<div class="mw-collapsible-content">Chaos Four enemies have hefty defenses against attacks that cause slow, so be sure to adjust your layout to account for the [[Berserker_Orc|Berserker Orcs]] that will rush out from the ground lanes. They can be stunned, frozen, and launched into the air though, so those are good tactics to stall them. Well placed barricades will also help to keep them from the crystal. Remember that you do not need to defeat any enemies on this map apart from the Demon Lord, so plan accordingly.

This is a stage fight against the boss - Demon Lord. Each wave will spawn infinite enemies until a third of his health has been taken away, on each wave. At the start of a wave, you cannot attack the Demon Lord, but he will attack you. He will ignite you, causing fire damage over time, and this attack hits all heroes and is unavoidable. The Demon Lord will also repeatedly throw lava balls at or near each hero, and do splash damage when they hit. This attack will hurt your towers and the crystal, so be mindful of where you are standing, and be prepared to dodge. The lava balls he throws at you can also snap you out of a jump animation, and can cause you to fall to your death if you are over a lava pool when you are hit by one. Gnash the Flame Lance (large [[Berserker Orc]] miniboss) will often spawn at the beginning of any wave.

In order to damage the Demon Lord, you must first stun him. Once each wave begins, at some point during the wave a Lava Guardian will spawn from any of the ground lanes at random. A white exclamation mark will be shown above the area he will spawn from, but will vanish once he actually spawns, and no icon showing their location will exist after that. These units will spawn repeatedly over time, but are spaced out in frequency. Upon defeating a Lava Guardian, it will drop a lava ball on the ground. This is a Hero debuff that you can acquire by having your hero touch it. Once you touch a lava ball, it will vanish and you will see a lava ball debuff icon on your screen, and the hero will have a red glow to them. There is no timer on this debuff, and you can only carry one lava ball debuff at a time. More than one lava ball can be on the ground at one time. If you swap heroes once you have the debuff or die, you will lose it and need to get another lava ball. The lava balls the Demon Lord throws do not end up as debuffs on the ground in any way.

Once you have the debuff, return to the area where your hero spawned when the map started and where you spawn when your hero dies. In that room, there is a hallway on the side that leads up some stairs to a long rampart that oversees most of the map. On that rampart you will see a catapult. If you approach the catapult while you have the lava ball debuff, the debuff will be removed from you and a lava ball will then become loaded onto the catapult for use. When the catapult is loaded with the lava ball and the debuff is removed, all other existing lava balls on the map or held by other heroes are also removed at that time. Before you use the loaded catapult, jump onto it. You cannot stand on the actual lava ball, but you can stand on the catapult where the ball is, and the graphics will just overlap. You can then activate the catapult, which will also launch you with it.

The lava ball will then stun the Demon Lord. When you activate the catapult, a lightning debuff symbol will appear on the screen for 20 seconds, representing the total time the Demon Lord is stunned for. However, he must first fall down in range to be hit, and you cannot do any damage to him until his health bar shows up on the top of the screen. The actual time you have to damage him once he is in range is about 13 seconds. This is why you want to stand on the catapult, as it will launch you at the Demon Lord, and put you quickly within range. When you get launched, you can move your hero in mid-air. Try to land to the left of the Demon lord, near the Western double spawn point, so that you do not land on any lava patches and die. The Demon Lord will always fall over in the same location, and he can be damaged the Hero as well as by any defenses you build that are within range. Once the debuff timer is up, the Demon Lord will rise up again, and you will need to get another lava ball and stun him again. This process will continue until you lower his health by a total of one third of his total health. Once you lower his health by that much, that wave will end. When the wave ends, all lava balls and debuffs will be removed. On Wave 2, repeat the exact same process until you lower his health by another third, to end that wave. On Wave 3, you must then get his health to zero to end the wave and win the stage.</div>
