9 Kings: King of Progress Year 100 Defender Build Guide

To clear Year 100 in 9 Kings using the King of Progress, invest card drafts directly into uncapped Defenders to push their health pools into unreadable numbers, then attach Massacre so their eventual deaths trigger screen-clearing self-detonations.

The Core Engine: Uncapped Defender Health Scaling

Standard 9 Kings runs restrict individual unit tiers and level caps, forcing players to expand their rosters horizontally across limited board space. High-year enemy damage scaling quickly overwhelms standard capped frontlines, making wide, unspecialized boards ineffective for deep survival runs.

The King of Progress alters this progression curve by eliminating the level ceiling on Defender units. Instead of spreading resources across utility troops that succumb to late-game area-of-effect damage, focus draft choices vertically into your primary Defenders:

Vertical Investment: Funnel duplicate cards and level upgrades directly into core frontline Defenders rather than buying secondary support troops.
Unquantifiable Health Pools: Continuous leveling outpaces standard incoming burst damage. Eventually, Defender health values scale past legible numbers, creating a frontline that absorbs massive sustained punishment without crumbling.
Board Space Efficiency: Concentrating your survivability into hyper-leveled Defenders leaves your grid clear and minimizes economic waste.

Board Clear: Massacre Self-Detonations

An unkillable frontline alone cannot clear dense late-game enemy waves before timers lapse or enemies slip past. Attaching the Massacre trait turns the Defender's extreme durability into a high-yield offensive engine.

When a Defender equipped with Massacre finally succumbs to sustained focus fire, the unit detonates on death:

Cluster Enemies: Astronomical health pools draw incoming swarms and elite units into tight clusters around your frontline.
Trigger Detonation: When the Defender eventually falls, Massacre activates a massive corpse explosion across the packed cluster.
Wipe the Grid: The high-yield blast eliminates surrounding elite units and secondary swarms simultaneously.
Reset the Line: Surviving or newly deployed Defenders step into the cleared space to absorb the next push.

Progression Milestones to Year 100

Reaching Year 100 requires shifting focus from early economic survival to aggressive vertical level stacking and explosion damage.

Run Phase	Strategic Focus	Key Priority
Years 1–30	Board setup and initial defense	Draft baseline Defender cards and secure King of Progress leveling perks.
Years 31–70	Vertical level stacking	Pump all upgrades into Defender levels and equip Massacre for death explosions.
Years 71–100	Late-stage wave clearing	Push Defender health into unreadable tiers; rely on Massacre blasts to clear boss waves.

Prioritize Defender upgrades and Massacre above all ancillary options during mid-run drafts. By Year 70, standard unit trading becomes impossible against enemy scaling, leaving uncapped health and death explosions as your sole reliable clear mechanism.

Stopping Points Past Year 100

Runs do not force-end at Year 100. Mechanically, the King of Progress Defender build can continue indefinitely into Year 101 and beyond because uncapped health scaling and Massacre detonations remain functional against deeper waves.

However, deep runs encounter extreme visual red flashing and screen saturation caused by continuous damage numbers and constant multi-target explosions. This visual noise obscures unit placements, card drafting menus, and wave timers. Treating Year 100 as the natural victory milestone lets you fully prove the build's dominance before interface strain makes extended play impractical.
