5,000 Bosses

Achievement is rewarded after killing 5,000 World Bosses. Despite the description any named bosses (like BAMs subject to quests) do not increase the counter for achievement.

Tactics
There are few guides for this achievement. General tactics involve farming few bosses that have minions with them, which all award a kill for achievement.

Killing Jurzeniir in Tenebrous Mines, Bardragul in Pirate Grotto, Kestol in Tempest Reach and OZ-MND1A5 in Colossal Ruins on 4 channels gives 120+ kills per round. These bosses have 1 hour or 4 hour respawn times. This requires premium account that gives possibility to save few teleport locations. For faster completion it's possible to farm Hyena Tyrants and Kurata near Camp Marrakeen or Sharazan in Spring Valley. With these it's possible to complete 250 boss kills in hour.
