Biblioape

Arcane Vision
The Biblioape does not see the world as other creatures do. Instead, it perceives the flow of magical energy and knowledge as if they were a visible light spectrum. This gives the Biblioape the ability to:

Detect magic at will (no action required) within a 120-foot radius.

See the hidden arcane energies of creatures, objects, and locations. The Biblioape can instantly recognize magical auras and the arcane power contained within.

Knowledge Hunger
The Biblioape feeds on the flesh and memories of sentient creatures, gaining sustenance from their arcane knowledge. When the Biblioape reduces a creature to 0 hit points with its bite or claw attack, it consumes part of the creature's magical essence and may learn one random spell or magical secret the creature knew. The knowledge gained may be imperfect or incomplete, and the spell may be unstable. The Biblioape can cast the learned spell once without expending a spell slot, but the spell has a 50% chance of failing or causing wild magic effects.

Exhalation of Knowledge
Once per day, the Biblioape can exhale a cloud of arcane energy that contains volatile and fragmented magical knowledge. All creatures within a 20-foot radius must make a DC 17 Intelligence saving throw or suffer the effects of confusion for 1 minute. In addition, the creatures may gain unintended magical knowledge, which could result in:

A random magic item being materialized in the area (determined by the DM).

A spell scroll of a random spell appearing within 5 feet of the Biblioape.

The Biblioape can use this ability again after a long rest.

Resilient to Magic
The Biblioape’s body is composed of magical scrolls and arcane energy, which makes it highly resistant to most forms of magic. It has advantage on saving throws against spells and other magical effects, except for fire-based magic.

Multiattack
The Biblioape makes two attacks: one with its bite and one with its claws.

Bite
Melee Weapon Attack: +8 to hit, reach 5 ft., one target.
Hit: 18 (2d10 + 5) piercing damage.

Claw
Melee Weapon Attack: +8 to hit, reach 5 ft., one target.
Hit: 15 (2d8 + 5) slashing damage.

Scroll Lash (Recharge 5-6)
The Biblioape can lash out with a fragmented scroll from its body. This scroll lash deals 4d6 force damage and may entangle the target. The target must make a DC 17 Dexterity saving throw or become restrained by the scroll’s arcane bindings for 1 minute. The restrained creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Tear of Knowledge
As a bonus action, the Biblioape can tear a piece of its own body (a fragment of scroll) and expel arcane energy in a 5-foot cone. All creatures within the cone must make a DC 17 Wisdom saving throw or suffer psychic damage equal to 2d8 plus the Biblioape’s Intelligence modifier, and be frightened for 1 minute.

Evasive Knowledge
When the Biblioape is hit by an attack, it can use its reaction to teleport up to 30 feet to an unoccupied space it can see, leaving behind a trail of arcane scribbles in the air. This teleportation leaves the attacker confused, causing it to have disadvantage on its next attack roll.
