This appears as a miniscule marble sized ball of swirling clouds around a tiny fleck of red Eberron Dragonshard. Invented by an aspiring House Cannith artificer, to be used as mostly non-lethal riot control measures for the Sharn Watch.
This marble is designed to be thrown, or used as a sling bullet. If thrown it has a range increment of 20 feet. When the marble strikes the ground it explodes violently outwards in a 15 foot radius. This has two seperate effects;
1) Everyone in the area of the blast is subject to a Bull Rush attempt, having to beat a DC 15 to avoid being pushed backed 5 feet. If pushed into a wall, the target takes 1d6 non-lethal damage. This is particularly dangerous in Sharn, where creatures could potentially be pushed off a bridge, balcony or tower and plummet to their death.
2) If there is any debris laying around it is violently expelled from the area. The spray of items creates a burst with a 15-foot radius. If the items are fairly hard or sharp (such as stones, sling bullets, coins, or the like), creatures in the burst take 1d8 points of damage. Eggs, fruit, and other soft objects can be used, but the damage then dealt is nonlethal damage.
A successful Reflex save of DC 15 negates this damage.
