Icethrower:
This backpack and spray nozzle looks similar to a flamethrower but shoots a 45-foot-long
cone of cold that deals 9d6 points of cold
damage to creatures and objects in the
area. A successful Reflex save (DC 17) halves the
damage. Using the icethrower is an
attack action and provokes
attacks of opportunity.
The cold fuel stored in the icethrower's backpack is drained after 10 shots but can be replenished (at the cost of the item's purchase DC).
