Item Grinding

When you grind items you increase the strength of the weapons. Select the item you wish to grind and pay the meseta and grinder cost that's required. As you grind, your weapon will have a +number after their name. A grind value of 6 would make your VitaRod +6. If you fail a grind, the + value drops and you'll have to pay again to grind it back up.


  • グラインダー数 Grinder Cost
  • メセタ Meseta

On the grinding screen, it will tell you the success rate which is color coded:

成功確率: Success Rate (color)

  • 確実: Assured
  • 安全: Safe
  • 注意: Caution
  • 危険: Danger

And your biggest risk: 最大リスク tells you how many grind values you will drop when you fail a grind.  In your first grind you won't have any risk so you won't drop below zero.

Grind Cost

*These values may be different depending on rarity.

  • Up to +6 : 1 grinder.
  • +7 and up: 2 Grinders

Biggest Risk (Grind Failure for Weapons)

*These values may be different depending on rarity.

  • +1 ~ 3: Grind Value will not drop
  • +3 ~  6: Grind Value may drop by -1
  • +6 ~ 9: Grind Value may drop by -2
  • +9 ~ 10 Grind Value may drop by -3

Biggest Risk (Grind Failure for Units)

*These values may be different depending on rarity.

  • +1 ~ 5: Grind Value will not drop
  • +6 ~ 8: Grind Value may drop by -1

Attribute Grinding

Grinding attributes requires using the same weapon name, it doesn't matter what + values or element it has, as long as it is the same weapon. But in order to grind an attribute, the weapon should have an attribute anyway.


From the screenshot, the red box shows your 対象アイテム target item. This item will gain attributes when finished. The green box shows items of the same name that you can add to the grind. The purple box shows the 素材アイテム material items. Whatever items you selected in the green box will become the material items used for attribute grinding.

Possible Material Items

  • Weapons of the same name
  • Weapons of No Attribute
  • Weapons with different attribute from the target item.
  • Weapons with same attribute of the target item.

Each weapon you use will add a certain amount to the attribute value, those discovered so far are:

  • +1: No Attribute
  • +1: Different Attribute
  • +2: Different Attribute over 30
  • +2: Same Attribute

The highest attribute value you can grind to is 50% in alpha test 2.

Special Abilities

Special abilities lets you customize your items by adding various bonuses and parameters to them. Basically you will transfer an ability from one item to another.

The red box in the screenshot above is the target item 対象アイテム, the green box shows the list of possible items you can choose for 素材アイテム material items. The orange box shows you what ability the item has already.

This target item has 2 abilities, in our tests, items with 2 abilities needed another item with 2 or more abilities. Items with zero abilities used items with 1 or  more abilities.

Target Ability Number

  • 0 Abilities needs items with 1 or more abilities.
  • 1 Ability needs items with 1 or more abilities.
  • 2 Abilities needs items with 2 or more abilities.

Ability Description

  • The ability description box will tell you what ability is already on the weapon. It is on the third page of the item window. Some abilities will change your stats. This is displayed in the パラメーター補正 Parameter adjustment area.
  • For example Power パワー will increase striking stat by 10. Shoot シュート increase Range Stat +10, React リアクト: increases your shooting defense +10, Stun スタン increases the Stun Level, ロックベア・ソール: Rockbear Soul increases your striking by 25, HP +50, and ability stat decreases by 5.

Merging Abilities

  • If your target weapon and material weapon have the same ability, it will allow you to upgrade that ability's level.
  • For example: Power 1 パワーI (target) + Power 1 パワーI (material) = Power 2パワーII which adds 20 striking.
  • However Power 2 has an even less of a chance of transferring over.

Transfer Success Rate

  • When you transfer abilities they will each have a success rate percentage. In addition you also get an extra slot. For example, a weapon that already has 1 ability, will get 1 extra slot, which will create a weapon with 2 abilities. A weapon with 2 abilities will get an extra slot to make 3 abilities, and so on…
  • As you add abilities onto a weapon, the success rate will drop.

In the screenshot above, the target weapon has 2 abilities already, and the material weapon also has 2 abilities. Each weapon has Shoot I already attached, thus Shoot II is now selectable from the list. Though it is 80% now, it will drop as I add more abilities onto the weapon.
