Binding Stone (3.5e Equipment)
From D&D Wiki
Binding Stone: This stone is 2 inches across and polished an intricate obsidian black, patterned with swirling energies just below the surface. When thrown at an enemy and activated by command, the stone attempts to suck the target in and trap it within itself, as if per the Minimus Containment variant of the binding spell. In order for this process to take effect, you must succeed on a ranged touch attack against the target. Creatures with 7 HD or less get no save against this effect, but creatures with 8 or more HD may attempt a DC 21 Will saving throw to resist the stone's effect. Regardless of success, the stone becomes inert after its power is called upon. After the stone has successfully sucked in a creature, it is bound within the stone indefinitely, until it is shattered. A binding stone has hardness 10 and 5 hit points.
