Similar to the torch bug, but with amulets.
^This was used in the torch to fix the bug, so it or something similar for TUNING should also be used on the amulets as well.
Affected amulet colours: Yellow, Blue, Purple.
Put on and then off a yellow/blue/purple amulet at any durability relatively quickly and it will never deplete. Can stack this by using two amulets for infinite amulet effect uptime.
