Malefic Viper's Poison (Rare)

Jake received this skill in chapter 21 as part of his profession.

[Malefic Viper’s Poison (Rare)] – The Malefic Viper stalks its prey and needs only to strike once as venom devours its prey. Increases the potency of all crafted poisons. Grants the ability to craft a poison with a rarity above that of your Concoct Poison skill if certain conditions are met. The poison may at most be upgraded to the rarity of the Malefic Viper’s Poison skill (Common --> Rare). Allows poison not to lose efficiency for a short amount of time after being applied to a weapon.
