Gems Guide - Command An Army Wiki
Where gems come from, what they are worth, and how to spend them so every drop of income turns into a stronger army.
Overview
Gems are the premium currency in Command An Army, the resource you pour into summons and upgrades to build a stronger force. You earn them from match payouts, quests and every redeemable code, then spend them on new troops and class changes. Start with active codes for a free boost.
This guide explains both halves of the gem economy: where steady income comes from and where it should go. Knowing the difference between spending that compounds and spending that evaporates is what separates a fast-growing army from one stuck in place. Pair it with Create a Better Army.
Watch Gems Earned and Spent
A full walkthrough of earning and spending gems in practice, from redeeming codes in the first minute to summoning your first stronger troops. Watching the flow once makes the rest of this guide obvious. Follow it with How to Get Gems Fast for a repeatable daily routine.
Where Gems Come From
You earn gems from three places: finishing matches, clearing quests, and redeeming codes. Match wins pay out gems directly, quests hand over a dependable drip for objectives you complete anyway, and codes are the fastest one-time hit. Grab every active codes reward before you grind anything else.
Quest gems are the quiet workhorse of the economy. They reward the same recruiting, capturing and battling you already do, so a player who checks quests every session out-earns one who only chases wins. Treat match rewards as a bonus rather than your whole plan, and see the Beginner Guide for the core loop.
Buying gems with Robux is always optional. The developers do not hide progression behind a paywall, so codes plus steady quests cover everything a growing commander needs. If you never plan to spend real money, this guide still gets you to the same upgrades, just a little slower. Check How to Get Gems Fast for pacing.
Gem Sources Compared
This table ranks each way to earn gems by how much effort it takes and how reliable it is. Codes are the fastest but finite, quests are steady, and matches scale with how often you play. Use it to decide where to spend your time each session. New players should read the Beginner Guide first.
Expect the exact payouts to shift with each patch, so treat any number here as a rough guide rather than gospel. What stays constant is the order: redeem codes first, keep quests rolling, then farm matches for the rest. Cross-check totals against active codes whenever a new update drops.
| Source | Effort | Reliability |
|---|---|---|
| Codes | Very low - type a password once | One-time, expires over time |
| Quests | Low - completes as you play | High and repeatable |
| Match wins | Medium - depends on results | Scales with playtime |
| Robux bundles | Instant but costs money | Guaranteed, optional |
How to Spend Gems Well
Spending matters as much as earning. Follow this order so your gems compound instead of trickling away on cosmetics or panic level-ups. The goal is always the same: turn currency into a permanently stronger army. If you are early on, the Beginner Guide sets the context.
Redeem codes first
Claim every working code before spending anything, so you spend with a bigger budget in hand.
Summon core units
Put gems into summons that fill your frontline and ranged roles rather than chasing rare pulls.
Upgrade what you field
Level and evolve the troops you actually equip every match instead of a wide shallow roster.
Save for ascension
Once your core units are evolved, bank gems for ascension, the biggest long-term power gain.
Avoid cosmetics early
Skip skins and non-combat extras until your core army is fully upgraded and winning regularly.
Smart Spending Priorities
Think of gems as fuel for a single engine: your fielded army. Every purchase should make the troops you actually deploy stronger, faster or cheaper to run. Broad spending across many units spreads your currency thin and leaves you with nothing dominant. See Best Units to target the right picks.
If two choices look similar, pick the one that helps in more situations. A frontline upgrade that survives longer usually beats a flashy summon you rarely field. Over many matches, small compounding advantages decide more fights than any single lucky roll. Pair this with Create a Better Army for the full picture.
Core Summons
Fill frontline and ranged roles before you chase anything rare or flashy.
Level Ups
Raise the troops you field every match so the gain shows up in every round.
Evolution
Evolve core units to unlock stat jumps bigger than a plain level upgrade.
Ascension
Bank gems for ascension once your core army is evolved and stable.
Gem Economy Checklist
Run this list each session to keep your income healthy and your spending disciplined. It takes a minute and stops the small leaks that quietly drain a gem balance over a week. Everything here works whether you play daily or a few times a week. Keep active codes bookmarked so you never miss a drop.
- Redeem every active code the day it appears.
- Pick up quest gems before grinding extra matches.
- Summon only to fill a real role gap in your loadout.
- Upgrade and evolve the troops you field most.
- Bank a reserve for ascension instead of impulse spending.
- Skip cosmetics until your core army is fully upgraded.
Frequently Asked Questions
What are gems used for in Command An Army?
Gems are the premium currency, spent on summoning new units, upgrading and evolving your troops, and changing your commander class. They power the whole long-term progression path.
How do I earn gems without paying?
Finish matches, clear quests and redeem active codes. Those three sources cover almost everything a growing commander needs, and none of them require Robux.
Should I buy gems with Robux?
Only if you want to skip the grind. Every upgrade path here is reachable through normal play, quests and redeemed codes, so buying gems simply speeds up progression you can earn anyway.
What should I spend gems on first?
Your core units. Fund summons that fill frontline and ranged roles, then upgrade and evolve the troops you equip every match before you chase anything rare or cosmetic.
Do gems carry between matches?
Yes. Your gem balance is permanent account progress, not a per-round resource. Anything you buy with gems, like a unit upgrade, stays with you for every future match.
Why did my code give no gems?
Codes are case-sensitive and expire without warning. Recheck the spelling, and if it still adds nothing, that code has likely lapsed - see active codes for the current list.
