Sorcerous Origin: Blackthorn Lineage

Somewhere in your lineage, an ancestor entered and made a pact with the Blackthorn Grove, replacing their heart with one crafted from the essence of the Grove itself. Working with plants has always come naturally to you, but one day your magical power awakened. In defense of your life or in pursuit of your heart’s deepest desires, the strange arcana of the Blackthorn Grove sprouted within your veins, giving you power to use as you see fit.

Watcher in the Maze

At 14th level, you attune yourself to the Maze of Blood.
You ignore difficult terrain. You can ignore magical and
nonmagical effects that would cause plants to hinder or
damage you, such as from the effect of the entangle spell.
Whenever you use your Sleeper in the Field feature and the
target’s hit points are greater than the number rolled, you can
use your bonus action to deal magical piercing damage equal
to half the number rolled to the target.

Heart of the Wilderness

At 18th level, while you maintain concentration on a spell,
you can have blackthorn vines swarm around you in a 30-foot
radius, acting as difficult terrain for hostile creatures.

Origin Spells

When you choose this sorcerous origin, you gain access to the
following spells, which do not count against your spells known
but can only be cast once you reach the required sorcerer level.

Blood of the Dark Forest

When you select this origin at 1st level, your spirit aligns to the
power of the Grove, calling to the cycles of regrowth. You learn
the druidcraft cantrip. When your Spellcasting feature lets you
learn or replace a sorcerer cantrip or a sorcerer spell of 1st level
or higher, you can choose the new spell from the druid spell
list or the sorcerer spell list. You must otherwise obey all the
restrictions for selecting the spell, and it becomes a sorcerer
spell for you.

Sleeper in the Field

Also at 1st level, whenever you cast a spell using a spell slot
of 1st level or higher, you can choose a creature that you can
see within 30 feet of you. Roll 1d10 for each level of the spell
slot you expended. If the total is equal to or greater than the
creature’s remaining hit point total, it falls asleep as though
affected by the sleep spell.

Glade Reaper

At 6th level, your connection to the Grove imbues you with
a thirst for blood and the power to claim it. When you cast a
spell on the druid spell list that deals damage by expending a
spell slot, you can spend sorcery points equal to half the spell’s
level to gain temporary hit points equal to half the damage
dealt to one creature damaged by the spell.
