Deathsong (1-2 slots)
A character must be at least 6th-level to learn this style. This potent weapon proficiency allows a drow warrior who spends 1 slot to gain double damage (target gets a saving throw vs. Death to avoid this increased damage) on every attack that hits by 5 or more than what the drow needed to hit his target. This can further be increased by devoting a second weapon slot to this style.
A drow can also spend a second slot in this style once he reaches at least 9th-level. With 2 slots devoted, the drow causes double damage with a chosen weapon every time he strikes his target by 5 or more than he needed to hit (no saving throw).
Thus a 6th-level drow warrior attacks an orc in chain mail, and rolls a 15 to hit. He then causes the orc to roll a saving throw to avoid double damage, because he hit it by 5 or more than he needed to successfully strike the creature. If the drow was 9th-level and had 2 slots devoted to deathsong, then the orc would suffer double damage automatically, without a saving throw.
