Genshin Character EXP Guide: XP Books, Level 1-90 Costs & Farming Plan

Character EXP looks simple - fight, farm, feed books - but the real bottleneck is XP books. Taking one character from level 1 to 90 costs 8,362,650 EXP, roughly 418 Hero's Wit, and the final ten levels alone eat 171 of them. This guide covers where EXP comes from, how efficient Blossom of Revelation is, and whether to stop at 80 or push to 90.

Three Kinds of XP Book

Character EXP comes from XP books in three tiers:

Name	EXP per Book	Tier
Hero's Wit	20,000	Purple (highest)
Adventurer's Experience	5,000	Blue
Wanderer's Advice	1,000	Green

Spend the higher tiers first, but do not throw away the lower ones - they are handy for topping off the last bit of EXP.

EXP Requirements from 1 to 90

Breaking the grind into segments makes the final spike obvious:

Range	EXP Needed	Hero's Wit (Approx)	Mora
1 to 20	120,175	6	24,200
20 to 40	578,325	29	115,800
40 to 50	579,100	29	116,000
50 to 60	854,125	42	171,000
60 to 70	1,195,925	58	239,200
70 to 80	1,611,875	81	322,400
80 to 90	3,423,125	171	684,800
Total	8,362,650	About 418	1,673,400

The last ten levels take 40% of the total EXP and 171 books, which is exactly why the 80 versus 90 debate exists.

Blossom of Revelation: The Main Source

Blossom of Revelation (the blue ley line) unlocks at Adventure Rank 12 and costs 20 resin per claim, scaling with World Level. At World Level 6 and above it gives about 4-5 Hero's Wit plus 6-7 Adventurer's Experience, totaling around 110,000-135,000 EXP (about 5,500-6,750 EXP per resin).

That means one character from 1 to 90 takes roughly 70-76 max-level runs, or 1,400-1,520 resin, close to 9-10 days of natural regeneration.

• Use Condensed Resin: claim double rewards and cut the number of fights.
• Watch for Ley Line Overflow: during double events, use all daily claims.
• Farm in co-op: faster clears, and lower-investment accounts can still run it reliably.

XP Book Sources That Cost No Resin

• Serenitea Pot Realm Depot: 20 Hero's Wit per week as passive income.
• Stardust exchange: buy books with Stardust, though Stardust should go to monthly Fates first.
• Battle Pass: both the free and paid tracks give books, with the paid track giving more.
• Event shops: major events often stock 100 or more. Clear these first.
• Commissions, first-clear domains, and quest rewards: small but steady.

Level 80 or Level 90?

The answer depends on the character's kit, not preference:

• Worth pushing to 90: Swirl and transformative reaction triggers such as Kazuha, Venti, Kuki Shinobu, and Raiden Shogun, and HP- or DEF-scaling characters like Zhongli, Furina, Hu Tao, and Arataki Itto.
• Fine at ascension 80: pure ATK main DPS such as Kamisato Ayaka, Ganyu, and Diluc, who gain under 5% damage from 80 to 90.
• Supports stay at 80: characters like Bennett and Xingqiu only need the final ascension to unlock their talent cap.

One more detail: stopping at 89 saves about 28 books with virtually no difference in performance.

Common Mistakes

• Pouring all resin into XP lines: neglecting talents and ascension, so damage never rises.
• Keeping only purple books: tossing the lower tiers wastes them when topping off EXP.
• Leveling everyone to 90: XP books never last.
• Pushing the wrong characters to 90: minimal return for a huge cost.
• Spending Fragile Resin on low World Level lines: half the efficiency.

Bottom Line

Character EXP comes down to one rule: 80 is the default and 90 is the exception. Level 1 to 90 takes 8,362,650 EXP and roughly 418 Hero's Wit, with 171 books in the final ten levels alone. XP books mainly come from Blossom of Revelation (about 110,000-135,000 EXP per 20 resin, best at World Level 6+), supplemented by free sources from the Serenitea Pot, Battle Pass, and events. Reserve level 90 for HP/DEF scalers and reaction triggers, and your book stock will last.
