Looking for the Mutation Shard or Mutation Consumable in Steal an Egg? Both searches currently point to the new Rift/Boss Shop mutation system. Here is the shortest route to the item, what is confirmed about Fractured, and what players should know before spending Boss Tokens.

Mutation Shard is a fast-rising player search term, but it is not the name currently shown in the Boss Shop. The shop listing documented in current gameplay guides is “10% Mutation Consumable.”
Because the item has a purple crystal-like appearance, some players and guides describe it as a mutation crystal. That is likely why searches such as mutation shard steal an egg are appearing.

What Does “10% Mutation Consumable” Mean?
This is the part players should treat carefully. The Boss Shop item is shown as a “10% Mutation Consumable”, but the official Rift changelog does not separately explain what the 10% represents.
Some current guides describe Fractured as providing an additional 10% money gain, while other community references interpret the 10% as a mutation application chance. Because those explanations conflict, it is safer not to present either interpretation as an official confirmed rule until the developers or the live item description clearly states it.
How to Get Boss Tokens in Steal an Egg
Boss Tokens come from the Abyss Overlord Rift boss. Rifts open on a recurring schedule, and the official Update 3 changelog confirms that defeating the Overlord awards Boss Tokens that can be spent in the Boss Shop.
Current Rift guides report roughly 1,200–1,500 Boss Tokens per successful boss clear. That amount is guide-reported rather than a fixed developer-published payout formula, so it may vary or change with later balance updates.
For the full Rift timing, boss phases, Rift Eggs and Boss Mastery, see the Steal an Egg Rift Event Guide.
What Egg Should You Use the Mutation Consumable On?
Since the Mutation Consumable costs 400 Boss Tokens, avoid using it on the first weak Egg you find. A better approach is to save it for an Egg you would be happy to keep if it hatches into a strong or rare pet.
The key rule is simple: choose the Egg before it hatches. If you are still deciding which pets are worth prioritizing, use our Steal an Egg All Pets guide and Steal an Egg Biomes guide to compare progression and pet income.
Mutation Shard vs Sakura Crystal: Do Not Mix Them Up
The Rift Mutation Consumable is separate from older Sakura mutation mechanics. Players may use similar words such as crystal or shard, but the currencies and systems are different.
| Search / Item | System | Main Use |
|---|---|---|
| Mutation Consumable | Rift / Boss Shop | Connected to Fractured Mutation |
| Mutation Shard | Player search term | Most likely refers to the Mutation Consumable |
| Sakura Crystal | Sakura / Incubator system | Used for Sakura-related mutation mechanics |
