In the world of mobile gaming,Summoners Warstands out as one of the most complex and rewarding strategy RPGs ever created. Players around the globe spend countless hours enhancing their monsters, improving runes, and perfecting their teams. One of the most important aspects of the late game is grindstone farming, a process that allows players to upgrade their rune stats beyond normal limits. Understanding how Summoners War grindstone farming works can dramatically improve your monsters’ performance and help you compete more effectively in PvE and PvP modes alike.
What Is a Grindstone in Summoners War?
A grindstone inSummoners Waris a special item that enhances rune substats by adding additional value to them. It is primarily used to make powerful runes even stronger. For example, a grindstone can add extra attack, defense, or speed to a rune’s substats, giving your monster a noticeable boost in combat. Grindstones are particularly valuable for improving six-star legendary runes that already have strong base stats.
Each grindstone is tied to a specific rune set type, such as Violent, Swift, Rage, Despair, or others. This means you can only use a particular grindstone on a rune that matches its set. For instance, a Violent grindstone cannot be used on a Swift rune. This system encourages players to farm specific dungeons depending on what type of runes they prefer to use.
How to Obtain Grindstones
1. Rift Beasts
One of the main sources for grindstones inSummoners Waris the Rift Beasts. These battles are located in the Rift of Worlds and feature different elemental beasts Fire, Water, Wind, Light, and Dark. By defeating these bosses, players can earn grindstones and enchant gems that correspond to different rune sets. For example, the Fire Beast may drop grindstones for Fatal or Rage runes, while the Water Beast might provide Energy or Swift ones.
2. Rift Raid (R5)
High-level players often spend a lot of time farming Rift Raid level 5, commonly known as R5. This is the most efficient source for grindstones because it offers high-tier drops, including Hero and Legendary grade grindstones. In addition, R5 gives players a chance to obtain grindstones for sets that are extremely popular in competitive play, such as Violent and Will. Teaming up with friends or guild members makes R5 farming faster and more consistent.
3. Events and Special Rewards
Occasionally, Com2uS the developer ofSummoners Warruns events that provide grindstones as part of the rewards. These can include login events, anniversary events, or crafting material bonuses. Smart players take advantage of these opportunities to gather grindstones without having to farm energy-intensive dungeons.
Types of Grindstones
Grindstones come in several grades and types, each with different effects on runes. Understanding these differences can help you make the best use of your resources.
- Normal GrindstoneAdds a small stat increase; best for early-game use.
- Hero GrindstoneProvides a higher boost to substats; ideal for mid-game players.
- Legendary GrindstoneOffers the biggest improvement; used for top-tier runes in late game.
Each grindstone also targets specific stats. There are grindstones for Attack, Defense, HP, Speed, Critical Rate, Critical Damage, and Accuracy or Resistance. Choosing the right grindstone depends on your monster’s role attackers benefit from Attack and Crit Damage boosts, while supports may prefer HP and Resistance increases.
How to Use Grindstones Effectively
1. Choose the Right Rune
Using grindstones on weak or temporary runes is a waste of valuable resources. Focus on high-quality six-star runes that have desirable main stats and substats. For instance, a Violent rune with Speed, HP%, and Crit Rate is worth enhancing with grindstones, as those stats directly improve your monster’s combat ability.
2. Grind the Correct Substat
Not every substat should be grinded. Only grind those that significantly benefit your monster’s build. For example, on a DPS monster, Attack, Crit Rate, and Speed are priority stats. On a tank or healer, HP and Defense are usually better. Avoid grinding unnecessary stats like Resistance on a damage dealer unless it’s part of a specific strategy.
3. Don’t Overuse Grindstones
Grindstones are valuable and sometimes rare. It’s best to save Legendary grindstones for runes that are part of your main team or PvP setup. Using lower-tier grindstones on temporary runes is fine early on, but as you progress, focus your resources on the best equipment.
Farming Strategies for Grindstones
1. Building an Efficient R5 Team
Since Rift Raid level 5 is the most consistent source of high-quality grindstones, building an effective R5 team is essential. A good R5 team includes
- A cleanser like Delphoi or Riley to remove debuffs.
- A reliable healer such as Fran or Colleen.
- Damage dealers like Kro or Hwa for consistent output.
- A defense breaker like Loren to maximize damage potential.
Having the right balance of support and damage ensures faster runs and better drop rates. Team synergy also affects the quality of grindstones obtained, as higher performance scores lead to better loot boxes.
2. Auto-Farming During Events
During energy discount or drop rate increase events, it’s smart to farm grindstones as much as possible. Using auto-repeat battles helps maximize efficiency while minimizing manual effort. Many players run R5 or Rift Beasts overnight or while doing other activities to accumulate a steady supply of grindstones.
3. Focus on Specific Elemental Beasts
If you need grindstones for particular rune sets, target the right elemental beasts. For example
- Fire Beast Rage and Fatal grindstones (good for damage dealers)
- Water Beast Swift and Energy grindstones (ideal for supports)
- Wind Beast Blade and Guard grindstones (balanced rune sets)
- Light Beast Violent and Will grindstones (best for PvP)
- Dark Beast Nemesis and Shield grindstones (good for hybrid builds)
This focused approach saves time and ensures you collect grindstones that match your most-used rune sets.
Crafting Grindstones
In addition to farming, players can also craft grindstones using materials obtained from Rift Beasts and Raids. The crafting system allows you to select specific rune types, but the result is still random in terms of stat and grade. Crafting is an excellent option when you have excess materials or want to target rare sets like Violent or Will. However, since crafting can consume many materials, it’s wise to do it selectively rather than frequently.
Common Mistakes to Avoid in Grindstone Farming
- Farming Without a GoalAlways know which rune sets you want to improve before farming; random farming wastes energy and time.
- Using Grindstones on Low-Quality RunesAvoid enhancing runes that you will soon replace.
- Ignoring Team OptimizationA poorly built R5 team will result in slower runs and fewer high-quality grindstones.
- Not Saving High-Grade GrindstonesLegendary grindstones should be reserved for the best possible runes.
Long-Term Benefits of Grindstone Farming
Consistent grindstone farming has massive long-term advantages. It allows you to fine-tune your monsters’ stats and gain a competitive edge in various game modes such as Arena, Guild Wars, Siege Battles, and Dimensional Hole content. Players who regularly farm grindstones eventually build superior rune sets that can outperform even those with similar base runes.
Additionally, grindstones help bridge the gap between mid-game and late-game players. While early players may rely on basic runes, grindstones offer the flexibility to gradually enhance those runes until better ones are available.
InSummoners War, mastering grindstone farming is one of the most effective ways to strengthen your monsters and push your account to new heights. By understanding where to find grindstones, how to use them effectively, and which rune sets to focus on, you can make steady and meaningful progress. Whether you’re raiding Rift Beasts, teaming up for R5, or crafting grindstones through the crafting system, consistency is key. Over time, these enhancements will make your monsters faster, stronger, and more durable giving you a real advantage in every battle. Grindstone farming may take patience, but the rewards are well worth the effort for any dedicated Summoners War player.
