Most melee kills in one turn?

[velk]

You could probably up that kill rate tremendously by using area affect weapons like sunslayer, sword of many colors, stone sword, demon whip, harvest blade etc.

Natajara with heroic quickness wielding harvest blade, stone sword and unquenched sword would be interesting. You would probably end up swatting yourself sooner or later with the stone sword though, perhaps ember would be a better choice.
