Common Summoners War Mistakes and How to Avoid Them

Written by Rumbi

April 30, 2026

Progressing in Summoners War can feel slow if you fall into common traps that waste resources and delay your growth. Many players make the same early- and mid-game mistakes—but the good news is they’re easy to fix once you know what to look for. This guide breaks down the most frequent errors and shows you how to avoid them.

Why These Mistakes Matter

Every resource in Summoners War—Crystals, Devilmon, Runes, and time—is valuable. Misusing them can set your progress back significantly. By focusing on efficient farming, smart upgrades, and proper team building, you can accelerate your progression and compete more effectively.

Top 10 Common Mistakes & Solutions

1. Wasting Crystals on Summoning

Mistake: Spending Crystals on Premium Packs.
Solution: Use Crystals for Energy refills instead. Farming dungeons gives you better long-term value through Runes and monster drops.

2. Misusing Devilmon

Mistake: Feeding Devilmon to 3★ or most 4★ monsters.
Solution: Save Devilmon for Natural 5★ monsters or a few key 4★ units that are essential for progression.

3. Ignoring Fusion & Farmable Units

Mistake: Overlooking powerful free monsters.
Solution: Build key units like Veromos (Dark Ifrit), Fran (Fairy Queen), and Loren (Light Cow Girl). These are essential for early and mid-game success.

4. Ignoring Rune Quality

Mistake: Keeping low-quality runes or flat-stat main stats.
Solution: Focus on 5★–6★ runes with % stats on slots 2/4/6. Sell weak runes to save space and mana.

5. Six-Starring Too Many Monsters

Mistake: Building too many units too early.
Solution: Prioritize a strong PvE team for Giants and Dragons before expanding into PvP units.

6. Skipping Daily and Weekly Tasks

Mistake: Ignoring missions and guild shop rewards.
Solution: Complete daily tasks and buy important items like Devilmon weekly.

7. Neglecting Artifacts

Mistake: Not farming Artifact dungeons.
Solution: Artifacts provide extra stats like HP and damage—don’t skip them.

8. Not Using Friends’ Representatives

Mistake: Playing solo without support units.
Solution: Use powerful friend reps to clear tough stages and speed up progression.

9. Selling Potentially Good Runes

Mistake: Selling runes without testing them.
Solution: Upgrade runes to +3 or +6 to check substat rolls before deciding.

10. Avoiding Guilds

Mistake: Not joining a guild early.
Solution: Participate in Guild Wars and Siege battles to earn points for valuable rewards like summoning pieces and Rainbowmon.

Key Tips to Avoid These Mistakes

Follow the Summoner’s Way Path

The Summoner’s Way quests guide your progression and provide excellent rewards. Stick to this path to stay on track.

Use the Repeat Battle Feature

Farm efficiently in the background while doing other tasks. This helps you maximize your time and resources.

Prioritize PvE First

Your first major goal should be a stable Giants B10/B12 team. After that, move on to Dragons and Necropolis.

Lock Important Monsters

Always lock valuable monsters like Natural 5★ units to avoid accidentally feeding them.

Check Rune Rolls Carefully

Test runes at +3, +6, and +9 before committing to full upgrades. This saves mana and helps you keep only the best gear.

Even experienced Summoners War players occasionally make small mistakes that can cost valuable progress. Two of the most damaging—and surprisingly common—errors are feeding the wrong monsters and missing out on in-game events. Understanding these pitfalls can save you time, resources, and frustration.

Feeding the Wrong Monster Away

Why It’s a Problem

In Summoners War, monsters are often used as material to power up or evolve others. However, not all monsters are expendable. Accidentally feeding away a rare or useful unit—especially a Natural 4★ or 5★—can permanently set you back. Some monsters are difficult (or impossible) to replace quickly, and others may seem weak at first but become valuable later.


Common Causes

  • Not knowing a monster’s long-term value
  • Using auto-select carelessly when powering up
  • Failing to lock important units
  • Assuming duplicates are useless

How to Avoid It

1. Lock Valuable Monsters Immediately
As soon as you summon a Natural 4★ or 5★ monster—or any unit you’re unsure about—lock it. This prevents accidental use as material.

2. Learn Which Monsters Are Worth Keeping
Even some 3★ monsters are extremely useful for PvE content. Research or follow progression guides before feeding anything away.

3. Be Careful with Auto-Select
Always double-check what the game selects when upgrading monsters. Auto-select can include units you didn’t intend to use.

4. Keep One Copy of Each Monster
Even if a monster seems weak now, future balance patches or content may make it valuable.

Missing Out on Events

Why It’s a Problem

Events in Summoners War are one of the best sources of free rewards, including Crystals, Devilmon, scrolls, and even powerful monsters. Skipping events means missing out on resources that could significantly boost your progress.


Common Causes

  • Not checking the Events tab regularly
  • Assuming events aren’t worth the effort
  • Playing inconsistently or logging in infrequently
  • Overlooking limited-time rewards

How to Avoid It

1. Check the Events Tab Daily
Make it a habit to review active events every time you log in. Many require simple tasks like using energy or completing dungeons.

2. Prioritize Easy Rewards First
Focus on events that align with your normal gameplay—like farming or daily missions—so you earn rewards without extra effort.

3. Log In Consistently
Even if you don’t have time to play extensively, logging in daily can secure valuable login rewards.

4. Plan Around Big Events
Special events often offer the best rewards. Save resources like energy or crystals so you can fully participate when they appear.

Avoiding these common mistakes will dramatically improve your progress in Summoners War. Focus on efficient farming, smart resource management, and building a solid PvE foundation. With the right approach, you’ll advance faster and build stronger teams without wasting valuable resources.
