Lesharr's Entrapment (3.5e Invocation)

''Lesharr, Lord of Bindings, The Jailer of the Abyss. None know a more terrifying figure, for none escape his clutches. The energies you wield bind others in the same way, stopping them impeding you.''

If applied, this invocation causes anyone dealt damage by your abyssal blast (regardless of the option chosen) to make a Reflex save or become immobilized and uncentred. At the beginning of each affected creature's turn, that creature can attempt a new save, at the original DC -4, to end the condition for itself only.
