A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.
Trigger Liralarue fails a saving throw or attack roll
Effect Liralarue rerolls the saving throw or attack roll that triggered this reaction. She then experiences confusing visions of multiple futures all at once and becomes Stupefied 1 until the end of her next turn.
Living Dream
Liralarue is made from solid dream-stuff. She no longer needs to sleep, breathe, eat, or drink. In return, she can't further develop her powers or exist outside the Dimension of Dreams—if she's forced out of the Dreamlands, she vanishes, then reappears 1 year later in the Dreamlands. She can be killed normally, but barring such an event, she could live forever as she no longer ages.
When Liralarue casts the following spells on a PC or an item they carry while they're visiting her in dream, the lasting effects and results of that spell persist into the waking world: Dispel Magic, Hidden Mind, Remake, and Retrocognition.
