To clear King IX IX difficulty as the King of Magic in 9 Kings, build the Keep early, place it safely in your backline behind durable stalling units, and funnel all resources into attack speed and spell scaling. This strategy converts the Keep into a hyper-scaling artillery battery whose high-frequency lightning strikes automatically target and eliminate enemy waves across the board before they can breach your territory.

Grid Setup and Defense Layers

Because the Keep targets enemies anywhere on the battlefield, it never needs to face frontline combat. Keep it safe in the backline or center grid behind sturdy blockers to prevent fast flankers and elite melee units from damaging it.

Grid LayerAssigned AssetsPrimary Tactical Function
Frontline PerimeterBarricades and durable defensive blockersAbsorbs initial rush charges and stalls elite melee units
Midline BufferCrowd-control anchors and utility supportsSlows advancing waves and bunches enemies together
Protected BacklineThe KeepFires continuous, uninterrupted lightning strikes across the board

Positioning stalling units directly in front of the Keep clusters incoming enemies together. As targets pack against your defensive line, consecutive lightning strikes hit the clumped groups in rapid succession, wiping out waves before they can break your barriers.

Deck Drafting and Pruning Priorities

King IX IX scales enemy health and numbers aggressively. Standard troop swarms suffer heavy attrition, making them costly gold sinks. Keeping your deck lean ensures you consistently draw Keep upgrades rather than diluting your card pool with redundant units.

  • Top Priority: Keep upgrade cards, attack speed boosts, and cast interval reductions that shorten the delay between lightning strikes.
  • Secondary Priority: Magic damage amplifiers and high-health stalling units that strengthen your frontline without requiring heavy gold investment.
  • Cards to Skip: Melee swarms, low-tier archers, and auxiliary damage towers that compete with the Keep for upgrade resources and deck space.

Prune or skip any card that does not stall enemy advances or accelerate the Keep's attack cycle.

Progression Sequence: Early Survival to Endgame

The Keep starts at a modest base attack speed, leaving your base vulnerable in the opening rounds if you neglect basic defenses. Manage your economy and build orders using the following progression:

  1. Deploy cheap frontline blockers: Use low-cost stalling units in the opening rounds to absorb early scouts and skirmishers without overspending gold.
  2. Erect the Keep: Build the Keep as soon as it appears in your drafts and position it directly behind your established blocker.
  3. Upgrade attack intervals immediately: Direct your early gold into the Keep's initial upgrade milestones to lower its strike interval to safe clearing speeds.
  4. Harden the frontline: Once lightning clearing stabilizes early waves, invest surplus gold into defensive reinforcements as wave densities increase.
  5. Maximize late-game attack speed: Push attack speed and spell scaling to their limits in the endgame. High-tier waves and bosses feature massive health pools; near-continuous lightning strikes are required to burn down bosses before elite enemies punch through your meat shields.
