Introduction to Assassins and Poison Damage in DD 5E

Dungeons Dragons 5th Edition (DD 5E) introduces a unique set of challenges and mechanics for players and DMs alike. Among these, the Assassin class, or NPC, is particularly intriguing due to its deadly poison damage capabilities. Poision damage is a potent gameplay mechanic, but its application and effects, especially in the context of the Assassinate feature, can sometimes be confusing. In this article, we explore the exact mechanics of poison damage when dealing with Assassins, clarifying any misconceptions regarding its persistence and usage.

Poison Damage in Assassins: A One-Time Effect

In Dungeons Dragons 5E, the poison damage dealt by Assassins when they trigger the Assassinate feature is a one-time effect and does not linger on their weapons or remain in subsequent attacks throughout the same combat. The Assassinate feature allows Assassins to add an additional 21-24 poison damage to their first successful attack against a surprised creature (7d6 poison damage) on top of the weapon's normal damage. However, this poison damage is not carried over to any subsequent attacks unless the Assassin applies poison to their weapon using a separate method, such as a poison item or spell.

How the Assassinate Feature Works

The Assassinate feature, when used, requires an Assassin to fulfill a specific condition: attacking a surprised creature on their first turn during combat. When this feature is activated, the Assassin scores a critical hit on their first attack against a surprised target. Additionally, the assassin deals an extra 7d6 poison damage on a successful hit, on top of the weapon's normal damage. This damage is a one-time application and does not carry over to subsequent attacks unless the Assassin applies poison again to their weapon.

Understanding the Shortsword Attack

When an Assassin makes an attack with their Shortswords, the weapon itself carries a melee weapon attack description. The Assassinate feature, however, is a separate ability that triggers during the first round of combat against a surprised target. The Shortswords' melee weapon attack is as follows:

Melee Weapon Attack: To hit, roll a d20 and add 6. Target: one creature within 5 feet. Hit: 6 (1d6 3) piercing damage, and the target must make a DC 15 Constitution saving throw. On a failed save, the target takes 21 to 24 (7d6) poison damage. On a successful save, the target takes half as much damage.

This attack does not incorporate the Assassinate feature unless the target is surprised and the Assassin triggers the feature. The Assassinate feature is an additional effect that can only be applied once per combat round, not a persistent poison effect.

Conclusion: Ensuring Clear Game Mechanics

Given the clarity of the mechanics in Dungeons Dragons 5E, it is crucial for both DMs and players to understand that the poison damage from the Assassinate feature is a one-time application and not a lingering effect. The Assassin must reapply poison to their weapon for it to be used again in the same combat. This understanding ensures fair and consistent gameplay, enhancing the immersive and tactical experience of playing as an Assassin in DD 5E.
