What is the most interesting/unique build/class you've ever done?

The "Bronze Sentinel" build. It was the first time I followed a set build and it was interesting. It was alot of fun.

A compassionate and surprisingly honor-bound Khajiit vampire illusionist/assassin.

That makes me wish I could get an aetherium one handed sword to go with the shield.
