Players can find the Item Lab in Central City on the right side when entering from the Red Gate. At the lab, you can upgrade your weapons and units in various ways.
You can enhance your weapons / units by feeding other weapons / units to them, and this process will cost 1,000 ~ 4,000 Meseta and 1 N-Grinder per weapon / unit fed.
Every 20 Grinds will add 1 Special Ability Slot. +20 will be 3 slots and +40 will be 4 slots.
Gold and Silver enemies can drop Gold and Silver Swords with have a special ability on them called [Esperio]. The Special Ability gives a bonus amount of EXP to a weapon when it's fed to it. Golden gives 800 EXP and Silver gives 600 EXP each.
There is a MAX Grind Level based on the rarity of your Weapon / Unit.
- Grind Limits
- ★1 – +10
- ★2 – +20
- ★3 – +30
- ★4 – +40
While there are Grind Limits, your equipment can Limit Break to increase to the next rarity's limit.
Limit Breaking your weapon will allow it to be grinded even further beyond! A Weapon can Limit Break up to +40 Max Limit. You'll need to Monotite for a +20 Max Limit, Dualonite for a +30 Max Limit, and Trinite for a +40 Max Limit.
Special Abilities are Item Capsules that can found out in the World. You can also trade the lower tier Capsules and other materials for stronger capsules in the Item Lab.
Capsules have a rate around 8% ~ 10% per capsule used. You can use up to 10 of each Capsule for a total of 80% ~ 100% chance to succeed the Special Ability. Newer Capsules later on may have lower rates.
Once a Special Ability has succeeded, you'll be able to keep it on your equipment at 100% success rate each time you go to add another Special Ability.
Potentials are special effects based on the Weapon Series. You can unlock the potential by paying Meseta and Photon Chunks along with Monotite, Dualonite, or Trinite depending on if the Potential is going to Lv1, Lv2, or Lv3.
Potentials in this game can become Level 4, but to do this you'll need 5 N-Excubes. Excubes can be obtained from leveling up past the Level Cap.
Multi-Weapon allows players to create a 2-in-1 weapon by paying Meseta and Photon Quartz. The combined weapons will let you use both weapon's attacks on the same palette allowing to swap between the two weapons without any delay.
- If one of the Weapons in the Multiweapon is not one from your Main/Sub Class: You cannot use the Photon Arts or Photon Blast, but you can use the Normal Attack and Weapon Action.
- The Photon Blast used is of the weapon you have out.
- You'll only need to upgrade and grind the primary weapon, if you plan to make a multiweapon. The secondary weapon will use the stats of the primary.
