It depends on the rarity of the character. Goes as follows, from reaching bond levels 6 to 9:
  • 5-star: 3 SQ
  • 4-star: 2 SQ
  • 3-star: 1 SQ
  • 2-star: 1 Golden Apple
  • 1-star: 1 Golden Apple

However, the lower the rarity of the character, the faster his/her Bond Level will increase.
Certain characters are more difficult to raise their Bond Level compared to other Servants of the same rarity, Gilgamesh being a prime example (probably due to his personality), but even in those cases, the rewards do not change.
