Hey guys, so originally I was going to make a post asked how many Wishing Credits you get for leveling up Refines during the rebate, but I realized I could just look up videos with people using them so just wanted to share this in case anyone else is wondering!

Level 1 > 2

+ 5 (Basic Refine)

Level 2 > 3

+ 10 (Basic Refine)

Level 3 > 4

+ 15 (Med Refine)

Level 4 > 5

+ 20 (Med Refine)

Level 5 > 6

+ 25 (Med Refine)

Level 6 > 7

+ 50 (Adv Refine)

Level 7 > 8

+ 100 (Adv Refine)

Level 8 > 9

+ 200 (Adv Refine)

Total: + 15 Basic, 60Med, 350 Adv Refines

Total Refines needed to max level 10 (Worst Case):
45 Basic + 140 Med + 1350 Adv
