Extinguish Fire 1 (Source)

I am getting 46 uses per blanket with an effectiveness of about 500 on each use. I tested the blankets about 50 times last night each with the same result. Much like cure poison and disease, if the effectiveness is high enough it will extinguish the patients fire with the use of only one charge from the blanket. It costs approximately 200 mind points to extinguish fire. Also, you will need to move the /extinguishfire macro from your macro pad (found under the other macros tab) to your toolbar in order to use any fire blankets that are in your inventory
