Flare (Flame Tounge Shortsword

Rare

Wondrous item, rare (requires attunement) This shortsword appears to be made of molten steel that seems to find its way to shape right before it strikes its target. While attuned to this sword, you feel comfortable in temperatures as low as 20 degrees below zero Fahrenheit and as high as 120 degrees above zero Fahrenheit. You can use a bonus action to speak this magic sword’s command word (‘devastation’ in Terran), causing flames to erupt from the blade. These flames shed bright light in a 40-foot radius and dim light for an additional 40 feet. While the sword is ablaze, it deals an extra 2d6 fire damage to any target it hits. The flames last until you use a bonus action to speak the command word again or until you drop or sheathe the sword. This item can be found in the Dungeon Master’s Guide
