I like how a topic about invading hell turns out to become a topic debating the efficiency of embarks :p
In comparison "garden vegetables" like cranberries, grapes etc. cost 2 units per plant, but come in bags rather than barrels. So it's a much simpler formula for those:
5 plants = 10 points for 1 stack of 5 plants + 3 points for barrel/pot = 25 units of alcohol for 13 points = 0.52 points per unit of booze
Now, that's very cheap !
Never thought to math the brewing of vegetables. I guess because I have never really messed up with them before... Vegetables are too, you know... elven, for me...
On the flip side, with PH, you get seeds, wich I think you
can cook, but not on their own. Seeds need to have a solid food to be cooked with.
Vegetables seems to be the way to go anyhow.
And for the metal weapons, I'm pretty sure that Diamond will get attacked very very quickly. So, there is no point/time to take metals, and dig for magma.
Also the very point of the run is to
die in a horrible way escape hell. Thus, reaching magma pretty much means that the challenge would be completed.
For the weaponry, I would'nt bother with armor because metal is not viable in terms of price, and leather is just not good enough.
You can get wooden spears for 9, copper warhammers for 18 (these could kill "easily" inorganic deamons if one dwarf manages to hit).
Also, with the new mechanics of morale, dwarves will probably never attack deamons, and flee from them unless they have good discipline, to get to proficient, it costs another 45points per dwarf -.-'
Being a coward is a lot cheaper...
