How to Get Gems: Expedition is a large one-off gem source.

Quick Answer

Expedition is a permanent single-player campaign against preset enemy marches. Troops used are simulated — nothing dies, nothing goes to hospital, so you can retry a stage as many times as you like. Each stage awards up to three stars, and your star rating sets your recurring daily chest. Clearing stages earns Medals of the Conqueror for the Expedition store, which sells commander sculptures. For a newer account it is the largest pile of free rewards sitting untouched in the game.

Overview

Expedition is buried in the menus, it does not chase you with notifications, and it is worth a genuinely large amount to any account that has not pushed it. The two reasons to care:

Free rewards at scale — gems, sculptures and a daily chest that improves permanently as you clear stages.
Zero-risk experimentation — the only place you can test a commander pairing against a real fight without paying for it in dead troops.

The Rules That Make It Free

Expedition troops are simulated. Units defeated during a stage do not permanently die and do not enter your hospital. You can retry a hard stage endlessly, changing pairings, formations, targeting order and buffs between attempts, and it costs you nothing but time.

This is the opposite of every other combat mode in the game, and it is why Expedition is the correct place to learn how troop counters and skill timing actually behave.

How Stages Scale

Two things ramp as you progress, and knowing the breakpoints stops you from getting stuck:

Your marches — you get more of them as you advance:

From stage	Marches
Start	1
6	2
16	3
26	4
41	5

Enemy commanders — they get more skills as their star level rises:

From stage	Enemy stars
Start	1★
11	2★
21	3★
31	4★
41	5★
51	6★

The number of skills an enemy commander has unlocked tracks its star level, so the difficulty steps are sharp at stages 11, 21, 31, 41 and 51 rather than gradual. If you suddenly hit a wall, check whether you just crossed one of those.

Stars and the Daily Chest

Each stage awards up to three stars based on how cleanly you clear it. This is the part people miss: your best star rating on a stage feeds a recurring daily chest, which you can collect by replaying completed stages.

That makes three-starring old stages worth going back for. It is not a vanity metric — it is a permanent increase to your daily income.

Medals of the Conqueror and the Store

Clearing stages earns Medals of the Conqueror, spent in the Expedition store. What is worth buying:

The featured epic commander sculpture, which rotates weekly. This is the main draw — a steady free sculpture stream for whichever epic is up.
Constance sculptures — a cheap gathering specialist worth having; see best gathering commanders.
Aethelflaed sculptures, capped at a small number per day, which is why consistent visits beat occasional ones.

The daily cap on some items is the key detail: the store rewards checking in regularly rather than saving up and spending everything at once.

How to Push Expedition

Bring your best-built pair, not your highest-power one. Skill levels carry the fights here.
Retry freely. There is no cost. If a stage beats you, change the pairing rather than levelling up and coming back.
Mind the star breakpoints. Stages 11, 21, 31, 41 and 51 are where enemies gain skills.
Go back and three-star old stages once your commanders improve. That raises your daily chest permanently.
Collect the daily chest. Every day. It is free and it takes one tap.

FAQ

Do you lose troops in Expedition?

No. Expedition troops are simulated — losses do not persist and nothing enters your hospital. Retry as often as you like.

How many marches do you get in Expedition?

One to start, two from stage 6, three from stage 16, four from stage 26 and five from stage 41.

What are Medals of the Conqueror used for?

The Expedition store, which sells commander sculptures — a rotating featured epic, plus Constance and Aethelflaed with daily limits.

Is it worth replaying Expedition stages?

Yes. Your star rating sets a recurring daily chest, so three-starring earlier stages permanently improves your daily income.

Why did Expedition suddenly get harder?

You probably crossed a star breakpoint — enemy commanders gain skills at stages 11, 21, 31, 41 and 51.

Is Expedition worth it for free players?

It is one of the biggest untapped reward piles for any account that has not pushed it, and it costs no resources at all.
