9 Kings: King IX IX Soldier Swarm Strategy Guide

To beat King IX IX in 9 Kings with a soldier strategy, flood the board with disposable infantry spawners rather than investing in solitary high-cost carries. King IX IX imposes massive enemy stat scaling and rapid wave tempo that easily overwhelm single-target tanks. Counter this incoming burst by creating a continuous frontline meat grinder where flat stat buffs multiply across dozens of basic Soldiers simultaneously.

Early-Game Drafting Priorities

Your opening priority is securing consistent, low-cost Soldier generation cards to prevent early lane breaches. Failing to establish early body volume leaves your castle open to fast leaks during initial campaign years. Commit early gold strictly to recruitment camps and barracks, passing on expensive high-rarity utility cards until your production line is stable.

Stat Buff Order: Survivability Before Attack

Unbuffed Soldiers cannot survive King IX IX cleave attacks and ranged volleys. If basic units die to incidental area-of-effect damage before swinging, your swarm collapses.

1. Secure flat health first: Invest in baseline durability bonuses so Soldiers survive at least one or two standard hits from incoming enemy units.
2. Layer flat attack power: Once troops survive stray hits, stack flat attack modifiers across your board. Because basic Soldiers strike in dense clusters, minor flat attack increases yield massive collective damage per second.
3. Avoid one-sided scaling: Over-investing in pure attack leaves spawn points vulnerable to wipeouts, while stacking only defense creates stalled lanes that fail against wave timers.

Grid Positioning and Movement Lanes

Grid placement determines whether Soldiers march into combat smoothly or bottleneck behind friendly infrastructure. Arrange your kingdom grid in three clear operational layers:

• Protected Rear Generators: Place barracks and recruitment camps along the back boundary of your grid to shield them from incoming siege fire and direct attacks.
• Central Buff Belts: Position stat-boosting monuments and aura-granting totems along the central corridors directly adjacent to marching lanes so every passing Soldier gains active bonuses.
• Forward Staging Lanes: Keep the frontline grid clear of obstructive buildings so freshly produced units march directly toward incoming enemy corridors without pathing delays.

Late-Game Deck Pruning and Boss Encounters

Late-game King IX IX bosses feature massive health pools that resist burst damage. Defeat them by maintaining continuous unit flow to surround and body-block the boss, locking enemy movement while dense rings of infantry whittle down the boss's health bar.

To keep this loop running in later years, protect your draw consistency:

• Skip situational utility cards: High-cost spells and niche cards dilute your draw pool when you need constant stat multipliers and production reinforcements.
• Preserve gold for shop rerolls: Maintain a reserve to dig specifically for infantry upgrades and spawn capacity rather than settling for off-synergy picks.
• Commit every board tile to the swarm: Dedicate all remaining spatial capacity to reinforcing frontline volume, ensuring dead Soldiers are instantly replaced.
