I just recently made another post about this - Clauneck is very good at showing you what in your life does not serve you. This could be a bad habit, a bad relationship, or a bad work opportunity. He helps you to cut out the crap in your life so that you can manifest something even greater.
Claunech is also able to bring you cash from unexpected places. I performed a ritual for this purpose, calling upon Claunech for three days. I received an amount that was higher than I expected, but not outrageously so. It can work to name a specific number, and another approach is to consider how you will spend the money (food, bills, clothes, books, travel, whatever). A combination of both is best, I think.
If you want a good ritual for calling Claunech, check out Wealth Magick by Damon Brand. The book contains a complete system for manifesting a new lifestyle of greater wealth, and the seventh working calls upon Claunech. It has a short mental exercise you perform prior to calling him, and an incantation from the grimoire he is sourced from.
The instructions in the book state to work through the system from start to finish, but you can also work with any of the spirits in the book for a more immediate goal if you wish. The book is worth working through if you want to make extreme changes in your life that can lead you to wealth, but you would likely benefit from doing a little internal work first, to ensure that you are open to receiving a new wealthy life.
