Multiclass ideas for Tempest domain cleric

I really love the tempest domain cleric’s channel divinity being able to maximize lightning and thunder damage rolls. What are some fun or unqiue builds that can utilize this? They don’t have to be OP or the BIS multiclass i just like hearing what other people have come up with

Right now i really want to multiclass it with the new storm herald barbarian and use the sea storm aura and channel divinity together (i know this isn’t the best but i think it’s rad and flavors well together)

So what other cool builds can you guys come up with?

Note: This can be for 5 or 5.5 editions
