end of the wyrmling's next turn.

Description: THE NESTS OF MERCURY DRAGONS are found near poisonous volcanic vents and noxious sulfurous springs. These inhospitable conditions require mercury wyrmlings to travel great distances to hunt for food, instilling a desire to explore the world at an extremely young age. As a result, a mercury dragon wyrmling can often be found a great distance from its home.
A mercury dragon wyrmling's form is incredibly fluid, and its reflective appearance makes it difficult to spot in areas that have homogeneous surroundings.
