What To Do Next
Leveling Guide
Leveling route, Monster Album progression, gear milestones, party gap rules, and experience boosts.
Welcome to the Serein MMO Leveling Guide. This guide explains the recommended leveling path from Level 1 to the current maximum level, including where to level, when to upgrade your gear, how to use the Monster Album system, and which experience boosts can help you progress faster.
Important Leveling Information
- Having a low-level leech character follow you will no longer give bonus experience.
- Leeching is not required for efficient leveling.
- Players may still level up two characters together by using Party Mode [Level].
- Party level gap restrictions begin when there is a 19 level difference or higher between party members.
Monster Album System

Unlocking Monster Album entries can grant:
- Permanent stat bonuses
- Useful item rewards
- Better long-term progression for your character
Gear Progression
Using proper gear while leveling will make your progression much smoother. It is recommended to update your equipment at the following level milestones:
Updated gear increases your attack and defense, which helps you kill monsters faster and survive more easily. If your desired weapon or armor does not drop directly, monsters can also drop Weapon Pieces and Armor Pieces. These pieces can be used to craft your desired equipment.
Recommended Leveling Path
Follow the route cards below in order. Each route shows the recommended area, level range, and monster order. Try to unlock Monster Album entries as you progress instead of leaving them all for later.

The Awakening System is a gear-enhancement system that allows players to add extra awake stats to their equipment. Awakes can improve damage, survivability, speed, utility, and other useful character stats.
Wiki Awakenings
Before spending scrolls, players can check possible awakening stats, chances, and values from the in-game Wiki Awakenings page.
What Can Be Awakened?
Different item types require different awakening scrolls. Click any scroll below to view where it is obtained.
Weapons, Shields, Armor, Raised Pets
These items use Scroll of Awakening or Super Scroll of Awakening.
Fashion, Masks, Wings, Cloaks
These items are awakened with Blessing of the Goddess.
Looter Pets and Catched Giants

Awakening Line Limits
NPC and Scroll Sources
How Manual Awakening Works

Summary Box
The summary box combines similar awakened stats so players can quickly understand the total result.
Awakening Modes
Manual Awakening
Use this when you want to awaken one attempt at a time and manually decide whether to keep or replace the result.

Awakening Tips
- Use Wiki Awakenings first to understand possible stats, values, and chances.

- Use Auto Awakening carefully because it keeps consuming scrolls until your selected condition is reached.
- Use Super Scroll of Awakening when you want better chances and at least 2 lines on eligible items.
- Fashion-type items can only reach 1 awakening line, so choose your target carefully.
Gear Score Guide
How Gear Score works, where to see it, which items count, and how to calculate your estimated total.
Gear Score is a progression value based on the equipment your character is wearing. It helps players understand the overall strength of their gear and is also used as an entry requirement for dungeon access.
How Gear Score Appears in Tooltips
Gear Score items show their base value and bonus value separately. The base value comes from the item itself, while the bonus value comes from upgrades and piercing.
Why Gear Score Matters
Dungeon Entry
Gear Score is required to unlock access to certain dungeon entries. Higher-level or harder dungeons may require a higher total Gear Score.
Gear Progression
Gear Score gives players a quick way to judge if their current equipment is strong enough for the next stage of progression.
Teleporter Check
Players can check the minimum Gear Score required to enter a dungeon through the Teleporter system [V].
Equipment That Gives Gear Score
Gear Score is calculated from specific equipment slots only.
Gear Score Formula
Every Gear Score item has a base Gear Score value set on the item. The final value is calculated by adding the base Gear Score, upgrade bonus, and piercing bonus together.
Weapon Upgrades
+1.0 Gear Score per upgrade level.
Example: Weapon +20 = +20 Gear Score.Armor / Shield Upgrades
+0.2 Gear Score per upgrade level.
Example: Shield +10 = +2 Gear Score.Jewelry Upgrades
+0.1 Gear Score per upgrade level.
Example: Ring +20 = +2 Gear Score.Piercing
Suit: +1.0 per pierce slot, up to 4 slots. Weapons and Shields: +0.5 per pierce slot.
Only opened pierce slots are counted. Off-hand weapons count piercing only.Interactive Gear Score Calculator
Use this calculator to estimate your total Gear Score. Enter the base Gear Score shown in your item tooltip, then select the upgrade level and pierce slots where applicable.

| Ring 1Max +20 | — | 0.0 | ||

How To Improve Gear Score
- Equip items with higher base Gear Score.
- Upgrade your main weapon because weapon upgrades give the highest upgrade bonus.
- Upgrade armor and shields for steady Gear Score gains.
- Upgrade jewelry after your main weapon and armor are stable.
- Open pierce slots on your suit, weapons, shields, and off-hand weapon when available. Suit piercing can add up to +4 Gear Score.
