A water-aspected Casket of Firedust Conversion inlaid with black jade in curling, frothing patterns resembling the ocean’s waves, that turns firedust into waterdust.
A firewand with waterdust in it fires a flood of faintly blue-green Essence. The target, if hit, feels her lungs begin to fill with water. She immediately takes 6 dice of bashing damage, soakable only with Stamina, and makes a Stamina + Resistance roll, difficulty 3. If she succeeds at this roll, then she takes a -3 penalty to all her actions for the rest of the round; if she has already acted, then this penalty carries over to the next round. If she fails the roll, then she is unable to act for the rest of the round; if she has already acted, then she is unable to act in the next round.
The flood of blue-green Essence fires from the firewand, and then spreads liquidly, as if puddling. Everyone within this “puddle”, which has a radius of about 10 yards, suffers the same effect as the single target of an uncommitted charge of waterdust (see above). The person who fired the firewand is not immune to this effect, should he be within the area of the “puddle”.
