Yoshitsune
- Weapon Enhancement
The "Weapon Enhancement" option allows you to enhance your weapons to increase their min-max damage.
All you need is to "feed" the weapon your enhancing with "food items" (weapons you don't want or need) and it will gradually increase in "Enhancement Level". But only until its "Enhancement Level Cap", at Level 10. Upon reaching this cap, you can no longer enhance it anymore until you've "unlocked" it for further enhancement using the "Over Refining" option.
As far as I know, enhancing your weapon has no risk at all. All you need is just an abundance of "food items" to feed it with. It doesn't seem to care about what sort of weapon types your using as a food item, nor its current durability. What is important is only that their relative "level requirements" be within 20 levels.
In other words, if the weapon your enhancing has a Level 30 requirement to use, you may only use weapons with level requirements of above 10 (that is level 11 and above) as food items. Anything below that will not help to increase the weapon's enhancement level (but will still be consumed nonetheless).
(Using Rare and Very Rare weapons as food items will often help to increase the enhancement level faster. However, unidentified weapons on the other hand appears to be treated as a less than level 10 food item. So it might be better to identify it first.)
- Over Refining
Once you've hit an "Enhancement Level Cap", you will need to use this "Over Refining" option to unlock the weapon for further enhancements.
As a "Catalyst" for this process, you will need a weapon bearing the same name as the one your trying to over refine.
If successful, the catalyst will be consumed and your weapon will be unlocked for further enhancing (until its next cap, at level 20). If unsuccessful, both the catalyst and your weapon will be gone so please note that its a pretty risky affair that your attempting here in my opinion. However, where there are risks involved, there will also be rewards.
Apparently, at each successful unlock, the weapon will gain additional bonus effects. But in order to be able to perform the unlock, you will need Yoshitsune's ability, "Polish" (研磨)*, to be at a certain level.

* The level of this ability also affects your chances of success in over refining.
** Likewise, the higher the unlock your attempting, the lower your chances of success.
*** The "Normal Combo Attack Power" most likely refers to your damage when chaining regular non-weapon skill related strikes.
**** CT refers to Cooldown Times. It most likely reduces your cooldown time to recast a weapon skill.
("Support Items" that can be used here include items that prevents your weapon from being destroyed and stuff that increases your chances of success. But these can only be bought from the Item Mall...which requires real life cash.)

- Weapon Repairing
Failed Normal Excellent Max Durability Reduced - Max Durability Increased
As far as I know, increasing Yoshitsune's "Repair" (修繕) ability would reduce the chances of you getting "Failed" repairs.
However, if your looking for a fail-safe alternative, then you would need to use some item mall "Repair Protection Man" thingy to guard your weapon during repairs. (Just tick the "Repair Protection" box beside the weapon you wish to protect.)
