As an action, you unleash a bloodcurdling howl. Each creature within 30 feet of you that can hear you must succeed on a Wisdom saving throw or become frightened of you until the end of your next turn. If a creature fails its saving throw by 5 or more, it is stunned while frightened in this way. A creature that succeeds on its saving throw is immune to this blood curse for the next 24 hours.
You can choose any number of creatures you can see to be unaffected by the howl.
Amplify. The range of this curse increases to 60 feet.
As a bonus action, you attempt to bind a Large or smaller creature you can see within 30 feet of you, which must make a Strength saving throw. On a failure, the cursed creature’s speed is reduced to 0 and it can’t use reactions until the end of your next turn.
Amplify. This curse lasts for 1 minute and can affect any creature regardless of size. The cursed creature can repeat the saving throw at the end of each of its turns, ending the curse on itself on a success.
When a creature you can see within 30 feet of you makes an attack, you can use your reaction to roll one hemocraft die and subtract the number rolled from the creature’s attack roll. You can choose to use this feature after the creature’s roll, but before the DM determines whether the attack hits or misses.

Also at 1st level, you gain the ability to channel—or sometimes sacrifice—a part of your vital essence to curse and manipulate creatures through hemocraft magic. You know one blood curse of your choice, detailed in the “Blood Curses” section at the end of the class description. You learn one additional blood curse of your choice at 6th, 10th, 14th, and 18th level. Each time you learn a new blood curse, you can also choose one of the blood curses you know and replace it with another blood curse..
Each time you use your Blood Maledict feature, you choose which curse to invoke from the curses you know. While invoking a blood curse, but before it affects the target, you can choose to amplify the curse by taking necrotic damage equal to one roll of your hemocraft die. This damage can’t be reduced in any way. An amplified curse gains an additional effect, noted in the curse’s description. Creatures that do not have blood are immune to blood curses unless you have amplified the curse..
Once you use this feature, you must finish a short or long rest before you can use it again. You can use Blood Maledict twice between rests starting at 6th level, three times starting at 13th level, and four times starting at 17th level.
When a creature you can see within 30 feet of you takes damage from an attack or spell, you can use your reaction to temporarily weaken its resilience. Until the end of the target’s next turn, it loses resistance to all the damage types dealt by the triggering attack or spell (including for that triggering effect).
Amplify. The target instead loses invulnerability to the damage types of the triggering attack or spell, but has resistance to those damage types until the end of its next turn.
When a creature you can see within 30 feet of you drops to 0 hit points, you can use your reaction to instill that creature with a final act of aggression. The creature immediately makes one weapon attack against a target of your choice within its range.
Amplify. You can first cause the cursed creature to move up to half its speed, and you grant a bonus to its attack roll equal to your Hemocraft modifier (minimum of +1).
As a bonus action, you mark a creature that you can see within 30 feet of you. Until the end of your turn, whenever you hit the cursed creature with a weapon for which you have an active crimson rite, you roll an additional hemocraft die when determining the extra damage from the rite..
Amplify. The next attack roll you make against the target before the end of your turn has advantage.
As a bonus action, you harry the body or mind of a creature within 30 feet of you, making them susceptible to forceful influence. Until the end of your next turn, Charisma (Intimidation) checks made against the cursed creature have advantage.
Amplify. The next Wisdom saving throw the cursed creature makes before this curse ends has disadvantage.
At 1st level, you have survived the Hunter’s Bane—a dangerous, long-guarded ritual that alters your life’s blood, forever binding you to the darkness and honing your senses against it. You have advantage on Wisdom (Survival) checks to track fey, fiends, or undead, as well as on Intelligence checks to recall information about such creatures.
The Hunter’s Bane also empowers your body to control and shape hemocraft magic, using your own blood and life essence to fuel your abilities. Some of your features require your target to make a saving throw to resist the feature’s effects.
The saving throw DC is calculated as follows:
Hemocraft save DC = 8 + your proficiency bonus + your Hemocraft modifier (your choice between Intelligence or Wisdom)
Upon reaching 20th level, your mastery of blood magic reaches its height, mitigating your sacrifice and empowering your expertise. Once per turn, whenever a blood hunter feature requires you to roll a hemocraft die, you can reroll the die and use either roll.
Additionally, whenever you score a critical hit with a weapon for which you have an active crimson rite, you regain one expended use of your Blood Maledict feature.
At 2nd level, you learn to invoke a rite of hemocraft that infuses your weapon strikes with elemental energy. As a bonus action, you can activate any rite you know on one weapon you’re holding. The effect of the rite lasts until you finish a short or long rest. When you activate a rite, you take necrotic damage equal to one roll of your hemocraft die. This damage can’t be reduced in any way.
While the rite is in effect, attacks you make with this weapon are magical, and deal extra damage equal to your hemocraft die of the type determined by the chosen rite. A weapon can hold only one active rite at a time. Other creatures can’t gain the benefit of your rite.
You choose one rite from the crimson rites below when you first gain this feature. You learn an additional crimson rite at 7th level, and again at 14th level.
The extra damage dealt by your rite is fire damage.
The extra damage dealt by your rite is cold damage.
The extra damage dealt by your rite is lightning damage.
At 6th level, when you damage a creature with a weapon for which you have an active crimson rite, you can channel hemocraft magic to sear an arcane brand into that creature (no action required). You always know the direction to the branded creature as long as it’s on the same plane as you. Further, each time the branded creature deals damage to you or a creature you can see within 5 feet of you, the branded creature takes psychic damage equal to your Hemocraft modifier (minimum of 1).
Your brand lasts until you dismiss it or until you use this feature to apply a brand to another creature. Your brand can be dispelled with dispel magic, and is treated as a spell with a level equal to half your blood hunter level (maximum 9th level).
Once you use this feature, you can’t use it again until you finish a short or long rest.
When you reach 9th level, you gain a supernatural talent for discerning the secrets surrounding mysterious relics or places touched by evil. Whenever you make an Intelligence (History) check to recall information about the sinister or tragic history of an object you are touching or your current location, you have advantage on the check. At the DM’s discretion, a suitably high roll might cause your character to experience brief visions of the past connected to the object or location.
