Due to the relatively scarce and also unobtainable material for newbies getting bit by a snake almost certainly means death and not too slowly either specially when your playing a newer character.
Although it makes sense to brew an anti-venom with the venom itself it would perhaps be better if all ingredients where forageable instead so at least then people can have a fighting chance to stop themselves from dying when a snake pops out of a log...
It would also be good if the poison did not do so much damage so that you at least have a chance to administer an anti-venom at the moment its pretty well a certain death scenario.
Theres a thin line between making something too hard and too easy, snakes and the anti-venom currently are rediculous.
