Start producing as many of the item as you can. You will need to make a LOT of the item so expect your workskills to go into over-drive.
Save anything with refinement greater than 1. If you have tons of cash, refine the zeros into level 1s.
Keep an eye out for anything that has four things in the slots. I've never seen anything more than four. It will usually be a level 0 item.
There are some rare stats so make sure they are all on The Refinable Stats List
Once you find it, it becomes your "candidate".
Save and refine upwards (ideally) until you have four level4, four level3, and so on down the line.
Sell off your rejects. You will earn lots of money, but you will need it for refinements
Ideally you should wait until you done the step above before you try and refine your "candidate" as a better candidate might present itself.
Rename the Pet. This is what your weapon will be called.
If you have a throwaway / low level pet, you should morph before you enhance/reinforce, as it will blow stats as you upgrade the weapon/armor. You will get stats that the low level pet couldn't reproduce, but high level merges are bound for disapointment.
If you want to control the element, the morph must be the LAST thing done. Follow other morphing rules.
When you refine or reinforce weapons the element WILL change. (haven't worked out which is which) If you have a throwaway / low level pet, you should morph before you enhance/reinforce, as it will blow stats as you upgrade the weapon/armor. If you want to control the element, the morph must be the LAST thing done. Follow other morphing rules.
Once you've filled up the pyramid and decided when to merge the pet, make enough to refine your candidate into a level 1 refinement. If you have a weak pet you are merging, merge it now.
Refine up the chain until you've reached your level five.
If you wish to use reinforcement,(cash shop item) I wouldn't go beyond level three because even level 3 is hard to get. Your choice of course.
If you have a strong pet you are merging, merge it now.
