Dust has a singular but important use: to upgrade Trinkets into a higher level.
The amount of Dust needed to upgrade a Trinket to each particular level is listed below:
Level 1: Default
Level 2: 10 Dust
Level 3: 20 Dust
Level 4: 40 Dust
Level 5: 80 Dust
Level 6: 160 Dust
Level 7: 320 Dust
Level 8: 640 Dust
Level 9: 1280 Dust
Level 10: 2560 Dust
Total Amount Needed: 5110 Dust. For the cost of next level is 10*2^(level-1) for the total cost up-to level just subtract 10. Example is The cost to level up to say level 10 from level 9 is 2560 so the total cost for level 9 is 2560-10 which is 2550.
To get dust, you must either reclaim a Trinket or a Dust Capsule.
