Tactics

The grievant opens with Petrichor Burst if it can catch two or more creatures, then uses Rain-Slick Grasp to pull isolated targets into the reach of its Stone Fists. It uses Not Yet to remain beside anyone attempting to flee or reach an ally, and in its lair it relies on The Path Bends Back to divide the party. When badly wounded, it fights recklessly to keep one creature close, but flees into cracks or storm drains if no one has spoken to it or acknowledged its grievance.

DM Tips

• Telegraph danger with the smell of rain in a completely dry passage, fresh puddles forming uphill, and footsteps that echo from rooms the party has already left.
• Roleplay the grievant as wounded rather than openly furious: it repeats the last words spoken by departing creatures and pauses expectantly whenever someone says 'goodbye.'
• For a weaker party, remove the thunder damage from Stone Fist and reduce Petrichor Burst to 2d6; for a stronger party, let The Path Bends Back affect two creatures on a failed save.
• Make the lair physically rearrange between scenes, but preserve meaningful landmarks so the maze feels emotionally spiteful rather than random.

Loot

• Rain-Black Heartstone — A warm, fist-sized stone found where the grievant dissolves. It smells of rain and can keep a small campfire burning through one night of heavy weather.
• Bellweather Waystone — A flat stone marked with a half-erased road sign. Once per day, placing it on the ground points toward the last place its bearer genuinely said farewell.
