Delirium of Demogorgon (3.5e Invocation)

Aameul and Hethradiah don't behave according to the laws of reason, and through their power, you can will the Material Plane, as the child of the Abyss, to do the same.

If applied, this invocation causes anything dealt damage by your abyssal blast (regardless of the option chosen) to make a Fort save or become affected as if by a reverse gravity spell. 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. For objects, there is a flat 10% chance that the effect ends.
