Elemental combinations

What is your favorite way to take advantage of the elements?

I prefere using the Basilisk Fire Sniper and combine it with the Dynamo Lightning Ring, so if i land a hit, most of the time with a dash right after the enemys are almost one shot because of the Fire/Lighning combo.

I also thought about trying out the Decay/Earth element, maybe combined with fire, but i cant find some good combinations wich fit my playstyle.

What are you guys playing, and is there any OP combination?
