Dark elves gain a +2 bonus to either Dexterity or Charisma.
Adventurer Tier Elf Feat (Heritage of the Sword): If you can already use swords that deal d6 and d8 damage without attack penalties, you gain a +2 damage bonus with them. (This bonus doesn’t increase miss damage.) Otherwise, if your class would ordinarily have an attack penalty with such swords, you can now use them without penalties.
Cruel (Racial Power)
Once per battle, deal ongoing damage to a target you hit with a natural even attack roll as a free action. The ongoing damage equals 5 times your level. (For example, at 3rd level you would deal 15 ongoing damage against a single target.) As usual, a normal save (11+) ends the damage. A critical hit doesn’t double this ongoing damage.
Champion Feat Once per day, you can instead use cruel to deal 5 ongoing damage per level against an enemy you miss or that you roll a natural odd attack against.
