After the quick patch that facepunch release, flame no longer damages hatch or stone. Will post updated stats when the flamethrower is all balanced and stable.
+Tyler Lowe its quite cheap if you consider that you can easily break threw some walls with that. A normal solo or duo base would have 3 walls. now consider you need 100Fuel for the Flamethrower and 140 for each wall. You would just need 520 Low Grade Fuel. If the lootroom has extra protection i would think of upto 800 Low Grade Fuel. If you consider for the same you would need 6 - 10 C4 thats actually a very cheap raiding methode. I think it will destroy the gameplay a bit. For example in an online rade its not that strong because the owner can throw water on it. But i think you cant place barrels in an building so in an actuall rade it would be quite useless. It is just so fucking cheap to get in an base. Even a noob just with a flamethrower and some low grade fuel, which is easily harvested just by walking around and killing animals, can destroy a big base solo while they are offline.
