Character EXP Books are essential for leveling up characters in Genshin Impact, but they can disappear quickly when building multiple characters. Since every new character requires a large amount of experience materials, knowing the best ways to farm EXP Books will help you progress more efficiently.
The most reliable way to farm EXP Books is by completing Blossom of Revelation Ley Line Outcrops. These challenges appear throughout Teyvat and reward Character EXP Materials after spending Original Resin. They can be repeated as often as needed, making them the best option when you run low on Hero’s Wit and other EXP items.
Events are another excellent source of free EXP Books. Limited time events frequently reward players with Hero’s Wit, Mora, Primogems, and other useful materials. Completing these events whenever they are available is one of the easiest ways to build up a large supply without spending Resin.
Exploration and quests can also provide a surprising amount of EXP Materials. Opening chests, completing World Quests, leveling up regions, and progressing through the story will reward various resources that can help you level characters without additional farming.
To avoid wasting EXP Books, focus on upgrading the characters you actually plan to use. Leveling every character immediately can quickly drain your resources, so prioritize your main damage dealers or the ones that are your personal favorites that you plan on using often.
