Age of Origins C41 Officer Upgrade and Skill Guide

At City 41 (C41) in Age of Origins, focus your officer fragments on unlocking breakthrough star milestones for high-impact Warfare and Strategy officers rather than spreading resources across the entire roster. Your immediate priorities are Morgan for fleet size expansion and Tifa for overall damage output, backed by Zeus and Saki to ensure your frontline survives incoming attacks.

Officer Breakthrough Priorities at C41

Raw troop tier differences flatten in late-game engagements, making percentage-based breakthrough stats the primary differentiator in player-versus-player combat. Spreading purple and orange fragments across every officer slows progression; concentrate recruitment cards and fragments on your primary combat officers to reach five- and six-star breakthroughs.

Officer	Role	Core Breakthrough Benefit	C41 Priority
Morgan	Strategy	March capacity expansion and fleet defense	Highest
Tifa	Warfare	All-troop attack and high-tier damage scaling	Highest
Saki	Strategy	Fleet capacity growth and wounded ratio reduction	High
Zeus	Warfare	Frontline Melee HP and damage reduction	High
Alexandria	Warfare	Frontline durability and defensive reinforcement	High
Loreline	Logistics	Hospital capacity increase and healing cost reduction	Secondary

Strategy Officers: Maximizing March Capacity

Fleet capacity determines how much total offensive power and damage absorption you bring to an engagement.

Morgan: Advance Morgan first to maximize raw march size and rally limits. Larger fleets absorb area-of-effect damage from Titans and Warplanes more effectively.
Saki: Upgrade Saki directly after Morgan to compound fleet capacity bonuses and improve wounded conversion rates.

Warfare Officers: Frontline and Damage Milestones

A high attack stat is useless if your frontline collapses before backline units can deal damage.

Tifa: Scales overall fleet attack, making her the essential offensive anchor.
Zeus and Alexandria: Focus fragments here to increase Melee HP and defense. These defensive multipliers keep your frontline infantry and shredders alive against opposing strikes.

Skill Book Allocation and Optimization

At C41, officer skill slots must be reserved exclusively for combat-relevant multipliers. Break down common and uncommon skill books to craft skill experience and acquire higher-grade skill chests.

Recommended Skill Priorities

Melee HP and Melee Defense: Equip these onto your primary defensive officers. Frontline survivability protects your damage dealers from direct targeting.
Specialized Damage (LRA or MRA): Equip Long-Range Attack (LRA) or Mid-Range Attack (MRA) to match your city's focused troop type. Never split slots between Long-Range and Mid-Range skills on the same combat setup.
Fleet March Speed: Restrict march speed books to gathering or monster-hunting presets; do not take up combat slots with movement utility.

Skill Management

Even Distribution: Level up your equipped combat skills evenly across active officers to hit percentage leap thresholds efficiently, rather than dumping all skill experience into maxing a single slot.
Skill Resets: If you alter your city's troop composition (such as pivoting from Mid-Range to Long-Range), use skill reset items to recover 100% of your invested skill books for immediate reallocation.

Logistics Support for Sustained Battles

High-tier battles at C41 generate significant casualties. Neglecting Logistics officers leads to hospital overflow and permanent troop death during extended cross-server events.

Loreline and Jesse: Invest secondary fragments into Loreline and Jesse to raise hospital capacity and cut the resource costs of healing tier-11 and tier-12 units.
Resource Preservation: Lower healing costs reduce the strain on your food, oil, steel, and mineral reserves, allowing you to sustain consecutive rallies during events like the Void War and Capital Clashes.
