The Forgotten

You have made a pact, though you have no memory of it. You remember nothing of this pact. You have not a single idea as to its reasoning for choosing you nor your reasoning for accepting it. All you simply realise is that your magical abilities come from a distant, unknown creature, who you hear within your mind, humming a delicate and seemingly peaceful song.

Typically, those that make this pact make it in a time where a major lie had been revealed to them within their life, or when they found out a haunting truth which the False Hydra heard. During this time, the song ,a has invaded your mind, yet you were immune to its effect, allowing it to remain within your mind like a scar, slowly growing in volume and recognition. Overtime, those stuck with hearing it control it and become able to replicate it through hums or songs. In doing so, they access the powers which the hydra uses.

Communion with this entity is almost impossible, yet some with its abilities swear whenever they concentrate, they can hear a word or two reverberate from within the humming within your mind.

 

Distant Hum

Starting from 1st level, you can always hear a slight humming coming from somewhere, should you focus on it for long enough, it grows in power, fixing your mind on your goals and ambitions. You are immune to the song of the false hydra, and have advantage on spells or effects that would attempt charm or frighten you.

Hum of the Hydra

Starting from 1st level, you may begin to hum a strange song, which seems to reverberate and shake the minds of those around you who hear it. As an action, you can begin humming in a very quiet, docile tone. Until the end of your next turn, any creature that saw you within 60 feet whilst you used this feature and would attempt to make an attack against you would do so at disadvantage, as the humming meddles with their mind, distracting them and making you more difficult to perceive. If a creature would manage to successfully hit you whilst you are under this effect, your hum temporarily shifts into a wail, dealing psychic damage equal to your charisma modifier (minimum 1) to all creatures of your choice within 5 feet. This part of the feature only activates once every time you use the Hum of the Hydra feature.

Song of the False One

Starting from 6th level, the humming shifts from its quiet, docile state to a more peaceful, yet disturbing piece, seeming more like a song rather than a hum , which you can choose to copy and sing for yourself. Whenever you use your hum of the hydra feature, all creatures of your choice within 30 feet of you must make a wisdom saving throw against your spell casting DC. On a failure, you are under the invisibility spell to them until the end of your next turn. This effect ends early for them if you make an attack against them, but only after the attack is made.

In addition your wail feature increases to 10 feet.

False Hydra's Symphony

Starting from 10th level, your mind has shaped itself to retain and accept the song within your mind, leading it to become more audible than it has ever become before. It now sounds to you like a sorrowful symphony, filled with anguish and an insatiable hunger.

As a bonus action, you can begin to sing the song you have now begun to hear constantly within the back of your mind. All creatures of your choice within 90 feet of you must make a wisdom saving throw against your spell casting DC. On a failure, you remain under the effect of greater invisibility to them. At the end of each of these creatures turn, they may make the same check to end the effect. Should a creature attempt to cast see invisibility, it will have no effect, however, people with true sight will still be able to see you.

Once you use this feature, you cannot do so again until you finish a short or long rest.

The Forgotten One

Starting from 14th level, your mind has come to a rest, allowing you to choose when to listen to the symphony which resides in your mind. However a more haunting sound has appeared. Every now and then, a ghastly song aches within your mind, taking the form of random headaches.

As an action, you select a creature of your choice you can see within 100 feet of you. You then begin to sing a haunting song which only you and the creature selected can hear. This creature makes a wisdom saving throw against your spell casting DC. On a failure, they forget your existence completely for 1 minute. You can only have one creature under this affect at a time. They have no recollection of your identity, nor your impact on the world or anything that would link to you. Even if you stand in front of them and interact with things around them, they cannot perceive you in any way nor understand that it was you that interacted with the object, often ignoring it completely. The creature would make its own mind up to why there are gaps in information if it has any, and would carry on their life as if you had never existed. This effects ends early if you cast a spell, make an attack on the creature, or physically touch them. Whenever a creature is affected by this, they do lose their frightened or charmed condition if you were the one they were charmed or frightened by. After the 1 minute, or if it ends early, they regain all memories of you. Should this feature be used on the same creature more than once, they make an additional check. On a failure, the feature remains for 1 hour instead. If they are already under the effect, they roll at disadvantage. Should they succeed, the entire effect ends early.
You can also choose to make a creature forget about someone else. TO do so, you must be touching the create you want the intended target to forget about when activating this feature.

When you first use this feature on a creature and they succeed the saving throw, you mind is shattered as the magic fails, and the song damages you psychically . You become unable to use any features given to you by the false hydra for 1 minute.

This affect can also end early if the creature is affect by a spell similar to the greater restoration spell or higher.

You can use this feature twice, in which all expended uses are returned on a long rest.
