@JeremyECrawford Do young dragons and wyrmlings have lair actions or regional effects?

Lair actions and regional effects belong to legendary creatures that spend a lot of time in their lairs. For more information, see "A Legendary Creature's Lair" in the "Monster Manual" (p. 11). Young dragons and wyrmlings aren't legendary creatures. #DnD https://t.co/UuXnY3vCXg
