Rain of Ore CR 5
Type natural (the natural effects of alligotonium); Perception DC 10 (automatic); Disable Device —
Trigger already triggered once noticed (explosion at Demon Pass); Reset none
The rain of ore appears as a cloud of swirling and floating metallic debris that sparkles as bits of alligotonium ore reflect any available light source.
The material freely floats, directed by natural wind currents until the weightlessness effect of the agitated alligotonium ends.
The source of the rain of ore is the blasting site at Demon Pass; the workers unintentionally exploded a massive vein of alligotonium, agitating the magic material causing it to become lighter than air. Driven by prevailing winds, the ore cloud drifts over Steamtown.
Effect The weightless effect of the floating cloud of alligotonium disperses when it reaches the area above Steamtown. The chunks of heavy, jagged metal rain down upon the area, including the helpless tent city. Those caught without ample protection suffer bludgeoning damage (DC 20 Reflex for half damage).
The extent of damage a creature suffers as a result of the rain of ore depends on the size of chunks that fall upon them. Use the following chart to determine the proper level of damage caused by the trap.
1-25 Several Small-sized bits (3d4 damage)
26-50 Several Medium-sized pieces (6d4 damage)
51-75 A few Large-sized chunks (6d6 damage)
76-99 Several Large-size pieces (6d10 damage)
100 An enormous Huge-sized chunk (10d10 damage)
Any substantial, solid structure negate damage done by the falling ore, but there is a chance that the damage done irrevocably damages any built structures it falls upon. Use the damage determination chart above to discern how much damage is done to any particular structure. If the damage results in more than ¾ of the structures durability, it collapses upon those inside causing damage to creatures equal to ¼ of the damage done to the structure itself.
