Liquidation

You attempt to slam a full-force blast of water into a target in range.  Make a ranged attack, doing 2d6 + MOVE water damage on a hit.  If the natural attack roll is 18 or more, the target’s AC is reduced by 1 while it remains in battle. This decrease may be stacked up to a maximum of -5 to AC.

At Higher Levels: The damage dice roll for this move changes to 2d8 at level 5, 4d6 at level 10, and 6d6 at level 17.
