Black Obelisk

Black Obelisks are a Lash invention for generating energy. They are unique to Advance Wars: Dual Strike.

In-depth
Obelisks are completely impassable (even after destruction) and give no terrain stars. They cover nine squares, in a 3x3 square. They have one spot that can be attacked - the door at the front of the Obelisk. This weak point has similar defences to a Medium Tank. Black Hole units within two spaces of the Obelisk get 2HP restored, along with their fuel and ammo, for free. Along with the Black Crystals, they are the only way to repair an Oozium.

They act as the main source of Black Hole's power in Dual Strike and were invented by Lash for the Bolt Guard's campaign in Omega Land. They produced massive amounts of energy and materials, but turned the surrounding area into desert and wasteland. They appear twice in the Campaign mode, and are the main objective in both maps they appear on.

First, one appears in Crystal Calamity. This Obelisk is protected by a barrier generated by the Black Onyx, as well as a Black Cannon and an army commanded by Kindle and Koal. To destroy it, the Allied Nations have to use some specially adapted anti-sattelite missile silos to destroy the Onyx, then attack the Obelisk.

The second and final Obelisk is found in the mission For the Future!. Von Bolt himself commands an army to guard the Obelisk, including four Minicannons and three Black Crystals.
