Wand of fire

This wand will produce a fiery ray which extends for 6 squares, and inflicts 4d6 fire damage on any creature struck. The ray will bounce off walls, doors, and/or any creature with Reflective. The ray can affect certain types of map squares: forest squares will be set afire, ice squares will be melted, and water or acid squares will be boiled dry (leaving behind pits and steam or acid mist).
