Extract Poison Mod FAQ

Craft or obtain an empty glass bottle, then walk up to a Cave Spider, Pufferfish, or Bee and right-click it. You don't need to kill the mob—just get close and the bottle fills with poison.

Cave Spiders, Pufferfish, and Bees. Pufferfish support requires Minecraft 1.13 or newer, and Bees require 1.15 or newer.

No. You only need to right-click the mob with an empty glass bottle while standing close enough. The mob stays alive and can be milked again after its cooldown.

The most common causes are an empty hand instead of a bottle, the mob not being a supported type, or the per-mob cooldown still being active. Wait for the cooldown to expire and try again with an empty glass bottle.

By default each mob has a cooldown of 60 seconds before you can extract from it again. This is controlled by the extractDelayMs setting in the config file.

Open the mod's config file and edit the extractDelayMs value, which is measured in milliseconds. Lower it for faster farming or raise it to make poison harder to obtain.

Yes, but only after that mob's cooldown has elapsed. Each individual mob tracks its own timer, so you can rotate between several mobs to keep extracting.

It works on servers, but the config is server-side, so the cooldown is set by whoever runs the server. If extraction seems slow or blocked, check with the server admin about the extractDelayMs value.

Yes. Because extraction is a right-click interaction with a cooldown, you can build a farm that keeps mobs in place and uses a dispenser or player-simulating setup to bottle them on a timer. Match your farm's cycle time to the extractDelayMs value so you don't waste attempts.

It's a minimalist mod with no world generation or heavy ticking logic, so performance impact is negligible. Conflicts are rare, but other mods that change right-click interactions on the same mobs could interfere with extraction.
