Changes

You transform your eldritch blast into a binding blast. Any creature struck by a binding blast must succeed on a Fort save or be paralyzed for 1 round plus a number of extra rounds equal to the warlock's charisma modifier. The target becomes paralyzed and freezes in place. It is aware and breathes normally but cannot take any actions, even speech. Each round on its turn, the subject may attempt a new saving throw to end the effect but at a cumulative -1 penalty. (This is a full-round action that does not provoke attacks of opportunity.) Note that dragons are not immune to this effect but get a 34+ to their save and do not suffer a penalty. On a successful save the target is slowed for one round.
