What does Formic Rock do in Elden Ring?

Formic Rock is a useful crafting material that players can find in the Lands Between of Elden Ring.

There are many materials that can be picked up from the ground, dropped from enemies, or looted from chests and corpses. Formic Rock is a highly acidic item needed to craft Acid Spraymist.

That seems to be its only use in the FromSoftware title. Players will need to collect a handful of Formic Rock and use them as an ingredient for crafting the poisonous mist that can be spewed from the Tarnished's mouth.

The first step in using Formic Rock is finding it. There are few locations where it can be found across the Lands Between. Some are resource spawns with one being a static loot location.

Here is where Formic Rock can be obtained:

The highly acidic resource is a glowing red rock formed from solidified giant ant venom that is pretty hard to miss.

When Formic Rock has been found, players can use it in their crafting kit whenever they have the recipe for Acid Spraymist. This comes from the Perfumer's Cookbook [4] that can be bought from the Nomadic Merchant at Ainsel River.

The crafting recipe requires:

With these items, an Acid Spraymist can be made. Players use the consumable that has been created to load their mouth with acid mist and then spit it out towards their enemy.

It damages armaments with its acidic qualities and lowers attack power of whoever it hits. This can be extremely helpful for players who might have a lower defensive status than others.
