Copper Dragon Lairs Categoría: lair
Copper dragons typically inhabit multichamber caves and renovated ruins. The region containing an adult or ancient copper dragon's lair is changed by its presence, creating the following effects:
Chatty Critters: Tiny Beasts magically gain the ability to speak and understand Draconic while within 6 miles of the lair.
Giggle Fits: Whenever a creature other than the dragon and its allies is within 1 mile of the lair and rolls a 1 on a D20 Test, it must succeed on a DC 15 Wisdom saving throw or have the Incapacitated condition until the end of its next turn, as it is wracked with laughter.
If the dragon dies or moves its lair elsewhere, these effects end immediately.
Spells
Detect Magic [5.5e], Mind Spike [5.5e], Minor Illusion [5.5e], Shapechange [5.5e], Greater Restoration [5.5e], Major Image [5.5e], Project Image [5.5e]

description
Relentlessly friendly and curious, most copper dragons view the world as a place of endless wonder and possibility. These gregarious dragons are fonts of patience, hospitality, and humor, and they seek to improve the lives—or, at least, the mood—of those they interact with. If forced to fight to defend themselves or their friends, these dragons favor using their slowing breath and physical attacks to subdue antagonists. Only in cases of extreme peril or emotion do they use their deadly acid breath. Copper dragons typically live in caverns amid picturesque hills and rock formations—particularly those that are prominent landmarks. These dragons collect gifts, though they have little interest in treasure without meaning, no matter how valuable it is. To them, thoughtfully given presents and the feelings or memories they symbolize are more important than masterpieces or magical relics.
Ancient copper dragons use warmth and reliability to effect change over time. They open their cozy lairs to their friends as havens of learning and laughter for the young and those in need. These dragons watch for and oppose future threats while fostering sanctuaries of simple goodness.
