To scale army power rapidly in 9 Kings, pair Monarch passive abilities with units that possess death triggers, then place those expendable units on your front line. When front-line units fall in battle, their death triggers pass permanent stats, board-wide buffs, or extra unit spawns directly to your protected back-line damage carries before the engagement ends.

Aligning Unit Recruitment With Monarch Traits

Your Monarch's passive ability determines which unit synergies will effectively scale your damage output. Examine your Monarch's trait text early in a run to focus your recruitment strategy:

  • Sacrifice and Death-Bonus Monarchs: Prioritize units that leave behind permanent stat boosts, board-wide buffs, or damage effects upon leaving the field.
  • Swarm and Token Monarchs: Target low-cost units or cards that spawn extra unit copies on death to maintain constant board presence and capitalize on death-count passives.
  • Synergy Over Raw Rarity: Select lower-rarity units that directly activate your Monarch’s passive mechanics rather than high-rarity units that lack trait synergy.

Board Positioning and Unit Roles

Proper placement forces sacrificial units to die early in combat, transferring their buffs to main damage dealers before your back line takes damage.

Back LinePrimary Damage CarriesStay protected behind sacrificial units while gaining incoming stats and board buffs.

Mid-Game Transitions and Pivot Rules

Enemy scaling ramps up during mid-game waves. If your board setup is not producing sufficient damage multipliers, adjust your strategy using these steps:

  1. Sell Unsynergized Units: Sell off high-stat units that lack death triggers or trait synergy to free up board space and refund currency for rerolls.
  2. Search for Recursive Mechanics: Look for relics or cards that create recursive loops, such as units that spawn copies of themselves paired with Monarchs that scale on total unit casualties.
  3. Pivot Away From Failed Loops: If key loop components fail to appear, switch to standard board-control units rather than spending currency to force an incomplete build.
