Stone of Shielding

Stone of Shielding

Property:  This single-use item is a spherical white stone about an inch in diameter. Whenever crushed, it activates its power, and can thus be unintentionally activated by a fall or attack. A stone of shielding causes a sparkling,  inking aura to spring into being around the creature who crushed it. This aura lasts for three rounds, boosting  he armor class of the affected being by a +6 bonus on the first round, a +3 on the second round, and +1 on  the third round, during which it flickers before finally winking out. Therefore, a mage of AC 12 crushes a stone  of shielding and gains an armor class of 18 the next round. This reduces to AC 15 at the end of the following round, and AC 13 after that.  This item stacks with other effects, like magic armor, rings, and spells.
