Sphinx

Sphinxes are a race of intelligent, immortal magical beasts. A sphinx guards in sacred isolation the secrets and treasures of the gods. Its great wings sweep along its flanks, its tawny leonine body rippling with muscle and possessed of forepaws powerful enough to tear a humanoid in half.

Androsphinx
An androsphinx bears the head of a humanoid male on its lion's body. Outwardly gruff and downcast, it often begins conversations with insults or negative observations. Beneath this gruff exterior, however, an androsphinx has a noble heart. It has no wish to lie or deceive, but it doesn't give away information readily, choosing its words as wisely as it guards its secrets.

Gynosphinx
A gynosphinx bears the head of a humanoid female. Many have the regal countenances of worldly queens, but some are marked with wild, leonine features. A gynosphinx's eyes see beyond the present time and place, and penetrate veils of invisibility and magic. Supplicants who look deep into those eyes might find themselves magically displaced, banished to some far-flung plane where a difficult trial awaits them.

Abilities
Both androsphinxes and gynosphinxes have the following abilities:

Characteristics:


 * Damage Immunities: Psychic


 * Condition Immunities: Charmed, frightened


 * Inscrutable: The sphinx is immune to any effect that would sense its emotions or read its thoughts, as well as any divination spell that it refuses.

Atacks:


 * Multiattack: The sphinx can make two Claw attacks.

Legendary Actions:


 * Claw attack, Teleport (120 feet), or Cast a Spell

Lair Actions:

On initiative count 20 (losing initiative ties), the sphinxes can take a lair action to alter the flow of time within the lair or teleport themsevles with several other creutures. The sphinx can’t use an effect again until it finishes a short or long rest:


 * Every creature in the lair must reroll initiative. The sphinx can choose not to reroll.
 * Every creature in the lair must succeed on a DC 15 Constitution saving throw or become 1d20 years older or younger (the sphinx’s choice), but never any younger than 1 year old. A Greater restoration spell can restore a creature’s age to normal.
 * Everything within the lair moves up to 10 years forward or backward (sphinx’s choice). Only the sphinx is immediately aware of the time change. A Wish spell can return the caster and up to seven other creatures designated by the caster to their normal time.
 * The sphinx shifts itself and up to seven other creatures it can see within in its lair to another plane of existence. Once outside its lair, the sphinx can’t use lair actions, but it can return to its lair as a bonus action on its turn, taking up to seven creatures with it.
