Users can spend MNB to upgrade the durability of their GPUs resulting in the frequency of repairs being reduced along with the associated repair costs.
Repair frequencies are calculated using a 1-year period & each increase in durability level reduces the frequency in which a GPU needs to be repaired by 3 months.
For example: a base level GPU with no upgrade to durability will need to be repaired every 14 days, a GPU with level 1 durability would need to be repaired every month, a GPU with a level 2 durability would need to be repaired every 3 months, a GPU with level 3 durability would need to be repaired every 6 months, and finally, a GPU with level 4 durability would need to be repaired every 12 months.
The chance of rolling each multiplier level is as follows: Level 1 50%, Level 2 30%, Level 3 15%, Level 4 5%. Durability upgrades can be applied either temporarily or permanently, and the chance of rolling a permanent duration is 1%.
