Cassius Infantry Garrison Guide in Doomsday: Odysseus Returns

To use Cassius effectively in Doomsday: Odysseus Returns, station him as your primary garrison commander to anchor base and alliance structure defenses against enemy rallies. His kit relies on absorbing incoming burst damage through an active shield while retaliating against multi-rally attackers with scaling counterattacks and defensive damage-reduction passives.

Skill Upgrade Progression

Prioritize Cassius's damage mitigation and active shield over raw offensive attributes. He requires focused investment in his defensive passives to withstand high-tier rally pressure from specialized offensive commanders.

Recommended Investment Stopping Points

1. Initial Milestone (5-1-1-1): Maximize his active skill first before unlocking secondary passives. The active shield provides the baseline survivability needed to prevent rapid garrison collapse.
2. Intermediate Milestone (5-5-1-1): Maximize his second skill to secure his core garrison damage reduction. Do not assign Cassius to defend high-stakes alliance buildings until he reaches this threshold.
3. Full Awakening: Maximize his remaining passives and awaken him. Awakening maintains his defensive stat floor and ensures damage mitigation remains functional even when garrison squad counts drop low.

Secondary Hero Pairings

Keep Cassius as the primary commander so his Garrison talent tree governs the defensive structure. Pair him with secondary heroes who provide sustained recovery, crowd control, or stat amplification.

• Adut (Best Sustain): Layers additional shielding and sustained healing over Cassius’s defensive barrier. This pairing offsets continuous chip damage, allowing Cassius to cycle his active shield safely through long sieges.
• Tom (Best Anti-Swarm): Provides crowd control and applies attack debuffs to surrounding enemy squads. Reducing enemy attack power directly amplifies the effectiveness of Cassius's flat damage-reduction passives.
• Liam (Accessible Counterattack): An accessible secondary option that boosts general infantry stats and counterattack output, increasing the damage dealt to rally leaders who remain locked in sustained combat.

Talent Tree Allocation

Allocate talent points exclusively into the Garrison and Infantry talent trees. Avoid spending points on March Speed or open-field mobility nodes, as they weaken structural defense thresholds.

1. Garrison Tree (Primary Focus): Path toward nodes that reduce incoming skill damage from rallies, expand garrison troop capacity, and provide flat defense bonuses while defending Shelters, watchtowers, and alliance structures.
2. Infantry Tree (Secondary Focus): Pick up nodes that increase infantry health, defense, and counterattack coefficients to maximize the squad's effective health pool.
3. Rage Generation: Secure all reachable rage-engine nodes across both trees to accelerate Cassius's shield refresh rate during sustained combat.

Tactical Weaknesses and Rally Countermeasures

While Cassius is an elite defensive anchor, specific attacking strategies bypass his strengths:

• Ranged Skill-Burst Rallies: Cassius relies on taking normal attacks to trigger his counterattack passives. Ranged commanders executing high-damage skill cycles outside direct contact reduce his retaliation value.
• Massive Swarm Pressure: Single and dual rallies feed his defensive engine, but unchecked swarm attacks can overwhelm garrison reinforcement capacity.
• Reinforcement Purity: Reinforce Cassius strictly with pure, high-tier infantry. Mixing troop types dilutes his infantry-specific defense talents and exposes the garrison to unfavorable combat matchups. Alliance members must monitor garrison health and cycle out wounded squads before defensive thresholds fail.
