is there any other way to make poison besides w/ a snake? a combination of widely known and available plants mayb? boiling certain mold or such? anything else?

catchin a poisonous snake in the wild(God forbid I would ever need to use a skill such as this) w/o a handgun(using snake ammo)  could be a dangerous situation.

anything on whether cooking the animal would be suffcient enough to kill all the poison and eat it? even if the cooked animal is basically cooked till CHAR black?

This is a very interesting question.

I think it mostly depends on the objectives of the two parties. If the terrain was open and clear and the only objectives of the two parties is to survive then I don't think anyone would lose.

yeah it's all fun and games till someone gets an eye poked out.
definitely eye protection at the very least.

my glorious mock battle memory involves blowguns, we were using modeling clay in .40 caliber aluminum tubes about 2 feet long, pegged a friend in the neck from about 25 yards in the  dark.
he was sillouetted and i remember aiming about 2 feet above his head, pufffft! and about a quarter second later he let out some expletives, it left a little semi-bruise that lasted a day or two.
great fun.

slings seem like they'd favor the trick of darting out of cover and firing on your way to more cover.
more like shooting skeet than riflery...  archery can be like skeet but it's a lot closer to riflery than slinging is for sure.
well good luck guys, i hope it happens.

Hmmm a cut or a bruise I dont know wich I choose

or if the bruise causes a blood clot wich clogs a artery causing a heart attact

the tennis ball does kind of restrict the arrows distance butt  i can still get my bow to shoot about 100 yards with the quarter of a tennis ball on there

Its like shooting flu-flus though,  at 25 -30yds my squirrel arrows don't really have any thing on them, but my regular arrows now thats a different story.  Accuracy comes from the arrow tuned to the bow, not on the bow alone, actually the arrows are more important.    And this question I assume was intented to see wich one we thought would be more useful in battle.  I guarantee that I can get better accuracy and grouping with my arrows at 100 yds without having tennis balls glued to the end of them.   Now the other suggestion was to give the sling weighted (caulk filled) balls to throw.  That would give an advantage for the sling because all of the ammo is the same size and weight, and a sphere shaped that was meant to be thrown.
