Trinkets

Trinkets are a kind of collectible with their designated slot that provide passive bonuses. Typically, only one trinket can be carried at a time and must be dropped if the player wishes to carry another.

Fiend Folio adds 258 trinkets to the game, including a new category of trinkets known as "rock trinkets" that are mostly exclusive to one character, Golem.

This page is about Trinkets added in Fiend Folio. More information about Trinkets in general can be found in the vanilla page.

Rocks

Rocks are special kinds of trinkets added in The Reheated Update that replace regular trinkets when playing as Golem. Rock trinkets are unable to appear for other characters outside of use of certain items, such as Golem's Rock and Soul of Golem.

Rock trinkets are separated into three types:

• Fossils have special effects when crushed by the Bismuth Golem.
• Geodes have increased power and/or additional effects if the player is holding another geode.
• Normal Rocks are rock trinkets that do not fall in the former two criteria.

Each rock trinket can also come in one of six possible "rarities" — Common, Rare, Fiendish, Self Insert, Extremely Rare, and Unobtainable. The rarity of a rock trinket dictates how likely they are to appear.

There are a total of 185 rocks that Golem can collect, separated into 122 normal rocks, 33 Fossils, and 30 Geodes.

Extras

When playing as Golem, most standard trinkets will be rerolled into another pickup as they spawn. However, some standard trinkets will not. These are:

• Petrified Poop, Lucky Rock and Shiny Rock from the vanilla game.
• Fool's Gold, Massive Amethyst and Top Rock from the Fiend Folio MOD.

Additionally, Petrified Poop is treated as a fossil, and will activate the A Card Against Humanity effect when crushed.

Notes

• Geode Fossil is a unique rock trinket, as it counts both as a fossil and as a geode.
• Some rocks exist to replace set trinket drops when playing as Golem:
  • Counterfeit Penny is replaced by Ore Penny.
  • The Left Hand is replaced by The Left Fossil.
  • Swallowed Penny is replaced by Swallowed Geode.
  • Umbilical Cord is replaced by Umbilical Geode.
• Two of the lesser-used rarities, those being Extremely Rare, Self-Insert, are rarer than Fiendish and are some of the rarest Rocks in the game. Rocks with the Unobtainable rarity are unable to drop naturally at all.

Trivia

• The initial Afterbirth+ release of Fiend Folio only had 10 trinkets.
  • The Reheated Update added 39 trinkets for a total of 49, without including the rock trinkets or sub-variants of trinkets such as Tattered Frog Puppet or Shattered Cursed Urn.
