Applying Threads
Threads may be applied to armor using the Alteration Apparatus. Each piece of armor has a unique set of Thread Slots with their own variety of levels. Some Threads may require a Thread Slot of a minimum level, but many threads simply increase in power based on the slot they are given.
Threads only apply a single time on an entire armor set, and they do not stack. For more information on applying threads, see the Alteration Table.
