Roger Zelazny book question

Cafe Society

I’ve got a 1981 fantasy book by Roger Zelazny called ‘The Changing Land’.
It features an Elvish magician called Dilvish, who has got a history of dramatic events with other sorcerors.

Does anyone know of another book with the same character?

(Ta muchly in advance!)

Try Dilvish the Damned. Good stuff.
