Essence of theSlayer

By drinking this Essence, you gain the capabilities of those who hunt and slay the terrors of the Moonlit World:

• A free, one-time cosmetic body resculpt to your ideal or desired appearance.

• A one-time full cure of whatever ailments, whether physical, mental, or spiritual, that currently plagues you, and any new ailments of the body, mind, or soul will be prevented from occurring. This includes things such as near/farsightedness, genetic diseases, etc.

• You gain an immunity to all mundane diseases, poisons and venom, as well as a high resistance towards being turned/converted into a creature of the night. Only those at the levels of an elder would be able to turn you into one of their kind, and even then would need to somehow immobilize you and perform hour-long foul rituals.

• This resistance also extends to supernatural influence that such beings would employ against their prey. This includes curses, hexes, and other forms of dark magic employed against you.

• You are endowed with strength, speed, and endurance that rivals Olympic gold medalists, your athletic feats able to easily break world records, with the will and resolve that allows you to keep going through any amount of hardship.

• Your mind has been enhanced, gaining a retroactive perfect memory with infinite storage and instant recall with superb indexing. Your thought processing speed also becomes faster, allowing you to read novels from cover to cover within minutes.

• Your reflexes, awareness, balance, and hand-eye coordination are enhanced to superhuman levels, to the point you have a mild combat precognition and danger sense.

• You gain the ability to heal at a vastly accelerated rate, mending broken bones in hours and regenerating lost limbs in a day. Getting decapitated will still outright kill you, for now that is.

• Your lifespan, provided that you do not die in battle, have been extended by several decades. Until your hourglass empties, you will always retain your skill, stats, and abilities obtained from this Essence or pick up in the future, never degrading from disuse. Your apparent age will also be set to the prime of your life.

• You gain a high amount of innate knowledge of things that go bump in the night, a professional scholar when it comes to the beings of night that prey upon humanity.

• Innately gain the kind of skill, abilities, training, and psyche that members of well-funded private military contractors have undergone, without negative changes to your personality and/or mental health. In addition, you can keep your cool in all forms of stressful situations.

• You can render most forms of supernatural and biological immortality invalid, making the immortal mortal. This also allows you to permanently put down what you intentionally kill - not even the remnants of your quarries will turn into wraiths.

• Yes, you can even kill spirits and even gods with this ability. Just make sure you're strong enough to do so.

• However, all the above pale to the last ability those who imbibe this Essence will possess. Unlike traditional Slayers and Hunters, those empowered by this Essence will be able to draw upon the strength of slain opponents, each life (or un-life) taken granting you more time on the mortal plane:

• Ordinary mortals, combatants and civilians alike will grant moments - minutes, at best.

• Those who affiliate with the supernatural, such as cultists and collaborators granting weeks.

• Slaying monsters and/or witches, however, will grant additional years to your life, a decade, at the very least.

• In addition to extending your lifespan through taking lives, you also grow stronger from the enemies you kill, improving existing powers and even developing new ones thematically based on those you have felled.
