Alchemist Fire, Acid and other gunk

[stranger38]

Greetins my fellow players

I was reading the felltower campaign another day (great stuff by the way)

and while fighting a monster, they`ve dropped a jar of alchemist fire and everyone was worried it would break and turn the cave into a firepit.

Now, here is my question:

a pint of the stuff does 1d. more pints do more damage? so 10 pints do 10d damage?

Liquids tend to spread out rather readily, so 10 pints should just cover around 10x as much surface as 1 pint. If 1 pint covers 1 hex of ground, 10 pints would cover 10 (roughly speaking, you'll be looking at one hex, all hexes adjacent to it, then another three hexes on the periphery). There's justification for a target who is in the middle to take more damage, as in addition to standing in open flame they're also surrounded on all sides by it, but I probably wouldn't do more than +1 in this case (if you had some sort of extra-hot accelerant burning, dealing 2d burn or more, I'd be inclined to have such a character suffer a further +1 per die instead).

For acid, things are similar, although you don't need to worry about inflicting more damage to someone in the middle (and note it's probably only damaging their boots, at least at first, unless it spills on them directly).

Damage from fire depends on the temperature and contact area(like throwing a molotov at something (1d6 with alchemist fire, but 3d with molotov) is more damaging than running through the same molotov flames on the ground (1d-1). Same with acid, strong acid - more damage, spraying acid from a bottle (1d-3) is less damaging than fully submerging (1d6-1 or more).
