What signs outside in nature and in synchronicities do i have to look out for when working with amdusias?

Basically Ive been wanting to work with amdusias for a very long time since i have been interested in goetic Magick for a long time but can you guys tell me a list of some telltale signs that amdusias is calling out to me? Im really hoping to establish a connection with him and get alot of results in my work
