Core Rules & Gameplay
Legions Imperialis’ core rules, detailed within the Liber Strategia, cover movement, range, line of sight, terrain interaction, the combat phase, and morale/leadership mechanics.
Movement and Range
Legions Imperialis utilizes a unique movement and range system designed for epic-scale battles. Units aren’t moved individually, but rather as formations, representing vast armies maneuvering across the battlefield. The Liber Strategia details how these formations move, factoring in terrain and unit type. Range is similarly abstracted, with weapons having different ranges measured in inches, impacting engagement distances.
Movement is typically measured in distances appropriate for the scale, and different unit types – infantry, vehicles, titans – possess varying movement characteristics. Terrain significantly impacts movement; difficult terrain slows formations, while impassable terrain blocks movement entirely. Understanding these rules is crucial for positioning your forces effectively. Range dictates how far a unit can engage the enemy, influencing tactical decisions about deployment and advance. Mastering these core mechanics is fundamental to success in Legions Imperialis.
Line of Sight and Terrain
Legions Imperialis features a streamlined line of sight (LOS) system, crucial for determining which units can target each other across the expansive battlefields. The Liber Strategia clarifies how LOS is determined, accounting for the scale of the game and the presence of terrain. Unlike some wargames, complete obstruction isn’t always necessary to break LOS; partial cover can impose penalties.
Terrain plays a vital role, offering cover and disrupting lines of sight. A variety of rules within the Terrain section (page 66 of the Liber Strategia) allow players to utilize diverse terrain pieces. Forests, ruins, and hills all affect LOS differently, providing tactical advantages or disadvantages. Determining whether a unit has a clear line of sight to its target is a fundamental step in the shooting phase, influencing both accuracy and effectiveness. Careful terrain placement is key to defensive strategies.
The Combat Phase: Attacks and Saves
The Legions Imperialis combat phase resolves attacks and saves, determining the damage inflicted upon enemy units. This phase, detailed within the core rules of the Liber Strategia, utilizes a dice-based system, modified by unit characteristics and tactical considerations. Attacks are generated based on a unit’s weaponry and firing capabilities, while saves represent the target’s ability to withstand incoming fire.
The rules outline how to calculate hits, applying modifiers for range, cover, and special abilities. Successful hits then require the defending unit to make a save, using its armor value or other defensive statistics. Damage is applied after successful saves are failed, reducing a unit’s strength or potentially destroying it. Understanding the interplay between attack values, save values, and modifiers is crucial for maximizing combat effectiveness in this epic-scale wargame.
Morale and Leadership
Legions Imperialis incorporates robust morale and leadership rules, reflecting the psychological impact of battle on massive formations. The Liber Strategia details how units react to casualties and adverse events, potentially becoming shaken or even routing from the battlefield. Leadership plays a vital role in maintaining unit cohesion, with commanders and heroic characters able to rally troops and prevent demoralization.
These rules aren’t simply about removing units; they represent the cascading effects of fear and loss of control within a large army. Factors like heavy casualties, enemy flanking maneuvers, and the death of key leaders can all trigger morale checks. Successful checks maintain unit effectiveness, while failures can lead to reduced combat performance or complete collapse. Mastering these rules is essential for simulating the brutal realities of warfare on an epic scale.
Army Composition & Units
Legions Imperialis allows diverse army construction, featuring Legiones Astartes, Solar Auxilia, Knights, and Titans. The Liber Strategia provides detailed unit profiles and formation options for strategic depth.
Legiones Astartes: A Focus
The Liber Strategia dedicates significant attention to the Legiones Astartes, providing comprehensive rules for all eighteen Legions within Legions Imperialis. Each Legion benefits from unique characteristics and tactical doctrines, influencing army composition and battlefield strategies. Players can meticulously construct forces reflecting the specific strengths and weaknesses of their chosen Legion, from the relentless aggression of the World Eaters to the calculated precision of the Iron Warriors.
Detailed unit profiles outline the capabilities of each Astartes unit, including infantry squads, dreadnoughts, and powerful characters. The rulebook delves into formation options, allowing players to create cohesive and effective battle groups. Furthermore, the Legiones Astartes section explores Legion-specific wargear and enhancements, adding another layer of customization and tactical flexibility. Mastering the nuances of each Legion is crucial for achieving victory in the epic conflicts of the Horus Heresy, as presented within the Legions Imperialis system.
Solar Auxilia: Supporting Forces
The Solar Auxilia represent the backbone of the Imperial war machine in Legions Imperialis, offering crucial support to the elite Legiones Astartes. The Liber Strategia provides extensive rules for fielding diverse Auxilia formations, encompassing infantry cohorts, armored vehicles, and artillery batteries. These forces excel at providing firepower, screening elements, and objective control, complementing the Astartes’ aggressive assault capabilities.
Players can construct Auxilia armies tailored to specific battlefield roles, utilizing a wide array of unit types. From the stalwart infantry of the Krieg to the heavily armored tanks of the Fellian-pattern, the Solar Auxilia offer tactical versatility. The rulebook details formation guidelines, wargear options, and special rules unique to various Auxilia regiments. Effectively integrating the Solar Auxilia into your army is paramount for achieving battlefield dominance within the grand scale of Legions Imperialis warfare, providing essential resilience and sustained firepower.
Knights and Titans: Heavy Support
Knights and Titans represent the ultimate in Imperial firepower within Legions Imperialis, serving as devastating heavy support elements capable of shattering enemy formations. The Liber Strategia dedicates significant rules coverage to these colossal war machines, detailing their construction, weaponry, and battlefield roles. Players can field a variety of Knight patterns, from the nimble Cerastus to the imposing Kastelan, each possessing unique strengths and weaknesses.
Even more formidable are the Titans, towering engines of war that dominate the battlefield. The rulebook provides comprehensive guidelines for assembling and deploying Titan Legions, including rules for command hierarchies and linked firepower. Mastering the deployment and coordination of Knights and Titans is crucial for exploiting their immense destructive potential. These units are not merely brute force; tactical positioning and synergistic integration with other forces are key to maximizing their impact in the epic conflicts of Legions Imperialis.

Strategic Considerations for Epic Scale Warfare
Legions Imperialis demands a shift in strategic thinking compared to standard-scale wargames. The sheer size of battles necessitates a broader perspective, focusing on manipulating entire formations rather than individual units. Effective deployment and coordinated maneuvers are paramount to success. Consider terrain’s impact – utilizing cover and chokepoints to funnel enemy advances is crucial.
Force composition is also key. Balancing firepower, mobility, and resilience is essential. Heavy support elements like Knights and Titans can dominate the battlefield, but require careful protection. Understanding unit roles and synergies within your army is vital for maximizing effectiveness.
Anticipating your opponent’s strategies and adapting your plans accordingly is critical. Epic-scale warfare rewards players who can think several turns ahead and exploit weaknesses in their enemy’s formation. Mastering these strategic elements will elevate your gameplay in Legions Imperialis.
