No Rest for the Wicked - Echo Knight 3m25s (No food heals, Rapier build)
The key points for the build :
Life leech on weapon or ring, or on two rings. Or, if you are lucky, go for life leech weapon + 2 rings for insane life regen. For the third ring, I like the one that reduces your attacks' stamina consumption, but if you have a 4% stamina regen glove you could probably slot another ring.
Gloves with at least 3% stamina regen. 4% is even better, but harder to get.
Investment in equipment load so that you can have a heavy armor rating while still being able to dodge-roll you way out. I invested a tad too much but since we can't respec, it'll stay as-is.
Gear with extra stamina and healing effects affixes. Cursed gear is fine (and preferred) with anything that's EXP related (because XP loss doesn't matter when you've hit the level cap).
Rapier's really fun, in that there is no downtime between attack streaks : It's slower than a more nimble weapon but very consistent in its attack timing, making it a very nice weapon to use. And it moves you forward as well, which is great for opponents that tend to move around a bit, like the Echo Knight.
