Hello,

All depend on how you want it to work.
You can do this with a relog just by adding a few lines in a stored procedure (Doesn't need any merchant or NPC, just relog with the item in a special slot) or reversing the ps_game.exe which could directly reroll your item in game so without any relog. The second way is more difficult but also more professional.

Create 2 Quests. The first will need SHA letters to finish it and the second IYA Letters to finish it. Each quest will give you a part of a word. The Sha item and the iya item. (items created by you)

Then add a last (or maybe more than 1. Depend of what you need) quest which will be finished by giving to the NPC the 2 parts of the word. Then as reward give to player a special item like a "Ulti Rec Rune (+45for +45rec +45luc)" Or something like that.
Then use this: [Only registered and activated users can see links. Click Here To Register...]
