# Level up

Level up cost varies and ties with the rarity of the headphones

LC = Level-up cost

R = Current Rarity, Dope =1, Re =2, etc

CL = Current Level

| LC(HUT) = 8+ current level \* 4 + 10\* (R -1) |
| --------------------------------------------- |
| LC(HBK\@level4) = 30 + 20 \* (R -1)           |
| LC(HBK\@level14) = 80 + 40 \* (R -1)          |
| Cooldown time (hours) = (CL + R -1) \* 3      |
