Sith Marauder

Prowess
Hatred-Whenever an opponent loses life from a source other than combat damage, Sith Marauder gains double strike until end of turn.
"Is it battle that stirs you, to meet an enemy blade upon blade? Such is the way of the greatest of the Sith Marauders, who seek strength in war... and in rage."
Darth Traya, Lady of Betrayal
