- For the RPG class, see Tinker.
Engineering enchantments, also known as tinkers, are unique gear enchantments that may be used alongside regular enchantments. They can be placed on the Gloves, Belt or Cloak.
Glove enchants generally provide a throughput bonus and do not have any backfire effects. Belt enchants are utility-based and can sometimes backfire for adverse effects, or simply fizzle out.
Tinkers in 
380-410 skill range are learned from trainers. 
425+ skill tinkers are learned through rare procs while crafting with engineering, similar to an Alchemist's discovery. However, if the engineer hits 525 skill without discovering them all, the remaining ones can be discovered by crafting an 
[Overpowered Chicken Splitter], which teaches one of the tinkers.
