Crystals are the premium currency of Summoners War: Sky Arena, Com2uS's RPG/strategy game. They're used to summon monsters through Summoning Scrolls (Mystical, Legendary and others), buy limited items in the Glory Shop, speed up construction, or acquire runes and pieces during special events. While they can be bought with real money, the game offers plenty of free ways to build them up if you play consistently. In this guide we cover the verified sources of free Crystals: Daily Missions, weekly Arena rewards, the Glory Shop, the Trial of Ascension, the Dimensional Rift, generator buildings like the Crystal Mine and Crystal Titan, plus the World Boss, achievements and the promo codes Com2uS publishes periodically. Nothing here is made up: everything comes from community guides and the game wiki, and it's clearly noted when a method depends on player performance or luck (RNG).
What's the fastest way to get Crystals in Summoners War?
We've gathered and verified every real method for getting free Crystals, ranked from most to least profitable based on the time they take and what you can actually earn from each. No tricks, no generators — just the game's own mechanics.
Daily missions
Completing daily missions is one of the simplest ways to get Crystals, since they refresh every day and don't depend on luck. According to community guides, they add up to around 50 Crystals a day, split across two batches of 25. The missions ask for basic actions like fighting in the Arena, summoning monsters or upgrading runes, things any active player naturally does. It's the foundation any F2P Crystal-farming strategy is built on.
Weekly Arena rewards
The Arena hands out Crystals every week based on the rank reached at season close. Reaching Conqueror 1 grants 150 Crystals, while reaching Legend can mean up to 750 Crystals weekly. On top of these rank rewards, beating opponents in individual Arena battles also grants small additional amounts. The more you compete and rank up, the higher the return, so this method especially rewards players who stay consistent in PvP.
Glory Shop (daily limited purchase)
Inside the Glory Shop there's a limited-purchase section that resets every day and includes 25 free Crystals available to claim. It's a passive method: just log in daily and grab the offer before it expires. Since it requires no combat effort, it pairs very well with the daily missions and should be part of the daily routine for any player looking to maximize their free Crystals.
Trial of Ascension
The Trial of Ascension is content that resets periodically, with rewards tied to floor progress on Normal and Hard difficulty. According to community guides, completing both modes can amount to around 1,500 accumulated Crystals, and Hell difficulty adds further rewards of about 50 Crystals per floor cleared. It requires a developed monster roster, so it becomes more relevant as your account progresses.
Dimensional Rift
The daily mission tied to the Dimensional Rift grants 3 Dimensional Crystals, which can stack up to a maximum of 10 before you redeem them for entries into the Rift itself. Although the daily amount is modest, being a guaranteed daily resource it helps sustain a steady flow of Crystals without relying on luck or competitive performance.
Generator buildings: Crystal Mine and Crystal Titan
Building and maintaining structures like the Crystal Mine or the Crystal Titan generates Crystals passively around the clock. The Crystal Mine produces 1 Crystal every 10 hours (about 2.4 a day), while the Crystal Titan produces 1 every 8 hours (about 3 a day). They need no daily interaction beyond collecting, making them a quiet but steady complement to the other methods.
Other sources: World Boss, achievements and promo codes
The World Boss offers a chance to get Crystals with each of its daily victories, though since it's probability-based, a fixed figure can't be guaranteed. Scenario, Cairos, Rift, Arena and Monster achievements award Crystals as a one-time reward upon completion, adding a meaningful one-off boost early in your account. Finally, Com2uS periodically publishes promo codes that include Crystals along with scrolls and other materials; it's worth checking them regularly since they tend to expire.
How much free Crystals can you get per month?
| Source | Estimated amount |
|---|---|
| Daily missions | ~50 |
| Glory Shop (limited purchase) | ~25 |
| Weekly Arena rewards | ~150–750 |
| Dimensional Rift (daily mission) | ~3 |
| Buildings (Crystal Mine + Crystal Titan) | ~5–6 |
| Trial of Ascension (Normal + Hard) | ~1,500 |
| Estimated total | ~4,600–7,300 Crystals per month |
Estimate built from community guides (not official Com2uS figures), adding up daily missions, the Glory Shop, Arena, Dimensional Rift, generator buildings and the Trial of Ascension. It doesn't include the World Boss (probability-based), achievements (one-time reward) or promo codes (irregular), which can add extra Crystals on top. The real range depends mostly on your weekly Arena rank, which can vary from 150 to 750 Crystals depending on your PvP performance.

Frequently asked questions
How often does the Trial of Ascension and its Crystal rewards reset?
The Trial of Ascension resets periodically alongside content updates, restoring floor progress across Normal, Hard and Hell difficulties. Each reset lets you claim the Crystals for cleared-floor milestones again, so it's worth checking the tower's status after each relevant game update.
Is it worth ranking up in the Arena just to get Crystals?
Yes, it's one of the highest-return methods: going from Conqueror 1 to Legend multiplies the weekly reward fivefold (from 150 to 750 Crystals), on top of the smaller amounts earned for each opponent you beat. If you're already investing time into building your Arena team, this is one of the most rewarding free methods.
Do Summoners War promo codes really give free Crystals?
Yes, Com2uS publishes codes fairly regularly (collaborations, anniversaries, events) that usually include Crystals along with scrolls and mana pieces. The amount varies with each code and it's not a steady method, so it's best combined with the daily and weekly sources rather than relied on alone.
