War and Order: Should You Upgrade Castle or High Technology?

Upon reaching Castle Level 31 in War and Order, your priority should be unlocking your next troop tier through Castle and building upgrades before heavily investing in the High Technology tree. While High Technology grants permanent percentage-based combat statistics, higher-tier soldiers provide superior base attributes and combat performance that raw research percentages on lower-tier units cannot match.

The most effective progression model is a staggered milestone approach: claim the initial, low-cost High Tech nodes immediately, resume pushing your Castle until your next tier of military recruitment is secured, and then shift resource reserves into deeper High Tech research.

Castle Upgrades vs. High Technology

At Castle Level 31, progression branches between vertical infrastructure growth and deep research. Both paths demand substantial quantities of wood, food, stone, iron, and speedups.

Castle Upgrades: Pushing your Castle beyond Level 31 unlocks higher-tier recruitment buildings, increases base march capacities, and raises Hall of War rally limits. Higher-tier units fundamentally outperform lower tiers due to innate survivability and higher base damage.
High Technology: Unlocked at Castle 31, this research tree provides percentage bonuses to troop attack, defense, health, damage mitigation, and march size. These bonuses act as multipliers on your existing units' base statistics.

Because High Tech buffs scale from base unit attributes, applying percentage bonuses to lower-tier troops yields lower absolute combat gains than upgrading to the next unit tier.

Progression Focus	Primary Benefit	When to Prioritize
Castle Push	Higher troop tiers, larger base march and rally size	Approaching key troop unlock thresholds
High Technology	Permanent combat stat multipliers and damage mitigation	Sitting at a completed troop tier while gathering resources
Hybrid Stagger	Quick early stat gains followed by structural progression	Freshly reaching Castle Level 31

When to Shift Focus to High Technology

Once you secure your immediate troop tier target or hit a severe resource bottleneck on Castle prerequisites, redirect your focus to High Technology.

High Technology decides battles between opponents fielding the same unit tiers. In mirror matchups, players with higher damage reduction and health nodes suffer fewer hospital casualties and win trades during territory battles, Crown Wars, and defensive stands. Prioritize early nodes that boost march size and survivability to maximize immediate combat value.

Resource and Speedup Strategy

To prevent progression stalls, coordinate your expenditures with kingdom calendar cycles:

Align with Server Events: Save major Castle upgrades and deep High Tech research projects for events such as King of the World or development stages that award milestone points for building power and research power.
Separate Speedup Types: Allocate general speedups to long building timers during construction-focused event phases. Reserve research-specific speedups exclusively for High Technology milestones.
Grab Low-Hanging Research First: Research the entry-level High Tech nodes right after reaching Castle 31, as they require minimal materials and provide quick stat increases without draining the reserves needed for future building requirements.
