Goblin land mines are effective against thickheaded enemies

Soon you'll see WoTLK Classic Gold a brief cinematic during which Tyrande and her allies decide, against Furion's wishes, to free a mysterious being named Illidan somewhere deeper in the dungeon. They'll split off, leaving you with only Furion and some support units. Keep going until you get to a chasm with a circle of power in front of it. Step on the circle to extend a bridge, and then head on, fighting the watchers when you encounter them. To the south is a fountain of mana, and if you have Furion's tranquility spell, now is a good time to use it and replenish your mana quickly.

Head north afterward, fight the dragons, and then you'll finally encounter the druids of the claw. Unfortunately, they'll attack you on sight, so the best option is to use the druid of the talon's cyclone ability to disable them until you move past them. Keep pressing on, fighting the other enemies and neutralizing the druids, until you find the circle of power and switch over to Tyrande's quest.

The gate directly ahead of your starting position here is locked, so head back to where the path splits and go north to step on the circle of power. Now swing back around and go south to step on the circle on this side, opening the gate. Be sure to pick up the archers in the room below the circle here. Go back and then through the main gate. Head into the room with the sleeping guards, take them out, then open the door to the left to enhance your huntresses' weapons. Now go back into the main hall and buy WoTLK Gold continue on.
