|Rod of Malrion|
Source: More Magic of Thassilon, pg(s). 5
Presumably named after the magus who first created it, rods of Malrion originated in the Thassilonian Realm of Wrath, Bakrakhan. Made of white oak and sheathed in rune-engraved steel, each rod is approximately 14 inches long. The wood always appears to have been burnt on both ends, as if it had been collected after a forest fire.
The rod's user can create four walls of fire around a target for a minute's time and can determine whether the heat of the fire radiates on the inside or outside. The walls' tremendous heat can burn creatures who approach them, much less those that cross it.
