The Frightened Kodo NPC will spawn in southern part of Darkshore on the four spawn points seen below:
/way Darkshore 41.31, 65.48 Frightened Kodo /way Darkshore 44.04, 67.56 Frightened Kodo /way Darkshore 41.27, 54.01 Frightened Kodo /way Darkshore 38, 66 Frightened Kodo /way Darkshore 39.20, 56.50 Frightened Kodo /way Darkshore 44, 65 Frightened Kodo
The respawn timer is reported to be between 2 hours and 9 hours, so be prepared for a long wait before finding it. Most estimates have placed the respawn timer at around 6 hours. It seems to spawn pretty much instantly after the server resets, so it might be a good idea to check for it just after a server restart.
To notice when it spawns, use your favorite rare spawn add-on, or just spam a macro with "/tar Frightened Kodo" every few minutes. I think it's much better to use an add-on tough, because then you will be instantly notified when it spawns.
Some small tips for making your farming of the Frightened Kodo a bit easier:- It can be obtained by any character that is able to click on it, even level 1 character. However, you need to be level 20 to use it, so you could potentially make a level 20 Allied Race character to use as a scout. It would be even better with a level 110 Class Trail Character tough, since these know how to fly.
- Anyone can click on the Frightened Kodo, even when the opposing faction controls Darkshore. So it does not really matter if you play Alliance or Horde, and you both have to share the rare spawn.
