A Vengeful player is a one that, when lynched, is awarded the ability to kill any other player as they die.
Vengeful is a valid role to be used in a Normal game, but only if that role is Town-aligned.
Some versions of Vengeful are allowed to kill a player upon death regardless of whether they are lynched or killed by another means.
Use & Power
Vengeful when given to the Town can be seen as a way to redeem the faction and can act against swing. If elements of swing are not already present, the addition of a Vengeful player may have the opposite effect.
Vengeful Townies are in a unique position to solve speculated problems. If there are already a high number of Power Roles as in a Role Madness game, Vengeful can be seen as a good addition to the town.
As it is a straightforward role to play, consider adding a Gladiator instead.
It must be decided before the game begins whether a Vengeful kill will work in LyLo.
Vengeful scum roles greatly enhance swing. A lynch is the Town's weapon against scum: giving scum an extra kill essentially punishes the Town for doing what Town is expected to do. For adding dynamic gameplay that changes upon the lynch of a scum player, consider Enabler.
Claiming Vengeful Townie is not advised (unless your actual role is Vengeful and Mafia-aligned). The effect of giving its faction a bonus kill is useless unless you yourself are worth lynching - otherwise it's obviously more profitable to lynch the player you would Vengefully kill while leaving you alive. Thus, Vengeful claims under duress are seen as grounds for a policy lynch.
As a Vengeful kill is in its best case, a second chance at a lynch, a Vengeful player is already working uphill just by getting the opportunity to use their power. It's best to kill whoever would be the lynch the next day as a Vigilante would. If the Town is at Odds, consider no-killing, as the Town may go to Evens on the next day, and depending on game factors this may offer crucial information to be gained from Night Kill Analysis.
Sample Role PM
Welcome, [Player]! You are a Vengeful Townie.
- Kill: When you are lynched, you may target another player in the game to attempt to kill them.
- You win if all threats to the town are eliminated and at least one town-aligned player is alive.
A Gladiator limits the players eligible to be lynched to the Gladiator and its target.
A Vigilante is a Normally pro-Town role that can kill another player at night.
