Aspect of Omniscience

A kaleidoscope of small glasslike discs rotating within and through each other, blindingly refracting light when exposed. Attunement to this Aspect by the ordinary often results in insanity and comas, though special individuals can handle the burden of knowledge. Attuning causes the creature to become incapacitated, convulsing and screaming in unknown tongues for the full hour before emerging from their terrors with no memory of the process and the Aspect embedded within them.

The Aspect gains charges equal to your character level. At any point you can regain charges by expending hit die, regaining charges equal to the hit die spent. However, you must roll the spent hit die and reduce your maximum HP by an equal amount until the end of your next long rest as you push your body beyond its mortal limits.

You can use these charges to activate the following abilities:
Wool-Proof Eyes: One Charge: As a free action you gain Truesight out to 10 feet, and can see through heavily obscured areas (darkness, fog, or dense foliage) as if it were bright light out to 60 feet. Both of these features last until the end of your turn.

Precognition- Two charges: As a reaction immediately after any d20 contest caused by you is resolved, you can rescind the action triggering the contest having seen the result before it has happened. If you repeat the rescinded action against the same target(s), the foreseen roll(s) are used again.

Glean Knowledge- Three charges: As an action, you can choose any skill, tool proficiency, or language to gain proficiency in for 1 minute. You gain expertise if you already have proficiency in the skill or tool. If you fail a check with the chosen skill or tool you immediately lose the proficiency/expertise.

Peek the Veil- Four Charges: You can cast one of the following spells without expending a spell slot or requiring material components: Scrying, Legend Lore, Contact Other Plane, and Divination. 

Additionally, while attuned you have these passive features:
Universal Understanding: You can understand creatures who speak no languages, though you only can translate base emotions or simple messages such as yes or no.
Elucidate- Once a turn when a creature fails a saving throw against a spell or ability you cause, you can learn one of the following: the creature's type, any class levels it may have, as well as a resistance, immunity, or vulnerability it has.

However, while attuned you have these passive downsides:
Above it all: You have disadvantage on Wisdom (Perception) and Intelligence (Investigation) checks (-5 to passives) as it’s difficult to focus on the here and now.
Overloaded Psyche: You have vulnerability to psychic damage, and you have disadvantage on Constitution saving throws to maintain concentration on spells as your mind is constantly overwhelmed.

Notes: Vulnerability: Psychic, Disadvantage: Perception, Disadvantage: Investigation, Disadvantage: Constitution Ability Checks, Sense: Truesight, Sense: Darkvision, i can't make the charges equal character level so PLEASE track yourself, Utility, divination, Symbiotic
