"Proficient in the study of Medicine, an invisible killer allowing him to be skilled in Poison."
Urasil is one of the free-to-play heroes in Archero and can be unlocked starting from Chapter 3. His enhanced Poison effect stacks with any other Poison ability.
He is a deadly assassin that deals additional damage over time (DoT) in addition to his regular damage. Like basic Poison, the Venom effect is permanent and does not expire after a set amount of time (unlike the Blaze effect), so damage can still be caused while the player focuses on dodging. His upgrade stats are nearly pure offensive in nature, able to eke out a bit more damage while giving two of these stats to other heroes when unlocked.
