To breach a fortress exceeding two billion power in Warhammer: Chaos & Conquest during Ulthuan campaigns, your alliance must coordinate specialized counter-rallies rather than attacking with uncoordinated solo hits or mixed compositions. Break through multi-layered defensive garrisons by scouting frontline unit types, optimizing your rally leader’s equipment, and landing chained rally waves seconds apart to overflow enemy hospital capacity.

1. Scout and Probe the Target's Defenses

Never start a full rally against a high-power fortress without verifying the defender's current setup. A two-billion power base typically holds tens of millions of troops across several tiers, often placing large numbers of low-tier units in front to absorb damage while backline Tier 4 and Tier 5 units deal heavy casualties.

Before setting a rally timer, execute the following reconnaissance steps:

  1. Send fast scouts or single-unit probe marches: Generate combat logs to verify whether the target is online, whether an active Peace Shield or anti-scout buff is present, and which unit category absorbs frontline damage.
  2. Inspect the defender's Champion equipment: Check whether the garrison Champion specializes in boosting specific unit stats, such as Infantry defense and health. Launching an assault without countering these stats will result in massive attacker casualties.
  3. Identify the primary garrison core: Determine whether the defense relies on Infantry walls, Cavalry stacks, or Monstrous units so the rally leader can select the proper counter-composition.

2. Optimize Rally Hosting and March Discipline

The rally host determines the march size and combat modifiers for the entire allied assault force. Always assign the alliance's strongest combat account to host the strike—specifically a player with high Fortress and Ritual upgrades, expansive Hall of the Chosen rally capacity, and high-tier Champion gear. Combat bonuses such as attack, armor piercing, and troop lethality provided by the host scale across all allied units inside the march.

All participating members must follow strict unit discipline:

  • Send only specified unit types: If the rally caller requests a Monstrous or Infantry march, send only that type. Off-type units do not benefit from the host's specialized gear and dilute damage output.
  • Prioritize high-tier troops: Fill slots with Tier 4 or Tier 5 units. Avoid sending low-tier filler that consumes valuable march space without providing sufficient combat stats.
  • Match march timers: Calculate march travel times in advance so the rally launches at full capacity without leaving open slots.

3. Chain Successive Waves to Overflow Hospitals

A multi-billion power target can absorb hundreds of thousands of casualties in a single battle because Healing Tents and Fortress hospitals immediately protect wounded units. A single isolated rally rarely zeros an active defender of this scale.

To inflict permanent losses:

  1. Coordinate multiple rally hosts: Organize two or more rally leaders to start timers against the target simultaneously.
  2. Synchronize arrival times: Time incoming rallies to land just seconds apart. Continuous impacts overwhelm the defender's hospital capacity. Once hospital beds fill, all subsequent defender casualties suffer permanent death rather than entering recovery.
  3. Intercept reinforcements: Successive impacts prevent the enemy alliance from safely sending reinforcements. Incoming support marches that arrive between tightly spaced hits often enter a burning fortress without proper defensive buffs, accelerating the defender's losses.

4. Secure Forward Positions and Manage Retreats

Operating aggressively in Ulthuan exposes forward bases to enemy counter-attacks while marches are away. To secure your alliance during the operation, enforce these safety precautions:

  • Maintain active Peace Shields: All alliance members who are not actively leading rallies or sending unlocked marches must keep Peace Shields active to prevent enemy counter-rallies.
  • Pre-plan fallback coordinates: Designate designated retreat coordinates before launching the initial assault.
  • Know when to cancel: If the defender activates high-tier combat buffs, receives massive elite reinforcements, or inflicts unfavorable casualty trades on initial waves, abort pending marches and teleport away immediately to preserve your warband.
