Flames on Command

Flames on Command: Upon command, the weapon will be sheathed in fire. The fire does not harm the wielder. The effect remains until the command is given again, or until the weapon is dropped or sheathed. While it flames, all damage done by the weapon is treated as fire damage, and an additional +1 bonus (in addition to the weapon's normal bonus) is added to damage when fighting trolls, treant, and other creatures especially vulnerable to fire. It casts light and burns just as if it were a torch.
