• Second Roar: Wisdom Saving Throw: DC 20, each enemy in a 500-foot Emanation originating from the sphinx. Failure: The target has the Paralyzed condition, and it repeats the save at the end of each of its turns, ending the effect on itself on a success. After 1 minute, it succeeds automatically.
• Third Roar: Constitution Saving Throw: DC 20, each enemy in a 500-foot Emanation originating from the sphinx. Failure: 44 (8d10) Thunder damage, and the target has the Prone condition. Success: Half damage only.

Regional effects

The region containing a sphinx of lore's or sphinx of valor's lair is altered by its presence, creating the following effects:

• Distant Sight: While in its lair, the sphinx can cast Clairvoyance, requiring no spell components and using the same spellcasting ability as its Spellcasting action. When cast this way, the spell's range is 1 mile.
• Infusion of Knowledge: Whenever the sphinx or one of its allies takes a Study action while within 1 mile of the lair, it adds 1d6 to any ability check it makes for that action.

If the sphinx dies or moves its lair elsewhere, these effects end immediately.
