As this is a guide that mainly talks about items, if you want to know the repair function of NPC, just search DFO NPCs Function Guide to find my other guide about DFO NPC.

Magic Seals and Disassembling would be in this category, but they were discussed before. Let’s start with everyone’s most interested function, reinforcement. There is an NPC named Kiri who can help you make your item reinforced, or you will know that this is the ‘upgraded’ function.

The value of reinforcement is below.
*1) you can get defensive attributes on your armor. Or you can get piercing values to physical or magic attributes. The higher the reinforcement, the more exponential the benefits you can get. So a +14 would be exponentially stronger than a +12.

However, there are cons. There are some cons of this method. The main one being there is a chance of failure. Beyond +10, your equip can break entirely in fact. Failing before +10 would just revert your reinforcement by a few upgrades (e.g. +9 becomes + 6). You can buy DFO gold to cover the cost to ask NPC help you. And it’s a huge gold sink as each reinforcement also costs a ton of gold. Not to mention each upgrade costs clear cube frags (10 more per each reinforcement so to get to +10, you’d need 100, while +11 would cost 110).

There is a ton of luck involved as well. The chance of success lowers every upgrade you succeed so getting a +15 or +16 would cost an astronomical figure unless extremely lucky. It is suggested that you do not upgrade your weapon until at the end of the game. And another key fact is that reinforcement helps out percentage skills mainly. Suju Reinforcement helps out fixed mainly. If you don’t know these terms, refer to part 2! I think sometimes it costs some DFO gold to ask NPC help you.

Eventually, I plan to detail the specifics of Kiri/Suju, but as this is a beginner’s guide, there’s no need to just yet. Getting too detailed would be an advanced topic.

2) Besides, Crafting items is to modify items for you. Obviously, many players know players can craft some basic materials into different materials, which comes in handy for quests which need these various materials.

There are two ways for crafting. One is to go to Seria to craft it up with her, and the other is to go to Roger. One thing I should mention is that Seria is technically more expensive than Roger. Even, Seria is not really crafting materials. Just as you can sell crafted items for the basic ones. I think you can use DFO gold to buy from other players. For more crafting options, you should go to Roger.
