Leveling up Servants is essential for completing harder content. Servants gain levels by sacrificing other Servants or Experience Cards to them. This can be performed from Servant Reinforcement, the first option in the Synthesis menu.
As of Version 1.16.0, the maximum number of slots for "Sacrifice" was increased from 5 to 20.

Leveling Strategy

To level up Servants efficiently, simply use the best Experience Cards you can get, and aim to only reinforce with the matching class bonus whenever possible. If you want to level up classes other than the original seven, you may want to save the ALL-type Experience cards since only the original seven classes have their own dedicated class EXP cards.

Every time you feed EXP to servants or craft essences, there's a chance to result in a 大成功 Great Success (2x EXP acquired) or 極大成功 Super Success (3x EXP acquired) in JP server; Super Success (2x EXP acquired) or Great Success (3x EXP acquired) in US server.

Once your Servants' levels become higher, the amount of experience needed to gain a single level becomes steep. At this point, it is best to reinforce using only 4★ and 5★ EXP cards, and burn 3★ XP cards for Mana Prisms instead.

Stars Normal EXP Class Bonus
1 1,000 1,200
2 3,000 3,600
3 9,000 10,800
4 27,000 32,400
5 81,000 97,200

As far as farming EXP cards, because of the huge discrepancy in usefulness between 3★ and 4★ EXP cards, it is best to run the 40 AP daily training field quest if possible.

Growth Curves

Not all Servants gain equal stats upon leveling up. Each Servant has their own Growth Curve, which is what defines how many stats they get every time they level up. Growth curve trends are viewed over the entire leveling process, from level 1 to max level after ascending all 4 times.

Grailing follows a special curve which advances independently from the servant's own growth curve. 5 grailings from lv90 to lv100 grant roughly 1000 HP&Atk varying from each servant.

  • Linear: Gain the same amount of stats every time.
  • S: Gain few stats per level at the beginning and end, but a lot in the middle.
  • Reverse S: Gain a lot of stats per level at the beginning and end, but very few in the middle.
  • Semi S: Like S, but not as good at the middle, and not as bad at the beginning and end.
  • Semi Reverse S: Like Reverse S, but not as good at the beginning and end, and not as bad in the middle.
