My Party is Grinding Tier List: Best Classes and Pets to Use!

Choosing the right class and pet can make a big difference in My Party is Grinding. Since this is an idle RPG, your party keeps fighting and earning rewards while you focus on other things. However, not every class has the same strengths, and some pets are much more useful than others depending on whether you want EXP, Coins, or better chest rewards.

This My Party is Grinding Tier List ranks all available classes and pets based on their overall usefulness, combat performance, survivability, and passive bonuses. Whether you are just starting out or trying to improve your late-game setup, this guide can help you decide which options are worth using.

What Do the Class Tiers Mean?

• S Tier classes are the strongest choices overall. They offer excellent skills, high effectiveness, and few major weaknesses, making them suitable for difficult content and late-game progression.
• A Tier classes are also very strong and can perform well in most situations. They may have certain weaknesses or require a more specific build compared with an S Tier class.
• B Tier classes can still be useful, particularly during the early stages. However, they have more noticeable weaknesses and generally fall behind the higher-ranked options as progression becomes harder.

My Party is Grinding Class Tier List

S Tier

• Assassin

A Tier

• Warrior
• Mage
• Archer

B Tier

• Knight

Which Classes Are S Tier?

Assassin

Assassin is currently the strongest class in My Party is Grinding because of its excellent damage output. Its biggest advantage is its ability to deal heavy single-target damage, making it especially useful against bosses and tougher enemies.

The class also has access to several skills that can deal Area of Effect damage. This means Assassin is not limited to fighting one enemy at a time and can still help clear groups during regular stage farming.

With the right equipment, Assassin can also become more durable than expected. While it is primarily designed around damage, a suitable gear setup can help it survive longer in difficult encounters.

Best for:

• Boss fights
• High-damage builds
• Late-game progression
• Single-target damage

Which Classes Are A Tier?

Warrior

Warrior is a reliable all-rounder that combines offensive power with good durability. This makes it one of the easier classes to use when you are still learning the game or building your first serious setup.

With suitable equipment, Warrior can be developed into a strong frontline character while still maintaining decent damage. Its main weakness is that you need the right gear to get the most out of both its defensive and offensive abilities.

Best for:

• Beginners
• Balanced builds
• Frontline combat
• General progression

Mage

Mage is a versatile option with access to different elemental attacks. This gives the class more flexibility when facing enemies with different weaknesses. Its Area of Effect skills are another major advantage. Mage can clear groups of enemies efficiently, which makes it useful when farming stages and grinding for progression. The downside is that Mage benefits heavily from proper build optimization. Without the right setup, its performance may not remain as strong during later stages.

Best for:

• AoE farming
• Element-based builds
• Groups of enemies
• Boss fights

Archer

Archer is a strong ranged DPS option that can deal considerable damage while staying away from enemies. This makes it useful for players who want an offensive playstyle without putting their character directly in the frontline.

The class can also make use of different elemental attacks depending on your equipment and build, giving it some additional flexibility. Its biggest weakness is low HP. As enemies become stronger in later stages, Archer can struggle to survive if it does not have enough defensive support.

Best for:

• Ranged DPS
• Offensive builds
• Safe damage dealing
• Elemental setups

Which Classes Are B Tier?

Knight

Knight is a simple and accessible option that works well during the early part of the game. It does not require a complicated build, and you can use it immediately without worrying about additional unlocking requirements.

However, Knight eventually starts to fall behind the other classes. Despite being designed around defense, its durability does not always reach the level you would expect from a dedicated tank.

Best for:

• Beginners
• Early-game progression
• Simple builds
• Players without stronger classes

What Do the Pet Tiers Mean?

S Tier pets provide the most valuable bonuses and are especially useful for boss farming, chest collection, and late-game progression.

A Tier pets are strong alternatives with useful EXP or Coin bonuses. They are excellent choices when you want to focus on a specific type of farming.

B Tier pets still provide worthwhile bonuses, but their numbers are lower than the higher-ranked options. They are useful while you are working toward better pets.

C Tier pets have smaller bonuses and are mainly useful during the early game. Once stronger alternatives become available, there is usually little reason to keep using them.

Which Pets Are S Tier?

Gold Dragon

Gold Dragon is the best pet for Boss Chest Drop farming. Its +0.1% Boss Chest Drop bonus is the highest among the listed pets, making it particularly valuable when you are repeatedly fighting bosses for better rewards.

Boss chests can become increasingly important as you progress into harder content, so Gold Dragon remains useful even after the early game.

Bonus:

• Boss Chest Drop +0.1%

Best for:

• Boss farming
• Rare loot
• Late-game progression

Silver Dragon

Silver Dragon provides a +0.06% Boss Chest Drop bonus. While it does not match Gold Dragon, the bonus is still strong and makes it a good choice for players who are focused on boss rewards.

Since boss chests can contain useful equipment and resources, this passive continues to have value throughout progression.

Bonus:

• Boss Chest Drop +0.06%

Best for:

• Boss rewards
• Gear farming
• Chest farming

Red Dragon

Red Dragon focuses on regular chest farming with a +0.06% Normal Chest Drop bonus.

This makes it a strong choice for players who spend a lot of time clearing normal stages and collecting regular chests. Unlike boss-focused pets, Red Dragon is better suited to general stage farming.

Bonus:

• Normal Chest Drop +0.06%

Best for:

• Normal chest farming
• General loot
• Stage grinding

Which Pets Are A Tier?

Griffin

Griffin provides +2.5% Coin Gain, making it one of the best pets for players who need more currency.

The additional Coins can help you purchase classes and invest in your Orb Circuit upgrades. Its only major drawback is that it does not provide an EXP or chest-related bonus.

Bonus:

• Coin Gain +2.5%

Best for:

• Coin farming
• Orb Circuit upgrades

Alicorn

Alicorn also provides +2.5% Coin Gain. This makes it another excellent option for players who want to maximize their currency income.

It does not increase EXP or chest drops, so players focused on those rewards may prefer another pet.

Bonus:

• Coin Gain +2.5%

Best for:

• Coin farming
• General upgrades

Fenrir

Fenrir increases EXP Gain by +2.5%. This is useful when your main goal is leveling your classes as quickly as possible.

Its value is highest when EXP is limiting your progression. Once leveling is no longer your main concern, its passive becomes less important.

Bonus:

• EXP Gain +2.5%

Best for:

• EXP farming
• Class leveling

Phoenix

Phoenix has the same +2.5% EXP Gain bonus as Fenrir. It is another strong choice for players who repeatedly clear stages to level their classes.

However, it does not improve Coin income or chest rewards, making it less useful for players who have already finished their main leveling grind.

Bonus:

• EXP Gain +2.5%

Best for:

• Leveling
• EXP farming

Black Dragon

Black Dragon provides +2% Coin Gain, which is useful for players who are constantly spending currency on upgrades.

It ranks below Griffin and Alicorn because its bonus is lower at 2% instead of 2.5%, but it is still a solid choice for Coin-focused builds.

Bonus:

• Coin Gain +2%

Best for:

• Coin farming
• Orb Circuit upgrades

Which Pets Are B Tier?

Blue Dragon

Blue Dragon gives +2% EXP Gain, making it a useful leveling pet when stronger EXP options are not available.

Its main disadvantage is that the bonus is lower than the +2.5% provided by Fenrir and Phoenix.

Bonus:

• EXP Gain +2%

Best for:

• EXP farming
• Leveling

Green Dragon

Green Dragon provides +1.5% EXP Gain. This can still help during regular progression, although stronger EXP-focused pets become much better once you have access to them.

Bonus:

• EXP Gain +1.5%

Best for:

• EXP grinding
• Early progression

Bronze Dragon

Bronze Dragon offers +1.5% Coin Gain. This is useful during the early stages when you need additional currency for upgrades.

However, its bonus is weaker than Black Dragon’s 2% and the 2.5% bonus offered by Griffin and Alicorn.

Bonus:

• Coin Gain +1.5%

Best for:

• Early Coin farming
• General progression

Spirit of Earth

Spirit of Earth increases Boss Chest Drop by +0.04%. This is a useful bonus if you are already spending time fighting bosses, but the percentage is noticeably lower than the 0.06% and 0.1% options.

Bonus:

• Boss Chest Drop +0.04%

Best for:

• Early boss farming
• Boss rewards

Spirit of Wind

Spirit of Wind gives +0.04% Normal Chest Drop. It can help increase your rewards while farming regular stages, but Red Dragon offers a stronger +0.06% bonus.

Bonus:

• Normal Chest Drop +0.04%

Best for:

• Normal chest farming
• Early progression

Which Pets Are C Tier?

Flame Spirit

Flame Spirit provides +1% EXP Gain. This is helpful for new players who are still leveling their classes, but the bonus is relatively small compared with the stronger EXP pets.

Bonus:

• EXP Gain +1%

Best for:

• Early-game leveling

Spirit of Water

Spirit of Water provides +1% Coin Gain. The extra currency can help during the beginning of your progression, but the bonus becomes less attractive once you obtain stronger Coin-focused pets.

Bonus:

• Coin Gain +1%

Best for:

• Early Coin farming
• New players

Night Dragon

Night Dragon increases Normal Chest Drop by only +0.01%. While any additional chest chance can be useful, this bonus is considerably lower than Spirit of Wind and Red Dragon.

Bonus:

• Normal Chest Drop +0.01%

Best for:

• Very early chest farming
• Early progression

Best Classes and Pets in My Party is Grinding

If you want the simplest answer, Assassin is the best overall class in this tier list thanks to its strong single-target damage, useful AoE skills, and good performance in difficult content. For pets, Gold Dragon is the top choice for boss chest farming, while Red Dragon is better when you spend most of your time collecting normal chests. If you need more currency, Griffin or Alicorn are excellent choices because of their +2.5% Coin Gain.

For leveling, Fenrir and Phoenix are the strongest options because of their +2.5% EXP Gain. Keep in mind that the best choice can change depending on what you are currently trying to farm. A pet that ranks lower overall can still be the better option if its passive matches your immediate goal.
