Headless Horseman Pet Traits
The Headless Horseman occasionally gives one of the other pets a unique mutation. As of the current patch, these four mutations are exclusive, and you cannot obtain them any other way. Here is how it works:
- Every 40 minutes or so, the Headless Horseman will target a pet in your garden that is at least 50 levels old for a hunt. The affected pet will revert to level one, but will gain one of these four mutations: Nightmare, Dreadbound, Spectral, and Soulflame.
Below is a table explaining what each of the Headless Horseman’s mutations does.
Pet Mutation | Pet Mutation Trait | Pet Appearance |
---|---|---|
Nightmare | Increases the pet’s size by 125 times and its passive gets a 1.22x boost. | Affected pets gain a purple translucent look. |
Dreadbound | The pet will get an additional 6 to 30 XP per second. | Dreadbound pets change their texture and look purple. |
Spectral | Pets get a 1.8x passive boost. | Spectral pets look ghostly with a bluish, transparent appearance. |
Soulflame | The pet’s passive gets a 60% boost. Additionally, every ~15 minutes, nearby fruits have a ~30% chance to gain the Burnt mutation. Rarely can plants also become Flaming. | The pet looks as if it is on fire. |
