About This File
This is not mine this is sir @Euphy's script, i just tried using it and tried fixing it, im noob at scripting and anything else, but tried and fixed the script to my liking, you can add single npc for single +1 upgrade. i dont know how to say this maybe just look at screenshot :3 i just posted this because i think many ppl wants ticket refining like this or i dont know..
item + ticket = item
+4 +5 +5
does not let you refine if ur item is lower than the desirable refine..and does not let you refine if ur item and ticket is the same.
