Command An Army Evolution Guide — Every Line and What to Invest In

Command An Army has five main evolution lines, each three forms long, and every form is a straight upgrade of the one before. This is the progression system that matters most in the mid game: a committed line beats a lucky pull, because evolution rewards investment rather than summon luck. This guide lays out every line, which ones to prioritize, and how Ascension and Mastery stack on top.

What are the five evolution lines?

The spear line now has a third form. The Mongol update (early October 2026) added the Phalangite, a 4-star evolution of the Pikeman.

The same update gave the Mace an evolution, too. It used to be a standalone 3-star. Now it evolves into the Morningstar, a 4-star. We haven’t seen tested numbers for either new form yet.

The Crossbowman is still a standalone 3-star ranged unit with no evolution. Don’t pour line investment into it expecting a new form.

Which lines are worth investing in?

Ranked by what the tier lists and strategy guides actually reward:

1. Scout Rider → Cavalryman → Lancer (invest first). The payoff is the Lancer — a consensus top-tier unit, called the fastest in the game with the highest rush damage. Because it evolves from common pulls, this is the cheapest path to a top-tier unit in the game. If you are choosing one line to commit to, this is it.

2. Archer → Longbowman → Fire Archer (invest second). Ranged units decide fights in Command An Army, and the Fire Archer is the best 3-star ranged unit — creators describe the Crossbowman as its budget version, meaning the Fire Archer is the ceiling. Your backline is only as good as this line gets.

3. Shieldman → Sentinel → Imperial Wall (invest for defense). Defense objectives are won by shields, and this line is the accessible shield wall for players without a Spartan. Every stage earns its slot in a defending formation.

4. Spearman → Pikeman → Phalangite (invest one, always). Cheap and specialist: spears are the counter to cavalry, and the Lancer is the most popular rush unit in the game. One spear unit in your loadout is the difference between losing to every cavalry player and beating them.

5. Mercenary → Squire → Knight (invest if you like it). The balanced sword-and-shield line — solid, generalist, and the safest pick when you don’t know the matchup. It doesn’t headline any tier list, but it never embarrasses you either.

How do Ascension and Mastery stack on top?

Evolution is only one of three multipliers on a unit:

The combined effect is why creators repeat that a fully invested 2-star can beat a fresh 3-star: evolution is one axis, and Ascension plus Mastery can outweigh a single stage of it. The practical routine: pick your two or three lines, level and ascend everything you field, and let the summon pool fill in the rest.

How do stars and rarity fit in?

Units come from ⭐ to ⭐⭐⭐⭐⭐ rarity (the first 5-star, the Laestrygonian, arrived in the Mongol update), and higher stars are generally stronger — but the tier lists rank final forms, not pulls. A 1-star Archer is a long-term project, not a bad unit; the tier list tells you which projects are worth it.
