Command An Army Gems — How to Earn, Spend & the Pity System
How to earn gems fast in Command An Army: codes, wins, quests, selling duplicates — and how to spend them on summons, evolution and luck potions without wasting your pity counter.
Gems are the entire Command An Army economy — they pay for summons, evolution, luck potions and nothing else. Every unit you field, every evolution step and every banner pull runs through gems, which is why knowing how to earn and spend them separates accounts that grow from accounts that stall.

How to Earn Gems
| Method | Gems | Notes | |
|---|---|---|---|
| Win a match | ~75 | Active | Losses pay almost nothing (~10) — finishing matches matters more than starting five |
| SORRY code | 1,000 | Working | The biggest single code reward on camera |
| OPTIMIZE code | 700 | Working | On camera — Sept 18 footage |
| SHIELDBREAKER code | 700 | Working | On camera — Sept 18 footage |
| Sell a 3★ duplicate | ~500 | Active | Your gacha trash is currency — 500 for some 3★s |
| RELEASE / WAR / COMMANDER / CONQUER / CONQUEROR code | 500 each | Working | Five codes × 500 gems each |
| Quests | Varies | Active | E.g. hit 500 enemies with mounted rush attacks — steady trickle |
| Capture points + kills | Varies | Active | Feeds the score that converts to gems at round end; player kills worth the most |
| RANKED code | 300 | Working | Media-reported — matches the new ranked mode |
| GUILD code | 300 | Working | Media-reported — matches the new guilds mode |
| PARRY code | 300 | Media-reported | New Update 2 code — amount not shown on camera |
| RAPIER code | 300 | Media-reported | New Update 2 code |
Five of these methods are passive or one-time (codes, quests, selling) — the other three are the active loop you repeat every session: win matches, capture points, get kills.
How to Spend Gems Without Wasting Them
The summon screen is a rotating gacha with five rules that determine whether your gems build an army or evaporate: Seen in footage · 2026-09-22
- Banners rotate and feature specific units. The odds shown on screen differ between banners — the same unit has been seen at 0.15% and 0.19% on different banners. Check the odds before spending.
- The pity counter is real. A guaranteed 4★ arrives at 400 summons on a banner, and the counter persists across sessions. Long-term players should track it instead of chasing single pulls.
- Duplicates are not trash. Two copies of the same unit combine into an Ascension (capped at 3); anything past that sells for gems.
- Luck potions boost a summon session — save them for a banner you actually want.
- Chase evolutions, not just rarity. A 1★ Archer grows into the best ranged unit in the game; a 4★ Spartan never evolves but is already S tier.
What Not to Spend Gems On
- Do not buy gems with Robux until you have exhausted the free economy. The Exclusive Pack (1,000 Robux) exists, but the free gem flow from codes and wins is substantial enough for most accounts.
- Do not chase a single 4★ at the expense of evolution currency. Evolution also costs gems on top of the level-20 grind — a balanced account needs both.
- Do not ignore the pity counter. If you are at 350/400 summons on a banner you like, spending elsewhere resets the progress toward your guaranteed 4★. Seen in footage · 2026-09-22
The Gem Economy Loop
The fastest-growing accounts treat gems as a cycle, not a straight line: Community report · 2026-09-22
Codes → gems → summons → duplicates → ascend the useful ones → sell the rest → gems → more summons.
Every stage feeds the next. The players who stall are the ones who summon once, get a dupe, and stop — instead of chaining the loop through codes, wins and sells.
Skill Crystals — the Second Currency
The Skill Tree runs on skill crystals, a separate currency from gems. Three known sources: Seen in footage · 2026-10-19
- Codes — the Update 3-5 waves handed out 31 free crystals (the codes tracker lists them); the store sells 10 for 450 Robux, which is exactly why the free ones matter. Seen in footage · 2026-10-07
- MVP Chests — a newer reward track: perform as the match MVP to earn MVP chests, which contain crystals. Dedicated farming guides focus on "how to get MVP every match" as the main loop — aggressive play that ends fights fast. Community report · 2026-10-25
- Battle Pass tiers — the Mongols pass paid crystals along its track; whether the next pass repeats the pattern is unverified. Community report · 2026-10-19
