Decaract

The Decaract was an event boss accidentally released on August 8, 2017. Like the Pentaract, it was comprised of a ring of towers interconnected by lines of particles. However, the Decaract doubled the number of towers to 10, and a Pentaract Tower Ultra spawned in the center of the setpiece when all are killed.

The Decaract was heavily redesigned and repurposed for Month of the Mad God 2018, where it serves as the final boss of the Mad God Mayhem dungeon.

The Realm Eye says:
Oryx crunched the numbers and figured that if a creation with five towers kills some people, then a creation with ten towers should kill twice as many people. Thus the Decaract was born.
The Mad God’s math was blatantly wrong, but not in the way anyone expected. In fact, his new creation was so unimaginably effective at killing that Oryx was unable to tell what was happening.
He had to deliberately weaken his own murderous masterpiece just so he could decipher what made it so potent in the first place. He has yet to replicate its success.

Behavior

Does not move. Spawns Oryx Eyes at a constant rate while throwing red bombs that slow. When a tower is reduced to 1/2 HP, it will flash red, turn invulnerable for a few seconds, and then start shooting 3-directional bursts of silver shields that stun.

If a Tower has been downed, but not all 10 of them have been killed yet, they will respawn after a short time just like a normal Pentaract Tower.

Trivia

The Realm Eye’s description references the nerf made to the Decaract fairly quickly after its release, due to its extreme potency to nearly instantly kill multiple maxed characters, with the Oryx Eyes’ shots’ high speed, damage, and number.

Tips and Strategies

BE EXTREMELY CAREFUL of the huge numbers of Oryx Eyes that spawn. They can easily tear through even the hardiest of players through a combination of Armor-Piercing and Sickening attacks, so it is imperative to keep moving. Be wary of the central Decaract tower - when it spawns, it will instantly spawn in a huge group of Oryx Eyes.

Puri priests are very valuable here for getting rid of sickens. In addition, piercing or AoE weapons are appreciated for thinning the hordes of Oryx Eyes quickly.

The slowing and stunning shots make soloing the Decaract extremely difficult, and practically impossible on a slower-moving character, or if you have not maxed SPD. A rogue can solo the Decaract easier than most classes, due to the invisibility from cloaking.

In a small group, a frequent tactic to coordinate killing the towers simultaneously is not to do any kill shots until somebody shouts “go” or similar.
