Dagon's Icy Grip (3.5e Invocation)

 ''The terror of the truths known by Dagon can freeze the blood of even the most powerful creature. With your power, you can fill your enemies' minds with horror as you fill their limbs with ice.''

If applied, this invocation causes anyone dealt damage by your abyssal blast (regardless of the option chosen) to make a Will save or become paralyzed. At the beginning of each affected creature's turn, that creature can attempt a new save, at the original DC, to end the effect for itself only.
