Details: 
 
In Sea Caves, must be found, cannot purchase unless sold prior (eg; sell then repurchase as a means of refill). When found has 8 (out of 20) charges (each charge is equivelant to a Flamethrower usage charge) - perhaps near waterfall or edges of Sea Cave area...

Alternate means of refill - combine Firestorm potion (if potion causes lvl4 firestorm, each should charge the Tank with +4, since Flamethrower causes lvl1 Firestorm). Max 20, unused potential is 'spilled' (eg; combine lvl4 firestorm potion with tank at +18 fills tank to only 20, unused is 'wasted').

For Engineering 40-45 possible 'backfire' of firestorm(1-5) to party when filling: 20% at 40, 16% at 41, 12% at 42, 8% at 43, 6% at 44, and 2% at 45

Level of firestorm backfire = int(1 + ('new' fill level / 5 ) ) where 'new' level is how full the tank would have been if successfully filled/charged. No risk if sold/bought back. Also if backfire, 10% chance that tank is destroyed and 5% chance that flamethrower is destroyed (odds computed as same number, so if flamethrower only can be destroyed if tank was already).
