Traits and the skill tree in Command An Army

From traits to a skill tree

Before Update 3, the game used a trait system: a set of different abilities that could be unlocked and that were meant to balance the game between players. The Update 3 leaks describe a rework where traits are replaced by a trait system built on a skill tree. One creator summarized it as traits being scrapped in favor of skill trees, while another described the skill tree as the new home for unit traits rather than a separate system. Either way, the throughline is a tree you progress along instead of a flat list of toggles.

The skill tree logic shown in the leaks is simple to describe: you unlock the first trait, then move along that branch to unlock the next one. Creators point to examples such as a giant skill tree that branches into four, and a lancer skill tree update, which suggests each unit family gets its own branch rather than one shared tree.

What traits do

A trait, in the system the leaks describe, is a set of different abilities that can be unlocked, and the stated goal is to balance between players rather than to hand one side a permanent edge. The post-launch breakdown videos frame traits as unit features you gain, and they sort units into roles and archetypes so you can see which troop fits which job.

Archetypes after the new units

One post-launch creator published an archetype master sheet that sorts units into roles after the new units landed. It explains trait values and walks through individual traits such as Sweep, a fourth trait, and raw fighting ability, and it claims eight different archetypes were built around the three new units, with more possible as the roster settles. The takeaway for you is that the new traits change which units fill which role, so a unit that was mid-tier before Update 3 may move up or down once the tree is fully mapped.

What is live now, and where to read it

Everything above this paragraph is dated between 2026-09-28 and the Update 3 launch, so it describes the run-up rather than the shipped system. Once the update went live the skill tree stopped being a leak and became a mechanic with rules you can read off your own screen, and those rules are written up separately on the skill tree page. The distinction matters: a leak tells you a system exists, while the post-launch recordings tell you how to spend on it, and the two answers can differ on details.

Where the trait system fits

The trait and skill-tree system ships alongside the Mongol faction rather than replacing it. The two are covered together on the Mongol units page, the seasonal track that funds it is on the battle pass page, and the full update timeline lives on the updates page. If you want the unit roster itself, the unit database carries every named troop we can trace to a source.
