The Alliance Slayer
With a bounty on your head while within War Mode, get 10 honorable kills without dying.
The Alliance Slayer is an achievement earned by getting 10 honorable kills without dying while you have a bounty on your head in War Mode.
Enable War Mode
Enable War Mode before heading out. Take the boat to the opposing faction's territory to begin working toward your bounty.
Farm Kills for Bounty
Kill enemy players in a raid group — Drustvar is a confirmed zone where this works — until the bounty quest is pushed to you, which can take 30 or more kills.
Leave Raid Group
Once the bounty is on your head, leave the raid group, as kill progress toward the achievement only counts outside of raid groups. A party of up to 5 players still works.
Group Up and Defend
Form a 5-man group with at least one healer and high-mobility classes, then target solo players or small groups in Drustvar to safely reach 10 honorable kills without dying.
Use Safe Travel Tools
To reposition without losing the bounty, you may use a 
Flight Master's Whistle, a Mage portal to Zuldazar or Kul Tiras, or a Hearthstone set to an inn in Zuldazar or Kul Tiras — portals to old zones such as Orgrimmar will cause you to lose the bounty debuff.
Tips
Disconnecting while the bounty quest is active will cause it to fail, so farm in a stable network environment.
Staying near water and bringing a healer to defend you are confirmed ways to survive while the bounty is active.
The title awarded alongside this achievement is a quest reward, not the achievement itself — faction-transferring the character will permanently remove the title with no recovery.
