RPG Superstar, Season 9 submission---post edits to prevent DQ, and some helpful suggestions:
Sphere of Raging Waters Aura moderate conjuration; CL 7th
Slot none; Price 9,000 gp; Weight 4 lbs
The depths of this dark blue sphere seem to sink into a bottomless watery oblivion as its surface roils in endless turbulence. The bearer of the sphere can release these waters on command—emptying the waters of the sphere in a raging flood as flowing water (Core Rulebook, 432) in a direction of their choosing, completely flooding up to twelve 5-foot squares with water.
By manipulating the sphere, rotating it in one direction or another as a square fills, the user determines the current’s direction in that square, and can adjust the square’s flow rate from 10 to 90 feet per round. At the beginning of their next turn however the waters surge back into the sphere, dragging any trapped creatures with them on a successful drag check (using the bearer’s CMB) until the waters are again released. Dragging a creature through the water does not provoke any attacks of opportunity.
Trapped creatures can swim free of the sphere with a successful DC 20 swim check; landing in a square of their choosing adjacent to or near the sphere holder. If the sphere is emptied while a creature is trapped within, this creature is released at the forefront of the flood, moving through the turbid waters to the farthest available flood square.
Construction Requirements Craft Wondrous Item, Control Water; Cost 4,500 gp
