Searing Blade (weapon)

Searing Blade is a rare world drop item; it can be dropped by mobs or found inside chests in old world zones such as Northern Stranglethorn and Hillsbrad Foothills.

In the RPG
When drawn, this sword becomes unnaturally hot to the touch - not enough to start fires, but sufficient to burn and blister unprotected skin. In moist environments, the warm metal sizzles, and in the rain or underwater, it bubbles and pops.
