D&D5E: Land of the Sleeping King
The War Petals of the Wrath Bud
The War Petals of the Wrath Bud is an ancient primordial devicecreated by the elves in the Freedom Wars in response to the DragonCurse. Its effects are to bring about the wrath of nature, but its effects are slow to manifest: the very stones slowly awaken, and the great trees uproot themselves and rivers leave their binding shores, all to bring violence to those that have corrupted the land. Everything around it slowly becomes more and more violent. Crushing the petals releases all that pent up aggression at once, summoning a single use primordial army out of whatever nature is around.
