The top and right entrances are the ones you really have to worry about, as initially they're protected by only a single spirit tower each. These towers probably won't last long, and you'll need more. Four or five towers placed along the edge of each entrance is a good idea, as the attackers will be occupied with them long enough for you to move over and take them out. You can buy WoTLK Gold also place an acolyte or two behind each row of towers and set their repair ability to auto-cast to make the towers last longer.

It may look silly, but this is an effective defense against intruders.

The right entrance will mostly see knights, sorceresses, priests, and mortar teams. Since these are all ground forces, one effective method against them is to use goblin land mines, and you're in luck because 12 of WOW WoTLK Classic Gold them have been provided for you. Take Arthas over to the west to collect the mines when you get a breather in between attacks, and then place them on the right near heavily trafficked areas.

These will take out quite a few of the attackers before they can even reach your towers. The top temple entrance is more often visited by steam Warcraft, gryphons, knights, and an occasional archmage. Since so many flying units come through here, you should keep a healthy supply of gargoyles and crypt fiends (with their web ability set to auto-cast) in this area. You can run your forces back and forth, but it will be easier if you leave an even number of troops at buy WoTLK Gold each of the three sides.

A few minutes into the mission, the burning legion will start to reinforce your troops with their own. For a while, you'll get groups of three felhounds at periodic intervals, and they will strengthen your melee effort considerably. Close to the end, you'll also get a group of infernals, which are huge fiery golems with massive supplies of hit points and attack power. Try to keep these extra units alive, because you'll need absolutely everything you can throw at the enemy in the last two minutes or so of the mission. The attacks are fairly regular and of average intensity throughout most of the mission's 30 minutes, but in the last 90 seconds, you'll be blitzed on all sides by a massive attack.

Arthas will make an announcement when this assault begins, so be ready. It's imperative that you get as close to the 90 supply limit as you can and have as many towers blocking the entranceways as possible. If the entrances are left open, the human units will pour into the temple at an unstoppable rate and start flaying Kel'Thuzad. All you have to do is keep them out for about a minute. If enemies do get inside, Arthas' death coil is very effective at These towers probably won't last long, and you'll need moreThese towers probably won't last long, and you'll need morehealing Kel'Thuzad, although you may not be able to keep up with the attack rate. When the timer finally hits zero, you've won the mission.
