How Many XP Books Do You Need to Reach Level 90 in Genshin Impact?

Do you really plan to put in some efforts?

By Robert Gaskins

Reaching level 90 in Genshin Impact means you should be ready to go a long way with a hefty stash of XP books in your pocket. The amount depends on how many characters you plan to level up. Here’s what you need, the best methods to collect these resources, and tips to make the whole process easy and manageable.

Total XP Needed to Genshin Impact Reach Level 90

To max out a character at level 90, you’ll need approximately 8,362,650 XP points. This figure translates into a large number of Hero’s Wit books, the highest-tier XP book in the game, as well as some lesser XP books if you’ve accumulated those along the way.

  • Hero’s Wit (purple) – Gives 20,000 XP per book. You’ll need around 421 Hero’s Wit to go from level 1 to 90.
  • Adventurer’s Experience (blue) – Provides 5,000 XP per book. If you only used Adventurer’s Experience, it would require around 1,673 books.
  • Wanderer’s Advice (green) – Provides 1,000 XP per book. For Wanderer’s Advice, you’d need about 8,363 books.

Hero’s Wit books are by far the most efficient way to level up in Genshin Impact due to their high XP value, saving you both time and effort.

Do You Really Need to Unlock Level 90?

For most DPS units, you obtain only minimal boosts in stats to go from level 89 to 90—usually just a slight increase in attack points. However, support characters that rely on HP or defense stats and Anemo characters (for Swirl reaction damage) get the best benefits from leveling up in the game.

Tip: To reach a DPS character to 90, consider stopping at level 89. This saves you 28 Hero’s Wit books, which can then be used for another character.

The Best Ways to Farm XP Books in Genshin Impact

The primary way to get XP books, specifically Hero’s Wit, is through Blossoms of Revelation. Here’s how it works:

  1. Find Blossoms of Revelation – These are marked by a light blue sphere on the map and can be accessed once you reach Adventure Rank 12.
  2. Complete the Blossom Challenge – Defeat nearby enemies so you can interact with the Blossom again and claim your XP books. Each Blossom challenge costs 20 Resin.
  3. Use Condensed Resin – Condensed Resin, crafted with Crystal Cores and Resin, allows you to claim double rewards from a Blossom. It’s a quick way to fill up more books in your inventory with fewer runs but one costs 40 Resin.

World Level Impact on Book Farming

Hero’s Wit becomes available as you increase your World Level. Here’s the breakdown:

  • World Level 4: Two to three Hero’s Wit per Blossom
  • World Level 6-8: Up to four to five Hero’s Wit per Blossom

Higher World Levels mean stronger enemies, so balance the risk with the rewards you can gain based on your current strength.

How to Stockpile XP Books Easily

It takes time to farm a big chunk of experience point books since Resin, the resource needed to claim rewards from Blossom challenges, has a daily cap. To get the most out of your farming, save Fragile Resin for double XP events or days when you have extra time to do multiple Blossom challenges in a row. These items will refill your Resin instantly so it’s perfect for quick farming sessions.

Another way to do it is to plan around Resin refresh times. Resin regenerates over time so checking in periodically to use any replenished one will prevent you from wasting it and keep you stocked with XP books. Further, many events in Genshin Impact reward Hero’s Wit; keep an eye on them to stockpile more Wits for character leveling. With these in mind, managing your resources becomes much easier and you can stockpile more for future character level-ups.
