Monsters with regional effects

[Bootlebat]

What would happen if, say, a green and red ancient dragon share a lair? Are the regional effects cumulative?

 

[Rya.Reisender]

Dragons sharing a lair? Preposterous!

(By RAW I'd say yes. Nothing says that regional effects don't stack.)

 

[MechaTarrasque]

Love may be blind, but the neighbors aren't.....I would say both sets of regional effects would be in place.

 

[Satyrn]

I'd love to be their divorce lawyer!

 

[jasper]

I hate love springs. But I would say yes.
