Knightica Gold and Unit Upgrade Guide for the Prologue

To survive the prologue stages in Knightica, spend your early gold to upgrade existing unit tiers before attempting to fill every open space on your grid. Board space represents spent resources, and deploying multiple weak level-one units leaves your army vulnerable to scaled enemy waves. Focusing on higher-tier units provides immediate boosts to health and damage output that keep your army financially sustainable.

Upgrading Unit Tiers vs. Filling Board Slots

Filling the combat grid with level-one troops quickly diminishes damage output relative to enemy health scaling. Unit tier upgrades increase core combat stats, giving individual characters the strength needed to hold defensive lines without cluttering the board.

When allocating upgrade currency across your current formation, focus on the specific threats present in active lanes:

Unit Role	Upgrade Priority	Practical Benefit
Front-Line Tank	High	Unlocks large survivability and health bonuses to anchor targeted lanes.
Ranged Damage	High	Boosts direct damage output to clear enemy waves before they break defenses.
Low-Synergy Unit	Low	Retain at base tier or sell when gold is needed for higher-priority units.

If a specific lane absorbs excessive damage during a wave, direct your tier upgrades to the units stationed in that lane instead of spreading gold evenly across all grid positions.

Managing Gold and Rerolls Between Waves

Transition windows between waves provide the opportunity to adjust your army composition and reinvest currency efficiently.

Audit your roster: Identify underperforming units or characters that no longer synergize with your main defensive line.
Sell surplus units: Sell dead-weight or low-tier units to reach the exact gold threshold required for a key unit tier upgrade.
Limit shop rerolls: Avoid spending gold on continuous store rerolls chasing ideal units. Work with available roster units to conserve funds for guaranteed upgrades.
Save a currency buffer: Maintain a small gold surplus after clearing waves easily. Storing unspent gold builds financial flexibility for incoming boss waves and late-prologue stat spikes.
