Here are some quick Evil alignment hits that will require minimal effort. When you find yourself stuck trying to choose between whether to aim for an Evil or Chaotic shift in a quest, weigh your options. Will you have more trouble finding Evil hits or Chaotic hits in the long run?
Newport
-Speak to One-Eye Murt in SNP and choose the dialogue option that will take his life. No negative faction or guard aggro will be given. For reasons unknown, you will also receive a book detailing Iksar genitalia.
-Speak to Foridin the High Elf in NNP and agree to sabotage his daughter's romance with the smith's son at the forge. The Evil hit comes at the end of this very short quest. This is only doable during the daytime.
-Speak with Foreman Andrin at the docks and choose [D2], the rude dialogue option. This is a minor Evil hit in itself, though you can follow the quest to completion for further Evil hits or even a Chaotic shift (though the Chaotic path goes hand in hand with a Good hit, too). Foreman Andrin only appears during the daytime.
-Kill the fish at the bottom of Blackburrow and give four (4) Piranha to Voleen the baker and insist that her reward is not enough. (Do so only once or you will receive an unnecessary Newport Citizens faction hit.) She is found in her bakery during the day and frequents the docks by night.
Oggok Mines
-It is imperative that you speak to Keeper Vaj in the far western area of the zone before you do anything else. Upon hailing him, choose the dialogue option that reads, "Why does it matter who they are? If they are in your way, deal with them as you see fit. Valk is whatever you want it to be." This option yields both Evil and Chaotic hits.
-After having done the above, return to the zone entry and speak to Miner Yrenis about his lost pack. Agree to retrieve it from the beast that stole it. Run up the waterfall, hug right, and you'll find the little guy. Hail him and choose the dialogue that reads, "Save your words and die, beast." Loot the pack from his body and return it to Yrenis, saying, "He's food for the worms." (This makes you KoS to the Nilvalk, rendering Keeper Vaj's dialogue inaccessible if you haven't already done it!) It is possible to glean a Chaotic hit from this quest by helping the little guy find food and then lying to Miner Yrenis saying that you killed him, but this would come with a Good hit and would preclude the Evil.
Azzerach, the Forsaken Realm (Plane of Fire)
-From the port-in, use your travel song to fly over/around the enemies and go toward the big island surrounded by lava. When there, avoid aggroing anything and track/speak to "A Wounded Hakim Soldier," who will ask you to fetch him bandages. Rudely decline to help him and you will receive a minor Evil hit.
Anyway, hopefully you've not already done them all! Happy questing.
