The poisoner

by rodmlgkiller

With The poisoner installed, players craft ten kinds of poison from ampules filled by extracting essences, and each poison can be injected into an entity or added to a consumable.

What it does

Poisons are made by extracting essences and crafting them into ampules. Each poison has five tiers. Injecting an entity starts an effect whose duration grows with the tier, and each tier pushes the entity toward the next one. Tier five effects are strong enough to bring a player close to incapacitation, though poison by itself cannot kill. Milk buckets remove tier one effects unless the server changes that. A totem activates the player's effect instead of removing it, reducing the tier by one and halving its duration, and this can only happen once per minute.

The mod adds a poisoner origin built around use, working with the Origins mod, which is an optional dependency for Forge. Players drag an ampule onto an item in the inventory and press right click to poison it, and an item can carry several poisons of the same or different types. A description line showing the poison is configurable and visible by default for players with the poisoner origin. Some items can be restricted to players with the hyperfocus effect, and the origin can be toggled for everyone. Golden apples remove tier one effects, and enchanted golden apples recover tier five.

The Paralyzing poison slows the player and, at higher tiers, blocks random WASD and space bar inputs, and at the highest tier it can randomly block camera movement. The Anticoagulant poison deals damage whenever the player takes certain actions. Early on, those actions lengthen its duration, and at tier five bleeding rises with the effect duration, up to 99 percent over three minutes. The Wither poison is listed among the ten types.

Key features

  1. Ten poison types

    Poisons are crafted from ampules filled with extracted essences, with ten different types.

  2. Five-tier effects

    Each poison escalates through five tiers, and an entity advances to the next tier once the current effect's timer runs out.

  3. Totem and milk interaction

    A totem reduces the tier and halves the duration once per minute, and milk buckets clear tier one effects by default.

  4. Paralyzing and Anticoagulant poisons

    Paralyzing poison blocks movement keys and camera control at higher tiers, while Anticoagulant poison deals damage during certain actions.

How it compares

Full comparison

Poisons Origins is Forge-only for 1.20.1 and is not open source. JDi Origins is open source under the MIT License and runs on Fabric and Forge for 1.20 – 1.20.1, so its loader support is wider. Poison Immunity is optional on the client or the server, which differs from the required client and server setup of The poisoner.
