These dense pebbles are sometimes used by drow skirmishers for both offense and defense.
When a stalagmite seed strikes a natural stone surface, a stone stalagmite immediately emerges where it landed, filling the 5-foot square and growing to 10 feet in height. Any creature occupying the square takes 5d6 points of piercing and bludgeoning damage and is knocked prone. Any creature that succeeds at a DC 14 Reflex save takes half damage and is not knocked prone.
