Fermented Spider Eye in Minecraft trading

Fermented Spider Eye is one of the six things the Wandering Trader buys rather than sells. He pays 3 emeralds each and stops after 2 trades, and no job villager wants it at any tier, so that offer is the entire market for it.

Brewed from a spider eye, sugar and a brown mushroom, it exists only to turn potions into their corrupted versions. Outside brewing it has no use at all, which is what makes an offer that converts it into emeralds worth knowing. A crafting grid makes one from 1 × spider eye, 1 × brown mushroom and 1 × sugar.

The 1 trade on this item was read out of the trade files Minecraft Java 26.2 ships in its own data, checked on against the item, both amounts and the use limit. Bedrock 1.26.30.5 is read as well, and where it disagrees the row says how. Which files, and what is not checked.

Your odds of finding Fermented Spider Eye

A villager only shows part of its trade table, so knowing who trades fermented spider eye is not the same as getting it. The friendliest roll here is the wandering trader (buying pool): 33% of them carry it, so it takes about 3 of them on average before one does.

The chance is the draw size over the pool size in the game's own trade set file for that tier. The Bedrock line under it is the same sum on Bedrock's own table, which splits a tier into groups and draws out of each one separately, so the two editions often disagree. The wandering trader has no workstation and never restocks, so his row is everything that offer will ever give you, and he has no reputation to earn, so curing does nothing for him. Counted from the game's own draw sizes. How that check works.

Who trades Fermented Spider Eye, and at what price

The Wandering Trader buys Fermented Spider Eye, and pays 3 emeralds each (2 trades before it locks). It is one of only six items he takes, and each trader offers two of the six at random.

No standard villager profession lists Fermented Spider Eye in its trade table, so the trader above is the whole market for it.

How to actually get Fermented Spider Eye from the trader

The Wandering Trader is not part of any village. He arrives on his own near where you are playing, with two leashed trader llamas behind him, stays for roughly forty minutes to an hour, and then vanishes whether or not you traded with him. There is no workstation to place and no job block to break, so the usual tricks for steering a villager toward a particular offer do nothing.

Fermented Spider Eye is one of the six things he does buy, so this one runs both ways: he pays 3 emeralds each for it, and that offer locks after 2 trades because he never restocks.

Each trader carries only a slice of the full stock list, so the one standing in front of you may simply not have fermented spider eye today. If he does and you want more than one visit's worth, put a name tag on him: a named mob will not despawn, which turns a passing merchant into a permanent shop you can come back to.
