Description
Bloodlines
This is an addon for Vampirism that adds a Bloodline mechanic for vampires and hunters, changing the way you play. For more information, use the in-game GuideAPI Vampirism Guidebook and check the Bloodlines chapter.
Bloodline Mechanics
Joining a Bloodline
In order to join a Bloodline, a player follow the corresponding joining quest for each bloodline, this can be found in the quest book or in the joining section under each Bloodline no this page. Bloodline Fangs are also provided as a creative only item for modpack creatores to use.
Leaving a Bloodline
In order to leave a Bloodline, a player can use the Purity Injection. This can be crafted with an empty syringe, milk bucket and golden apple.
Levelling & Skill Tree
Bloodlines have a Skill Tree and a Rank. You can increase your Bloodline Rank by doing quests at a faction representative. This will enhance the innate aspects of the Bloodline, as well as furthering the Skill Tree.
The Bloodline Skill Tree can be accessed from Vampirism's Skill Tree Menu. Each Bloodline Skill Tree follows a general path with skills branching out from the "Bloodline Rank Skills". These are special skills that cannot be unlocked. Instead, they are automatically given when you level up your Bloodline Rank.
Additionally, skills from the Bloodline Tree require their own bloodline perk points instead of regular skill points. These are gained by doing quests from the faction representative, like the levelling quests.
Hunter Bloodlines
Gravebound Bloodline
Gravebounds are a unique and rare form of Vampire Hunter. They have embraced undeath to defeat their enemies, their hunger bar is replaced with a soul meter, which can only be replenished by devouring the souls of their enemies. While they do not need to eat, they have significantly reduced natural healing, reduced XP gain and worse trade prices. They make up for this with near immortality and a set of powerful abilities.
Gravebounds also require a Phylactery. If this is destroyed, their max souls will be significantly reduced. The Phylactery can also store souls using a Soul Binder, which can also be used to bind to a new Phylactery. The total amount of souls that can be stored is based on the amount of creatures devoured.
- Mist Form - Automatically unlocked with Rank 3, instead of dying a Gravebound will go into Mist Form automatically, if they have enough souls. They can then choose to resurrect themselves.
- Ghost Walk - Consumes a significant amount of souls, but allows them to walk through most objects
- Phylactery Teleportation - In exchange for some souls, teleports them to their Phylactery.
- Possession - Allows them to take control of certain mobs, particularly undead mobs, but also villagers, silverfish and creepers. They can attack and interact using that mob.
- Soul Infusion - Consumes some souls to quickly regenerate health.
Joining
To become Gravebound, you must create both a Rending Elixir and Heinous Elixir, and create your own Phylactery. Place down the Phylactery, then drink both the Heinous Elixir and the Rending Elixir. If you die from this, you are resurrected at the Phylactery as a Gravebound
To get corrupted blood samples, you can use a stake on bloodknight vampires.
Vampire Bloodlines
Bloodlines significantly change the way you play as a Vampire. While each new bloodline rank may come with some penalties, it will also allow you to unlock powerful new skills. Most skills, including penalties, will become more potent with higher bloodline ranks. Each bloodline comes with 4 Bloodline Ranks, enhancing their innate abilities and gaining the ability to unlock new parts of their Skill Tree.
Mob Bloodlines
Mobs also have Bloodlines. The type of bloodline they receive is data driven and based on spawn location. For example, Ectotherms are more likely to spawn in cold biomes, whilst Zealots are more likely to spawn deep undergorund.
In addition to this, vampires with bloodlines can have their skin texture chosen based on their bloodline available. By default, the existing vampire skins are repurposed for this, but in the future or for modpacks each bloodline can have different skills.
Some bloodlines may attack each other. For example, mobs of the Bloodknight bloodline will attack all other bloodlines. Again, this is data-driven so can be customised with a datapack.
Noble Bloodline
The Noble Bloodline are typically more fragile than other vampires, they take more damage and have less health. However, the threat of the Sun and Fire is less pronounced for them.
Some of their unlockable skills include:
- Slower Sundamage, They can stay out in the sun for longer without feeling the negative effects
- Sanguine Delicacyy, They will gain more nourishment from drinking blood directly from mobs
- Faster Bat Flight
- Bottomless Chalice, Allows access to a chalice that can store huge amounts of blood
- Intrigue & Flank, Increased damaging when attacking from behind and the ability to teleport behind creatues that can't see you
Joining
To become a Noble, you must already be a Rank 2 Vampire Lord. You must then craft a Lordslayer injection and find a Vampire Baron. Corrupted Blood Samples can be dropped from Vampires when killed with a Heartstriker or Heartseeker, or can be found in chests within Vampire Crypts That Vampire Baron must be brought to under 30% health, and should have the Weakness affect applied to him. Then, attack the Baron with the Lordslayer injection to become a Noble

Zealot Bloodline
The Zealot Bloodline are used to a life underground, and as such take significantly more sun damage. However, they need to drink less blood and can mine faster.
Some of their unlockable skills include:
- Flesh Eater, They can consume Rotten Flesh for blood
- Shadow Step, Teleport between dark areas
- Dark Cloak, Invisibility at wall in dark areas
- Wall Climbing
- Underground Export, Faster movement on Stone-like materials.

Deep underground in the Deep Dark biome there are small shrine structures. In the centre, there is an altar. As a vampire, crafting and using a Zealot Ritual Catalyst on this altar will start a ritual, leading to you becoming a Zealot

Ectotherm Bloodline
The Ectotherm Bloodline live in the frigid cold and underwater. They take more fire damage and are weakened in hot areas or biomes. However, they have significantly faster swim speed and have more innate power related to their bloodline than other bloodlines. This includes gaining access to the 'Lord of Frost' action innately at Rank 2, which is further upgraded by skills
Some of their unlockable skills include:
- Fishmonger, Raw Fish can be eaten to gain blood

Joining
To become an Ectotherm, you must create and drink the Freezing Elixir. Frozen Blood Samples for crafting this are found by killing Ectotherm Vampires using a Heartstriker or Heartseeker. Ectotherms are found commonly in cold biomes. The Freezing Elixir will apply a temporary effect, and if you die from Sundamage whilst submerged in shallow water and under the effects of the Elixir, you will become an Ectotherm

Bloodknight Bloodline
The Bloodknight Bloodline are a strain that primarily feast on the fresh blood of other vampires. As a result, they lose blood slower but other sources of blood are not as nourishing.
Some of their unlockable skills include:
- Daywalker, Continuously consume blood, but receive sun immunity
- Still Water, Gain a large amount of blood from drinking Vampire Blood Bottles
- Blood Extraction, Extract Vampire Blood Bottles from Vampires
- Blood Hunt, Continuously consume blood, but turn invisible

The elixir will apply many negative effects for 30 seconds, but if you survive you will become a Bloodknight
