Rune-Bound Blast-Stone
An expertly crafted obsidian stone is embedded into a stone pillar or wall. Its surface is etched with delicate, subtle Norse-style runes that represent fire and consumption. The stone remains cold until approached, at which point the carvings begin to pulse with a low, eerie orange light.

Defenses
Detection
“A polished black stone roughly the size of a human heart, recessed into worked stone. Around its edges, fine silver wire is inlaid into the rock in circular knotwork patterns. When triggered, the runes glow like molten metal, casting long, sharp shadows through the dim, smoky air of the dungeon.”
Standard Engagement
A creature enters a 15-foot radius of the stone while the stone is active.
None
The stone absorbs ambient heat and resets itself after 1 hour.
When triggered, the stone releases a sudden, violent sphere of fire. All creatures in a 20-foot burst take 6d6 fire damage. A creature that succeeds at a DC 21 Reflex save takes half damage (or no damage on a critical success).
A character who has the Shield Block reaction or is currently Raising a Shield gains a +2 circumstance bonus to their Reflex save as they dive for cover behind their equipment.
In dim light or darkness, the DC to notice the hazard with Perception is reduced by 2 due to the faint orange glow of the charging runes.
