Lair and Lair Actions
Yasdamura’s Lair
Yasdamura lives in a desolate volcanic island and is usually found sleeping in a cave or wandering the island in search of food. The island is mostly charred black stone and dried lava, with extreme heat and the smell of burning flesh and sulfur in the air.
Lair Actions
On initiative count 20 (losing initiative ties), Yasdamura takes a lair action to cause one of the following effects; Yasdamura can’t use the same effect two rounds in a row:
- Magma erupts from a point on the ground Yasdamura can see within 120 feet of her, creating a 20-foot-high, 5-foot-radius geyser. Each creature in the geyser’s area must make a DC 15 Dexterity saving throw, taking 21 (6d6) fire damage on a failed save, or half as much damage on a successful one.
- A tremor shakes the lair in a 60-foot radius around Yasdamura. Each creature other than Yasdamura on the ground in that area must succeed on a DC 15 Dexterity saving throw or be knocked prone.
- Volcanic gases form a cloud in a 20-foot-radius sphere centered on a point Yasdamura can see within 120 feet of her. The sphere spreads around corners, and its area is lightly obscured. It lasts until initiative count 20 on the next round. Each creature that starts its turn in the cloud must succeed on a DC 13 Constitution saving throw or be poisoned until the end of its turn. While poisoned in this way, a creature is incapacitated.
Regional Effects
The region containing a Yasdamura’s lair is warped by the elemntal’s magic, which creates one or more of the following effects:
- Small earthquakes are common within 6 miles of the dragon’s lair.
- Water sources within 1 mile of the lair are supernaturally warm and tainted by sulfur.
- Rocky fissures within 1 mile of Yasdamura’s lair form portals to the Elemental Plane of Fire, allowing creatures of elemental fire into the world to dwell nearby.
If Yasdamura dies, these effects fade over the course of 1d10 days.
