This next challenge is fascinating

When you reach The next World of Warcraft Season of Discovery settlement, you'll have the option of continuing to the west towards the high ridge, and strike the three towers of spirit from above using the mortar team. If you continue to the west, you'll see some skulls that can give you the goblin night scope which will enhance the night vision. Return to WoW Classic SoD Gold eastwards and then head towards into the World of Warcraft Season of Discovery. When you've reached your first vessel, attack it with your Ice trolls. The most efficient method however is to use Muradin's lightning bolt. One strike from his attack will cause the ship to sink. When you come across one of five of Warcraft Storm bolt it and then proceed to the next.

When you keep going you'll come across some very strong nerubian monsters. Make use of your fighting skills to take on them and be careful not to take more than a few losses. When you next attend a camp for mercenaries, you will be able to avail the services of an Ogre magi, who can cast bloodlust, as well as Ice troll berserkers that are more powerful than standard trolls. You can fight your way through merlocs before heading to the point where trees block your way. If your mortar squads are active, you can ask them take on the trees in order to take them down. In other cases, go to the top of the hill, get goblin sappers and make them explode on these trees in order to make path. In the next mercenary camp you can get Ogre maulers, troll high priests and trappers for trolls. The latter two are available in relation to your gold and troop reserves, however, you must hire at least one trapper in order to help against the blue dragons ahead. A trapper is able to use a net to catch the flying unit, which will bring it to the ground, opening it up for melee attacks.

Make use of Arthas the magical shield to help him get through the maze.

This next challenge is fascinating and can be easily overcome. The spirit towers are lined up along up the walls of the canyon and they'll annihilate your troops should they attempt to WoW SoD Gold pass through. The solution is to buy an amulet of recall from the goblin shop and present the item to Arthas. Switch on his shield of divine power to make his invincible. Then, move his way until he reaches the exit. Once he's in the area, you can make use of the amulet to bring 12 of your troops to the spot where they are. It's time to let go of any units that can't succeed, since they'll be killed attempting to cross the canyon.
