Off the top of my head, I can't think of any ranged slot clicky items with beneficial stats for a Shaman at least from common sources.
Shaman usually go for a standard spyglass, or the kromzek spyglass (both can be clicked from inventory rather than in an item slot), or a skull earring from grachnist (like 1.8K? something like that), or the free star of eyes quest item.

If you're willing to use an inventory slot for canni-clicking, there's 3 cheap options ready to go.
