Curse Thorn

Vanguards of the Curse Thorn, also known sometimes as Knights of the Black Rose, learn an ancient hag curse to punish others for damaging their loved ones. Originally the curse was created by a hag to punished lovers, but the hag was defeated and the curse was later transformed into a magic to protect. Up to this day, Black Thorns teach their magical secrets from master to apprentice to maintain the power of the curse now turned into a blessing.

Blessing of the Rose

Starting at 3rd level, you can use your ancient magic to bless a creature. As an action, you can touch a willing creature other than you, until the end of the next long rest, the creature is blessed. Once per turn, when a creature deals damage to a blessed creature, that creature takes 1d4 magical piercing damage. You can only have one creature blessed at a time.

Some effects of this calling forces creatures to make a saving throw. The DC equals: 8 + your Constitution modifier + your proficiency bonus

Flourishing Rebuke

Additionally at 3rd level, you learned to manifest the suffering of the ones you bless as punishment for the aggressor . When a creature you can see within 120 feet of you damage a blessed creature, you can expend a focus die to make thorns appear on the attacking creature. The creature must succeed on a Constitution saving throw or take 4d4 piercing magical damage as thorns sprout under their skin.

Curse of the Thorn

At 6th level, you learned how to curse others with your magic. As a bonus action you can choose a creature within 30 feet from you, the creature must succeed on a Charisma saving throw or becomes cursed for 1 minute. If a cursed creature deals damage to a blessed creature the cursed creature receives half the damage they dealt as necrotic damage. At the end of each of its turns, a cursed creature can reroll the saving throw, at disadvantage if it damaged a blessed creature that turn, on a success the creature stops being cursed.

The cursed creature treats the aura of your timely aid as difficult terrain.

Once a creature fails the saving throw you cannot use the feature until you finish a short or long rest. The curse also ends if a Remove Curse spell is cast on the cursed creature.

Blessed Garden

At 11th level, you have become more proficient in the art of blessing. You can have up to three blessed creatures at the same time. If you try to bless a fourth creature, the blessing disappear on all other creatures.

Deeper Roots

Also 11th level, the strength of the curse you impose increases, making it much harder to remove. When a cursed creature deals damage to a blessed creature, it automatically fails the saving throw to end the curse that turn. Additionally, you can use your Curse of the Thorn feature twice per short or long rest.

The Black Rose

At 17th level, the power of your blessing and curse reaches its maximum. Once per turn, blessed creatures add a 2d4 to their saving throws against effects caused by cursed creatures and cursed creatures subtract 2d4 to their first attack roll when attacking a blessed creature.

Additionally if a cursed creature misses an attack it made against a blessed creature, it takes half of the damage it would have dealt as necrotic damage.
