Descripción
The ultimate expression of mind flayer domination, an elder brain sprawls within a vat of viscous brine, cared for by mind flayer minions as it touches the thoughts of creatures near and far. It scrawls upon the canvas of the creatures' minds, rewriting their thoughts and authoring their dreams.
An elder brain sustains itself by consuming the brains of other creatures. If its mind flayer servants don't bring meals directly to it, the elder brain reaches out with tendrils of thought, compelling creatures to come to it so that it can feed on them.
When a mind flayer perishes, the elder brain's servants feed its brain to their master, which then absorbs the knowledge and experience contained therein. Mind flayers conceive of this oneness with the elder brain as a sacred state akin to an afterlife.
Hive Mind
Elder brains are so-called among non-illithids because they act as the central communication hub for an entire mind flayer colony, just as a brain does for a living body. Linked to the elder brain, the colony acts like a single organism, acting in concert as if each illithid were the digit of a hand.
An elder brain considers itself and its desires the most important things in the multiverse, and the mind flayers in its colony nothing more than extensions of its will. Each presides over its colony according to its own unique personality and storehouse of collected knowledge and experience. Some elder brains reign as tyrants, while others serve as sages, counselors, and repositories of information and lore for the mind flayers that protect and nourish them.
An Elder Brain's Lair
The lair of an elder brain lies deep in the heart of a mind flayer colony. The brain dwells in a dimly glowing brine pool filled with brackish water infused with its vital fluids and psionic energy.
An elder brain's ambitions are always tempered by its relative immobility. Although its telepathic senses can reach for miles, moving anywhere is always a dangerous proposition. If forced outside its brine pool, an elder brain swiftly expires, and transporting an elder brain in its pool through confining and tortuous subterranean tunnels frequently proves difficult or impossible.
Rasgos
Creature Sense
The elder brain is aware of creatures within 5 miles of it that have an Intelligence score of 4 or higher. It knows the distance and direction to each creature, as well as each one's Intelligence score, but can't sense anything else about it. A creature protected by a mind blank spell, a nondetection spell, or similar magic can't be perceived in this manner.
Legendary Resistance (3/Day)
If the elder brain fails a saving throw, it can choose to succeed instead.
Magic Resistance
The elder brain has advantage on saving throws against spells and other magical effects.
Telepathic Hub
The elder brain can use its telepathy to initiate and maintain telepathic conversations with up to ten creatures at a time. The elder brain can let those creatures telepathically hear each other while connected in this way.

Acciones Bonus
Psychic Link
The elder brain targets one incapacitated creature it senses with its Creature Sense trait and establishes a psychic link with the target. Until the link ends, the elder brain can perceive everything the target senses. The target becomes aware that something is linked to its mind once it is no longer incapacitated, and the elder brain can terminate the link at any time (no action required). The target can use an action on its turn to attempt to break the link, doing so with a successful DC 18 Charisma saving throw. On a successful save, the target takes 10 (3d6) psychic damage. The link also ends if the target and the elder brain are more than 5 miles apart. The elder brain can form psychic links with up to ten creatures at a time.
Sense Thoughts
The elder brain targets a creature with which it has a psychic link. The elder brain gains insight into the target's emotional state and foremost thoughts (including worries, loves, and hates).
