Pestilent Mercury


Highly dangerous sorcery employed by Dragon School spooks. Only taught to trusted members.

Releases mercury that eats away at HP. Beware, as the caster is not immune to its effect.

A body caught in the silent mercury cloud lies still, while the face twists in a tortured scream. The names of these learned sorcerers became feared for this gruesome spectacle.


Creates a pool of mercury that deals Magic damage to any enemy within it. The player is not immune to this damage.
