Smouldering tansymum is formed when lighting tansymum with the right hand weapon slot empty. It is automatically equipped. If dropped or unequipped, it turns into ashes and the message "The smouldering tansymum disintegrates to ashes." is shown. If the right hand slot is full a message "You need to have your right hand free to keep the tansymum burning." appears. Smouldering tansymum be used to lure wimpy birds to capture them with a bird snare. However, it also causes diseased kebbits to attack. Tansymum, as well as Lavender and Fever grass, cannot be lit outside of Oo'glog.
