How to Get Knight in Command An Army: Evolution, Not Summons

The Short Answer: Evolve a Mercenary

Knight is not a banner pull. It is the endpoint of the Mercenary evolution chain — the longest of the five documented paths in the game:

Two station visits and two level-20 thresholds stand between the weakest base unit in the roster and a clean line-breaker. The evolution guide documents all five paths; this page is the Knight branch.

The Chain, Step by Step

1. Hold a Mercenary (1★). It is the lowest-performing combat unit in base form — its only reason to exist is this chain.
2. Level it to 20 (the evolve threshold per player reports) and evolve at an evolve station → Squire (2★). Squire is acceptable at both offense and defense, but its real value is still the path.
3. Level Squire to 20 and evolve again → Knight (3★, B tier).
4. Ascend in parallel. Duplicates of any unit in the chain feed ascension — two copies per level up to Ascension 3 — which permanently strengthens the copy you already keep while you grind the evolutions.

The beginner guide covers the leveling loop that feeds step 2, and the unit tier list ranks the endpoint against everything else you could field at 3 stars.

What Knight Is Worth at the End

Knight is the dedicated line-breaker of the roster: it breaks entrenched formations cleanly and does that one job better than anything near its cost. The problem is timing. The chain is the longest in the game, and by the time a fully levelled Knight arrives, S and A tier units start outpacing it in late-game scenarios.

That makes Knight a hold-first, not a goal-first path: run it if you already hold a Mercenary and spare Mastery time, not as a planned project the way you would run the Scout Rider chain toward Lancer. If you want an evolution endpoint that stays S-tier relevant, the Flame Archer chain finishes a full tier higher at the same star cost.

Knight vs Rapier Knight: Not the Same Unit

Update 2 added Rapier Knight, and the name overlap causes real confusion. They are different units:

Rapier Knight comes from the banner, carries the Parry trait, and has no published star rating or confirmed evolution requirement. This page’s chain has nothing to do with it. The Update 2 overview covers the Rapier line in full.
