Description
Red dragons take whatever they desire and burn to ash anything that stands in their way. These chromatic dragons endlessly desire more—more magic, territory, treasure, or whatever else inflames their cruel ambitions.
Lair and Lair Actions
Blue Dragon Lairs
Blue dragons dwell in arid lands. Their lairs might be death traps meant to entomb invaders or ostentatious fortresses where they plot domination.
The region containing an adult or ancient blue dragon’s lair is changed by its presence, creating the following effects:
Sinkholes. Sinkholes form more frequently in the area within 1 mile of the lair. Whenever a creature in that area other than the dragon and its allies finishes a Long Rest, roll 1d20. On a 1, a sinkhole opens beneath the creature, and the creature must succeed on a DC 15 Dexterity saving throw or fall 2d4 × 10 feet into the sinkhole.
Spiteful Storms. Dust devils and thunderstorms rage within 1 mile of the lair. The area is Lightly Obscured.
If the dragon dies or moves its lair elsewhere, these effects end immediately.
