Super Antipoison Potion

Once the desert was full of snakes, until they were banished below the sands by an angry goddess. Only rarely do they manage to break through the surface of the dunes to bite someone, and their venom has been concentrated so heavily by their solitude, that it's lethal to anyone that suffers it.

Fortunately, the shamans were able to create this antipoison, stronger and more powerful than previous tiers. It has saved many lives.
