Boar Training: Thundercall

To get to Thundercall, take the road up the cliffs at 80.88, 31.42, follow this path until you are on top the mountain at 82.07, 29.37, jump down and when you are at 83.78, 29.92 you jump over the small gap to the next mountain, where you see 2 Windrocs.

When you have done that you simply follow the path until you are at 90.70, 24.71.

This guy is hard to get to:

Start at The Ring of Trials flight path in Nagrand (79:49). To the Northeast there is a little horde city, Wor'var; Go around it, to the left, and you'll see a little path up the side of the hill. Go up it (82:41).

When you get to the pond with the Young Meadowstompers (84:40), turn left. Go between the cliff and the pond. At the top of the waterfall, cross the stream and keep going straight.

You will soon come to a place where you can go up (right) or down (left) (84:35). Go up. It curves to the right. Follow it until you get to a rock overpass/bridge (86:38). DON'T go over it.

Turn left. Stay close to the edge of the cliff (on the right) and you will come to a downward path. Go down. Follow that brown path along the rock wall (to your left) until the wall is gone (89:33).

Take the left turn in the path. It immediately disappears but keep going. Shortly, you will find a tiny path to your right. Make a U turn to go down (there is a cave at the bottom, don't go in).

From here (88:32) you hug the cliff on your right and just keep going. Thundercall is at the end.

(Edited, thanks Karuuti)
