Gnomesequence I have no idea how to get it to work so I have been trying to create my own

BM hunter 1 button macro.
When farming instead of press a few buttons on the keyboard is it possible just for one?

I've been trying to make a 1 button macro. but I cant get it to work esp when having trouble with multishot it just wont go off in the macro.

Ive tried adding multi-shot, Dire Beast, Bestial wrath and aspect of the wild.

Can anyone create such a macro pls?
