Cheaper way to get Magik
Would it be cheaper to get magik if you didnt buy the final token on the first and second rotation and used the ones from the 3 that you get by beating the grandmaster challenge with the 6 star? That way you save up 50000 radiance which you can use to get 1 more tokens on the next rotation since the price increases with each time you buy it so you can essentially not have to buy the last token since they are the most expensive ones. = here are the calculations
Step 1: €20.000 ████░░░░░░░░░░░░░░░░░░░░░░░░░░
Step 2: €20.040 ████░░░░░░░░░░░░░░░░░░░░░░░░░░
Step 3: €20.320 ████░░░░░░░░░░░░░░░░░░░░░░░░░░
Step 4: €21.080 █████░░░░░░░░░░░░░░░░░░░░░░░░░
Step 5: €22.560 █████░░░░░░░░░░░░░░░░░░░░░░░░░
Step 6: €25.000 ██████░░░░░░░░░░░░░░░░░░░░░░░░
Step 7: €28.640 ███████░░░░░░░░░░░░░░░░░░░░░░░
Step 8: €33.720 █████████░░░░░░░░░░░░░░░░░░░░░
Step 9: €40.480 ███████████░░░░░░░░░░░░░░░░░░░
Step 10: €49.160 ████████████████░░░░░░░░░░░░░░
Fully buying the first rotation costs 281.000 radiance and if you have done the challenges buying till the 7th step on the 2nd rotation would cost an extra 157.640. This makes Magiks cost be 438.640 Radiance but if you buy only till the 8 step on the first rotation (191.360) + buying till the 9th step on the second rotation (231840) = 423200.
Its not really the craziest difference but you would be saving yourself 15440 radiance. Or if you are that amount short you would still get her.
Most expensive way would be 562.000 radiance
Inbetween buying full cycles would be 438.640 radiance
Cheapest way would be 423.200 radiance
