Rogue:
Viper
Though the effectiveness of a hidden blade is often praised, the most effective weapon in the hands of a assassin is a touch of Poison. A wound from a dagger can sewn close, but by the time one feels the presence of a poison, it is already too late.
Vipers hide in plain sight, giving their enemies a lethal taste of their venom. By the time an enemy realizes what has happened, a viper is nowhere to be found.

Viper venom
Starting at 3rd level, you can inject venom through your weapons. When you hit a creature with a weapon attack, you can expend a hit die to deal additional damage equal to 1d8 + your rogue level. The damage type is acid, necrotic,
or poison (your choice).
Vengeful dodge
Starting at 9th level, you learn to lash out at your enemies when they assault you. When you use uncanny dodge, you can make a weapon attack against the attacker as part of the same reaction.
Unseen predator
Starting at 13th level, you learn to hide in plain sight, awaiting your prey. When you take the hide action, you become invisible until the end of your next turn. You can use this feature a number of times equal to your dexterity modifier, and regain expended uses on a short or long rest.
Hassassin
Starting at 17th level, your blood has become one with the venom. You gain immunity to acid, poison, and necrotic damage. In addition, you regain all your hit die when you finish a long rest.
