Base Class: Druid
Druids who choose this circle at 2nd level learn how to use their bramble vines for offensive and defensive purposes in return for the ability for the bramble vine to have a host.
Bramble Spores
Starting at 2nd level your bramble vine starts to produce spores. When a creature you can see moves into a space within 10 feet of you or starts its turn there, you can use your reaction to deal 1d4 necrotic damage to that creature unless it succeeds on a Constitution saving throw against your spell save DC. The necrotic damage increases to 1d6 at 6th level, 1d8 at 10th level, and 1d10 at 14th level. You also learn the Thorn Whip cantrip if you do not have it already, as the vine can also function itself towards and enemy and borrows under the ground before arising underneath the target, possibly doing damage and pulling them closer to it's main host [ you ].
Knowledge Of Bramble
Starting at 3rd level you gain special knowledge of your bramble vines, As an action, you can expend a use of your Wild Shape feature to instruct your bramble vine to aid you by helping you infuse your magic into it's spores covering you, rather than transforming into a beast form, and you gain 4 temporary hit points for each level you have in this class. While this feature is active, you gain the following benefits:
When you deal your bramble spores damage, roll the damage die a second time and add it to the total.
your melee weapon attacks deal an extra 1d6 necrotic damage to any target they hit.
Infest the dead
Starting at 6th level your bramble vines are powerful enough to infest a dead medium or below humanoid or animal, the dead creature then rises as an undead. If the creature is a humanoid and is a corpse it uses the zombie stat block, likewise if you target bones it will become a skeleton and uses the skeleton stat block. If the creature is a animal on the other hand if it is a corpse or skeleton it rises and uses the creatures stat block ( if you want ) otherwise depending on what you targeted it well become a zombie ( corpse ) or skeleton ( bones ) using their stat block. When the creature rises like this it will have a green vine growing over it with a yellow bulb being highly visible. The corpse or bones do not need to be complete to raise the undead. At 6th level the animal you raise can only use it’s stat block if the creature is CR 1/2 or below, this increases to CR 1 at 10th level. If you present the undead with a fresh corpse before 24h has past the bramble vine will greedily consume the corpse acting as if you had used the summon undead spell on the undead to reassert control, this cannot be done any other way. If you forgo feeding the undead a fresh corpse or give it a old corpse it will wait and become hostile to you when you least expect it, often provoking attacks of opportunity for the undead. The bramble vine infesting the corpse is semi sentient so be wary of that.
Bramble Vine spore flight mutation
At 10th level, you gain the ability to seed an area with your bramble vines powerful spores. As a bonus action while your Knowledge Of Bramble feature is active, you can gently blow your vines spores up to 30 feet away, where they swirl in a 10-foot cube for 1 minute. The spores disappear early if you use this feature again, if you dismiss them as a bonus action, or if your Knowledge Of Bramble feature is no longer active. Whenever a creature moves into the cube or starts its turn there, that creature takes your Bramble Spores damage, unless the creature succeeds on a Constitution saving throw against your spell save DC. A creature can take this damage no more than once per turn. While the cube of spores persists, you can't use your Bramble Spores Reaction Feature.
Full Infestation
At 14th level, the bramble vine has had you as it's primary host for so long it has mutated and changed you, you can't be blinded, deafened, frightened, or poisoned, and any critical hit against you counts as a normal hit instead, unless you're incapacitated also you can a weakness to radiant damage, your bramble vine is now so powerful it can send out a runner into a dead humanoid or animal corpse that you had spoken to before death and was willing and the vine will infest the corpse, putting the soul of the humaniod or animal back into the corpse while allowing it to stay in the body intill you die, the now undead creature has the following benefit:
It gains the ability of a white, allowing it to raise any humanoid it kills as a zombie after 24 hours, you can only have one [ immortal graveviner ].
Starting at 16th level you also gain the ability to sap life from you spore grove so that you may live longer, for every plant in your spore grove you can sacrifice one to gain an extra year of life, although you can still run out of plants in your spore grove and may still die from other reasons such as a God or Demigod killing you themselves.
