After our low-agility priest almost got burned to death about three times, we decided to make up a single use, disposable fire-extinguisher for PC's to carry. I'm thinking about something half the size of a car fire extinguisher, so pretty light and compact. Maybe about the size of a large-ish frag grenade. Full round action to use one.
Now I'm happy with a price of 25 thrones for this item, but I'm a bit unsure about game mechanics for it. If I make it give a bonus to the victims agi roll to put the fire out, it is useless if the victim is unconscious or an inanimate object. Maybe a tech-use roll? Ballistics skill to hit the fire? Anyone have any suggestions for the mechanics behind this oh so usefull item?
