Ascendancy class for Glacial Cascade build.

Any tips on what ascendancy class to choose for Glacial Cascade build? The last time I played PoE was before Ascendancy so I'm not sure how it works and what would fit the skill the best.

I've made some mockup builds for Shadow, Witch, Templar, and Scion, which are all basically standard elemental/cold-based spell builds.

Inquisitor.

Assassin

Occultist (Elementalist also works)

Scion

Keep in mind the builds aren't 100% optimized. The Assassin build is the most complete since I'm more comfortable with that side of the tree.

[e] Assassin build updated because of some poor passive choices that I didn't see first pass (don't need as much HP for instance). Iron Reflexes is optional and dependant on your gear.
