Notes
  • The boss always starts with Activate Arcanotron (Heroic). Although not stated on their tooltips, each Hero Power when used will replace itself with the next on the list, until Activate! (Heroic) is reached.
  • All of the above Hero Powers except Activate! are auto-cast, and will be used at the beginning of each turn if possible. However, the varying mana cost means this will not always be possible, in which case the Hero Power will not be used (and thus will not be replaced), and the mana may be spent otherwise.

Strategy[]

The central mechanic for the Omnotron Defense System encounter is the boss' shifting hero powers, and the various Trons that are generated by them. The boss starts with Activate Arcanotron (Heroic), but once this is used it will be replaced by Activate Toxitron (Heroic), followed by Activate Electron (Heroic) and Activate Magmatron (Heroic), with the switching presumed to end with Activate! (Heroic). All hero powers except Activate! are auto-cast, but due to their mana cost may not be usable during earlier turns. Until Activate! is acquired, the boss will use their current hero power at the very start of the turn, whenever possible.

Lore[]

Blackrock Mountain[]

The Omnotron Defense System was once a plaything of the Dark Iron dwarves left forgotten in Blackrock’s depths. Nefarian has taken to tinkering with them, and he’s adjusted his pet project’s “Murder” setting to 11.[1]

World of Warcraft[]

"Hmm... the Omnotron Defense System. Centuries ago these constructs were considered the Dwarves' greatest tactical achievements. With so many counters to each construct's attacks, I'll have to rectify these designs for them to provide me any entertainment." - Nefarian

The Omnotron Defense System, also known as Tron Council and the Omnotron Council is a council-type boss encounter in Blackwing Descent.

The bosses' starting positions are (from left to right if you are facing them from the entrance of the room) Magmatron, Arcanotron, Toxitron, and Electron.

Dungeon Journal

The Omnotron Defense System was once touted as the Dark Iron dwarves' greatest technological marvel. When Nefarian arrived in Blackwing Descent, he repurposed the run-down system to annihilate anyone intruding on his laboratories.

Trivia[]

  • The boss' emote response dialogue echoes Annoy-o-Tron's summoning quote Hello! Hello! Hello!, with the response apparently downloaded by the Omonotron Defense System as part of an OS update.
