# Key Fragments

{% hint style="info" %}
All Key Fragment recipes have a 2 hour cooldown, but the cooldown is **not shared**. For example, this means you could craft a Key Fragment using Ghast bits and then immediately craft another Key Fragment using Enderman bits, but you would not be able to craft a Key Fragment using Ghast bits again for 2 hours.
{% endhint %}

[Spawner Key Fragments](https://reasonfounddecoy.gitbook.io/mctantrum-wiki/economy/bits-heads-and-spawners#bits-for-crafting-purposes) are an ingredient to craft [Spawner Keys](https://reasonfounddecoy.gitbook.io/mctantrum-wiki/economy/bits-heads-and-spawners#heads-for-crafting-purposes).

As shown by each recipe, you can craft a Key Fragment by using stacks of any type of mob bits. These cannot be mix-and-matched! They must all be the same type of bit for each one.
