Or you could create an alternate version of the ritual that's lower level, but requires some sort of sacrifice on the part of the players or otherwise exposes them to problems.
A version of the ritual that requires a small animal being sacrificed for instance. Or that lights up a giant pillar of energy that is visible for miles upon completion.
Or a version that draws on the power of vecna by causing something about them to become secret a-la iron council (although that's really more appropriate for a more powerful but technically one-off ritual like consult mystic sages or the like).
