An Aperial is a Sorcerer who lacks innate arcane abilities; rather, they consume the magic from the world around them, augmenting their physical, mental, and magical forms to become a being of immense power, for better or worse. To harness such capacity requires a genius mind, an unbreakable will, and a willingness to forgo the confines of your mortal form.

Aperial Knowledge

Your morphology now allows you the ability to mimic and perfect the arcane abilities of the foes you face. When you or an ally within 30ft are the target of a hostile creatures non-weapon ability, you may attempt to use your reaction to attempt to perform an Apery.

To do this, make an Intelligence Saving Throw. The DC is equal to 8 + half the creatures CR. On a success, you may use your next action to absorb the weave energy of the strike. When you do this, you are considered incapacitated until the start of your next turn. On a failure, you suffer one level of exhaustion.

At the end of your next long rest, you may add any ability you successfully copied into your Aperial Form list. You can learn any number of these abilities, however you may only prepare a number of Aperial Knowledge equal to half your Sorcerer Level (rounded down) + Your Intelligence Modifier. You can change these Aperial Knowledges at will at the end of a Long Rest. Any ability you copy uses your spellcasting modifier for attack rolls, and your Sorcerer Spell Save DC for Saving Throws.

You may not gain Aperial abilities from a Construct, Humanoid, Undead, or any creature with class levels. You may not learn any Legendary, Lair, or Mythic Actions. You cannot use this ability on a creature whose CR is greater than your level.

Once you take this reaction, regardless of your success or failure, you cannot do so again until you take a Long Rest.

Aperial Expression

Having perfected the abilities you've mimicked, you can now utilize them in battle.

You do not need to provide any material components for spells or abilities cast in this way, unless they are costly. You may, as an alternative, spend a number of sorcery points equal to the spell level required to activate the ability in order to cast it.

Abilities learned this way may be affected as normal by Metamagic once you've gained that feature at 3rd level.

Aperial Ingenuity

Your studies of the function of the weave and how they express themselves has made you an expert in numerous fields.

You gain two additional skill proficiencies, which you may choose from Arcana, History, Investigation, Nature, or Religion. If you are already proficient in the skill you choose, you may gain expertise instead.

Aperial Enhancement

At 6th Level, you now have the ability to not only enhance your blows, but your mind, body and spirit. Over the course of one minute, you may attempt to Apery the Weave Essence of one deceased creature (following the same restrictions as Aperial Knowledge). To do this, make an Intelligence Saving Throw. The DC is equal to 8 + half the creatures CR. On a failure, you gain 1 Level of Exhaustion. On a success, you may Apery one defensive or passive feature of the creature and add it to your Aperial Knowledge.

Additionally, for every Aperial Enhancement Ability you have active, you are forced to permanently expend 1 Sorcery Point to maintain that ability.

Once you make an Aperial Enhancement Saving Throw, you may not attempt to do so again until the end of your next Long Rest, regardless of success.

Aperial Supreme

At 14th Level, your practice of Apery has made it so that you have not only copied the abilities you have witnessed, but have adapted them to perfection. You now no longer have to expend a Spell Slot for Aperial Knowledge abilities that use a Bonus Action or Reaction. Once per long rest, you may use an Aperial Knowledge you have prepared without expending a Spell Slot. This increases to twice per long rest a Level 17, and three times per long rest at Level 20. Additionally, you are no longer bound by the CR of the creatures you use Apery on.

Aperial Ascendant

Having delved into the countless secrets of the Weave, having travelled across the world and many realms, your mortal form has evolved to develop an Ascendency.

At 18th level, though still limited in the number of Apery you can prepare, Aperial Enhancements no longer require Sorcery Points to maintain. You can now use your Arcane Knowledge to prepare one Legendary Action, which does not require a spell slot to activate.
