Why is the shield line good for beginners?
The line
| Stage | Star | Role |
|---|---|---|
| Shieldman | 1★ | The starter frontline. Slow, tanky, no damage. |
| Sentinel | 2★ | Tanky 2-star with stats close to Spear Militia. |
| Imperial Wall | 3★ | The final form. Creators describe the frontline as “unstoppable” with it. |
This is the only shield line that starts at 1 star, which makes it the cheapest way to put a wall in front of your army. That price is the point — see why star cost matters.
What the line actually does
Shields do not kill things. They occupy space and absorb fire so that the units which do kill things — Flame Archers, Berserkers, Samurai — survive long enough to work.
Creators are split on how to rank that. One rates Shieldman C tier on the grounds that it has no offensive capability. Another rates it B tier and pushes back on exactly that logic: “you don’t really need offensive capabilities if you’re a tank — you might as well use this to hold points.” Both descriptions are accurate; they disagree about whether holding points is valuable enough.
In practice the answer depends on your lineup. If your damage units are unprotected, a shield is worth more than another damage unit. If you already have a Spartan anchoring the line, a second shield adds less.
The beginner case
The strongest argument for this line is not the unit — it is the cost curve.
Shieldman, Sentinel and Imperial Wall cost 1, 2 and 3 stars. A Spartan costs 4. On a 13-star budget, an Imperial Wall plus a Samurai leaves you four stars for the rest of the lineup; a Spartan plus a Samurai leaves you five but no frontline under the Spartan.
That makes the shield line the standard recommendation for a new account: it is the cheapest way to field a real frontline, and it scales all the way to 3 stars without ever becoming unaffordable.
What counters shields
Hammers. The Mace is the game’s only hammer unit, and it is the designed counter to shields — creators describe it as walking through a shield line and crushing it.
The wider rule is block damage. Any unit with block damage in its stat panel counters shields, which includes the Halberdier and the Javeliner. Since Command An Army never shows a counter chart, hovering over a unit to check for block damage is the only reliable test — the unit counters guide covers the full method.
Shields also have a soft counter: they are slow, so a fast composition can simply avoid them and hit the units behind. A shield wall that nobody attacks is doing nothing.
How to use the line
Put them in front, not around. Shields exist to eat the first volley and the first charge. Placing them anywhere else wastes the unit.
Pair with ranged, not with melee. The classic beginner composition is shields in front and archers behind — the shield absorbs the approach, the archer does the damage. Creators describe this pairing as the way to make Shieldman “really fine against hammers,” since the hammer has to reach the shield while being shot.
Do not expect them to win alone. A shield line with no damage behind it loses slowly instead of quickly. That is still a loss.
Consider them a budget answer to Spartans. If you cannot field a 4-star Spartan, the Imperial Wall holds a line at 3 stars and leaves budget for a damage carry. The tier list ranks Spartan higher; the star limit is why you might still pick the Wall.
Where it sits
The shield line is B tier on the best units tier list — good, not glamorous, and cheap enough to be in almost every beginner lineup. For the units that should stand behind it, see the Archer line and the Halberdier line, or start from the beginner guide if you have not picked a lineup yet.
