Ranking up in Diverse Piece is one of the main progression systems that unlocks stronger weapons, skills, and special characters like Stark, Eizen, Gojo, and Sukuna. For new players, the process might seem simple, but ranking efficiently can save you a lot of time and effort. This guide will explain how to rank up from F Rank all the way to S Rank quickly, including tips to speed up your progress and what you’ll need to prepare beforehand.
Understanding the Ranking System
When you first start in Diverse Piece, you begin at F Rank, the lowest tier. Your goal is to work your way up through multiple ranks — each one representing your overall combat progress and experience. Currently, there’s only one main way to increase your rank, and that’s through missions.
Ranking up is important because higher ranks not only unlock exclusive titles but also give you access to stronger items and boss fights. Some top-tier weapons and specs require S Rank, making this a key milestone in your journey.
Step 1: Unlocking Missions at Wano Island

Head to Wano Island, the main hub for ranking missions. On top of the area, you’ll find the Missions NPC. Talking to this NPC gives you random boss missions. You can keep interacting with them until you receive a mission you want to take on.
Each mission gives two major rewards upon completion:
- Shards – used to purchase or craft high-level items.
- Rank Experience – progresses you toward the next rank.
To rank up fast, repeat boss missions continuously. Focus on completing them quickly rather than switching between different types of quests.
Step 2: Target Specific Bosses for Efficiency
Not all bosses are available at the same time. If some are missing, take whichever one is currently spawned. For example, Eizen is often one of the more reliable bosses to find. Keep farming Eizen until more bosses spawn. The key is constant mission completion—don’t waste time waiting for a specific enemy.
Using powerful weapons or specs helps you clear bosses faster. The Rudo spec, for example, is an easy-to-get and effective choice for dealing consistent damage. Pair it with Light or other strong DPS options to clear missions quickly.
Step 3: When to Start Focusing on Ranks

You should only start grinding for ranks after reaching max level. Before that, your main goal should be leveling up and unlocking skills. Once you’re maxed out, shift your focus to mission grinding for ranking progress. Doing so ensures you can clear bosses faster and handle harder missions without much trouble.
Step 4: From F to S Rank Progression
As you complete missions, your rank will rise gradually — F → E → D → C → B → A → S. Each step may require more missions and stronger bosses, so the grind gets tougher near the end. Keep a balanced setup and work with friends to speed things up, especially during boss respawns.
Currently, ranking up doesn’t provide buffs, but it’s a requirement for unlocking exclusive content. Once you hit S Rank, you’ll be able to access high-tier content like Stark and Eizen weapons.
Tips to Rank Up Faster
- Farm bosses continuously – Don’t stop between missions; accept new ones immediately.
- Join friends or public lobbies – Faster boss clears mean faster rank progression.
- Use strong weapons/specs – Rudo, Light, or meta weapons make fights much smoother.
- Don’t wait for specific bosses – Complete whatever missions are available.
- Focus after max level – You’ll save time and gain rank EXP faster.
Ranking up in Diverse Piece may take time, but with the right setup and strategy, reaching S Rank is completely achievable. Missions are the main source of rank EXP, so consistency is the key. Once you hit S Rank, you’ll unlock access to endgame bosses, powerful weapons, and rare items that define your progress in the game. Keep grinding, stay efficient, and you’ll climb the ranks faster than you think.
