Warhammer: Chaos & Conquest: Altdorf Warband Siege Guide

To capture the imperial capital of Altdorf in Warhammer: Chaos & Conquest, your alliance must organize high-capacity warbands under an optimized rally leader, teleport an allied hive directly next to the capital, and commit elite high-tier units while rotating continuous strikes. Capital sieges demand collective power scaling into hundreds of millions to break fortified garrisons and absorb defensive retaliation.

Designating and Equipping the Warband Lead

Solo marches cannot break an entrenched capital garrison. In large-scale conflicts, such as the Ludwig 4 server siege where alliance KalipoDeLomo [KDL] launched a 650-million-power assault against The Mandalorians [MAND], assault success depends on concentrating allied power into a single optimized march.

Because all contributing players inherit the rally leader’s offensive stats and siege multipliers, the designated lead must have:

• Maxed Warband capacity rituals to maximize the total number of allied troops in the march.
• High-tier Warband Hall upgrades to expand reinforcement limits.
• Combat gear, warlord choices, and champion builds fully focused on army assault stats and siege bonuses rather than utility or resource gathering.

Any statistical weakness in the lead's setup dilutes the combat effectiveness of every contributed unit.

Clustering Alliance Hives Adjacent to Altdorf

Positioning is a primary tactical variable during capital sieges. Before launching an assault, allied keeps must teleport into a dense hive cluster directly adjacent to Altdorf.

This positioning provides three vital advantages:

• Compressed March Times: Staging from the edge of the capital reduces march transit to minutes. Defending alliances have minimal warning to scout incoming forces, cycle garrison units, or adjust defensive counters.
• Mutual Reinforcement: Contributing troops to an offensive warband temporarily depletes a keep's home defense. Clustered keeps provide overlapping defensive coverage, allowing alliance members to reinforce vulnerable keeps quickly if defenders attempt counter-attacks.
• Denial of Teleport Space: Dense packing prevents enemy keeps from jumping into optimal flanking positions or sending disruptive blocking marches across your rally path.

Rally Composition and Unit Filtering

Frontline collapse is the fastest way to fail an Altdorf siege. Defending garrisons deal substantial opening burst damage, requiring durable frontlines to protect specialized damage dealers.

Alliance leadership must filter rally contributions strictly. Avoid low-tier filler units entirely. Low-tier troops fall rapidly in combat calculations, inflicting early morale penalties on the warband and granting favorable trade efficiency to defenders.

Staggering Follow-Up Waves to Outlast Reinforcements

A single assault rarely clears a fully fortified imperial capital. Defending alliances constantly route fresh reinforcements into Altdorf from surrounding keeps to replace fallen frontlines.

To break this cycle, the attacking alliance must prepare follow-up warbands before the initial hit lands:

1. Launch secondary rallies timed to hit moments after the initial battle resolves.
2. Hit the garrison before the defending alliance can reorganize reinforcements or treat wounded units.
3. Review scout and combat reports immediately after each impact to detect shifts in the defender’s troop types, altering subsequent rally compositions to maintain combat advantages.

Managing Medical Capacity and Resource Burn

Committing hundreds of millions in power exposes attacking players to severe hospital overflow. Any casualties that exceed your hospital capacity become permanent troop losses, creating lasting power deficits for the alliance.

Before committing forces to an Altdorf assault:

• Expand hospital capacity by upgrading healing wards and completing medical rituals.
• Stockpile substantial reserves of Iron, Food, Stone, and Warpstone speedups to instantly heal wounded troops between combat waves.
• Establish a strict loss ceiling before launching. If casualty exchange rates become heavily unfavorable, alliance leadership must halt the assault to prevent unsustainable troop attrition across the alliance.
