Resonant Black Blood

Across the realms, few things differ enough to be considered a thing of their own. Across the vast expanse of Twilight, issues such as corruptions, maladies, curses, diseases, enchantments and the like, are in such an abundance, that one could hardly turn to one world and not find something that fits the bill. Your life had been warped by them twice now. Your home, to the curse of the demon that sought death to your adoptive kind...and now, the madness, that refused to cease even in death.

You sought answers. And yet, you may not quite have found the solution you thought you might have wanted.

For what is an antidote, but the dose of the very same poison.

Infected against your will, your body, mind and soul had been corrupted by the essence of a being greater than yourself, whose single minded purpose was the end of all things, for whatever reason his mad self had reached. And yet, neither your mind, nor your soul, nor your body, had succumbed to the worst fate that awaits those cursed by its existence. Instead, you fought against, and from the jaws oblivion, snatched back your very existence, and strengthened it further, with what once sought to destroy you.
Your body now holds a more stable form of the Corrupted King's blood, it coursing and mixing with your own within your body. Though its whispers still eat away at your sanity, their strength has lessened significantly, and what's more...it seems to now be subservient.

While Injured, you heal 1 hp at the start of your turn. While Bloodied or Critical, you take 1 damage at the start of your turn.

You may opt to share this curse with another willing creature as an action, by placing your hand on their being. When you do, your maximum health is reduced by your charisma score. This max health reduction is unavoidable by Boon of Vitality and the like, and the lost maximum health cannot be restored by any means other than the one stated later in this ability. The creature additionally receives the same regeneration ability stated above(including the damage on Bloodied/Critical states).

You can retrieve this granted corruption as a free action. It will also return to you on its own, if its recipient ends up farther than 300 feet from you, even during resonance, ending the effects of it immediately. In both cases, the maximum health lost by imbuing that specific individual is restored to you, along with the corruption, without changing your current hit point percentage relative to the maximum. Otherwise, this corruption lays dormant within the creatures indefinitely.

As an action, you can cause this corrupted blood to resonate, forming a link of sorts between you and the creatures you've bestowed this blood upon, lasting for up to one minute, at which point, the corruption ceases to resonate, and returns to you. This effect is called Resonance. This link interacts directly with your class features in the following ways:

Aura of Protection - While afflicted with the Resonance, the corrupted creatures are considered to be within your Aura of Protection's range, gaining all of its benefits.
Lay on Hands - By placing your hands upon yourself to activate this feature, you may also target any creature under the effects of Resonance as if they were the ones your hand has touched.
Channel Divinity: Sardior's Telekinetic Field - You may, as a free action, once per round, shift this field to affect one of the creatures under the effects of Resonance instead.
Font of Magic - While creating more Sorcery Points, a willing creature under the effects of Resonance can offer its own spell slots to convert into Sorcery Points. While creating a new spell slot, you may instead choose a creature under the effects of Resonance that has the Spellcasting feature, to recover their spell slot instead.
Metamagic - As a reaction, when a creature under the effects of Resonance casts a spell, you can enhance the spell with one of your Metamagic Options.
Spellcasting - Any effect that's not instantaneous, isn't a reaction, and affects only you, that had been generated from a spell you know as part of your Spellcasting feature, affects all other creatures affected by Resonance as well.(Excludes any spell learned via Ruby Weave Gem.). Concentration for such spells is held solely by you, and ends on all affected creatures once your concentration drops.
