Poison Basics in D&D 5e
In Dungeons & Dragons 5th Edition, a poison represents a toxic substance that can impair or kill when ingested, inhaled, absorbed, or injected. This guide explains how poisons work in the rules, the typical forms they take, how creatures can be affected, and how to incorporate them meaningfully into gameplay. Poison is a mechanism for risk, exploration, and tactical choice rather than a constant threat, and its impact depends on exposure, resistance, and the availability of remedies.
Official Rules for Poisons
Poison Traits and Mechanics
On the SRD and in the Player’s Handbook, poisons are described with game statistics such as name, type, price, rarity, and effects. A poison typically requires an action to apply and delivery methods include contact, ingestion, inhalation, or injection. When a target is subjected to a poison, they usually make a saving throw to avoid or mitigate the effect. The specific effect—poisoned condition, hit point damage, or another penalty—is defined by the entry. Poisons generally target a single creature or small area and are not weapons, though they can be applied to weapon attacks.
Saving Throws and Conditions
Poison effects commonly force a Constitution saving throw. On a failed save, a creature suffers the stated consequence, which might be the poisoned condition, exhaustion levels, or hit point damage. On a successful save, the effect may be halved or negated depending on the poison’s design. Some poisons have a cumulative effect or ongoing damage over time, which can escalate danger if multiple doses are delivered or if the initial effect is not properly treated.
Types of Poisons and Examples
Poisons in D&D 5e come in many forms, from simple hunter’s poison to elaborate alchemical concoctions. Below is a summary of common entries including type, source, typical effect, and availability. This is not an exhaustive list, but it reflects canonical material and widely used references from official releases.
Common Poison Types Overview
| Poison Name | Type | Effect | Typical Rarity |
|---|---|---|---|
| Basic Poison | Simple toxin | Poisoned condition or minor damage | Common |
| Black Adder | Venomous | Constitution save or take poison damage | Uncommon |
| Drow Poison | Arcane/alchemical | Poisoned condition plus additional penalties | Rare |
| Wyvern Poison | Monster-derived | Significant damage and poisoned condition | Rare |
| Assassin’s Poison | Custom high-tier | Heavy damage or incapacitation | Very Rare |
How to Apply and Use Poisons
Applying poison usually takes an action and may require a tool kit or special materials. Archers and melee weapon users can coat blades, while alchemists might craft specialized delivery items. In narrative play, poison can be introduced through contaminated food, tainted water, or creature attacks. DMs should clarify whether a trap or stealth encounter includes poison, and how much exposure is needed to trigger effects. Tracking doses and methods of delivery can add tension and encourage creative problem-solving.
Delivery Methods and Practical Use
- Coated Weapons: Contact poison applied to a blade or arrow.
- Cont consumables: Poison added to food or drink.
- Creature Attacks: Monster abilities that inject or spray venom.
- Traps: Poison darts, vials, or gases triggered by mechanisms.
Detecting and Countering Poisons
Detecting poison often relies on skills such as Investigation, Perception, or Medicine. A passive Wisdom (Perception) check might reveal suspicious traces, while a successful DC Investigation check can uncover hidden poison components. Spells like Detect Poison and Purify Food and Drink provide reliable ways to identify or neutralize poison. Creatures with truesight or heightened senses may notice alchemical signs automatically, and certain class features, such as the Rogue’s Uncanny Dodge, can mitigate damage once exposure is identified.
Detection and Countermeasures Summary
| Method | What It Does | Limitations |
|---|---|---|
| Passive Perception | Notice obvious signs of poison | May miss subtle or concealed poison |
| Investigation Check | Find hidden poison sources | Requires time and ability check |
| Detect Poison Spell | Magically senses poison | Concentration, range, and duration limits |
| Purify Food and Drink | Removes poison from consumables | Does not cure poisoned conditions on creatures |
Design and Campaign Considerations
When using poison in a campaign, consider the fiction as much as the mechanics. Ask who benefits, why the poison exists, and what risks are involved. Poisons can be tools for intrigue, survival, or moral dilemmas. Encourage player agency by offering multiple ways to handle threats: stealth, detection, magical defense, or negotiation. Balance is key; powerful poisons should be rare, while weaker variants remain accessible to low-level parties. DMs should also account for how different environments, cultures, and factions might use or regulate poison, creating richer, more coherent settings.
FAQ
Reader questions
Can You Stack Poison Effects?
Typically, only one source of the poisoned condition can apply at a time, though multiple damage-based poison effects may accumulate if the DM allows. Refer to specific rules or monster abilities for stacking behavior.
Are There Resistances or Immunities?
Some creatures, such as constructs and certain oozes, are immune to poison damage or the poisoned condition. Creatures with particular traits, like poison immunity, automatically succeed on saving throws against poison effects. Otherwise, resistance or vulnerability depends on the poison type and creature nature.
How Do Long-Term Effects Work?
Ongoing damage or cumulative penalties from poison can be managed through short or long rests, specific magic, or timely use of antitoxin and similar remedies. Tracking durations and clear communication help avoid confusion at the table.
