New Type (NT) Weapon Grinding

NT Grinding Mechanics

New Type Weapon grinding works with the concept of having an EXP Gauge.

The system does not accommodate for the extra EXP fed into the weapon, as you would need to unlock the Potential at +10 for you to move to grinding for +20 and so on.

With this, only placing or feeding weapons that has the right amount of Grind and EXP value would be optimal to avoid wasteful grinding and preparing for NT fodders.

New Type Weapons also have the concept of Overlimit. The highest grind of +30 can be increased up to +35 by feeding the NT Weapon with another copy of the weapon.

Since the March 8, 2017 Update, the Overlimit of NT Weapons was changed into an additive behavior: when grinding an NT Weapon with +30 grind cap with the same weapon with a +31 grind cap, instead of it increasing to +31, as it previously did, it will now account for the Overlimit previously applied and will give a +32 Grind Cap.

	180	90	185	100,000	5.3 / 1k	2.7 / 1k

• The EXP Given by NT fodders is the total EXP that it took to grind it to that level. Say we have a weapon at +10, the EXP that it would give as a fodder would be the EXP it took to grind it to 10, which is 50, divided by 2; along with the base EXP value, the fodder would give a total of 27 EXP.
• Old Type weapons are treated as New Type Weapons with 0 grind level, no matter that its grind is; a OT Weapon grinded to +10, with a level 3 Potential unlocked would just give the same EXP as an ungrinded NT Weapon.

Attribute Addition Mechanics

Attribute Grinding is a way to increase your Weapon Element, thus making them stronger. The system follows a simple mechanic on upgrading Attributes which are:

• Combining two copies of the weapon of the same element will give an additive effect on the element. (e.g two 20 Katana will give 40 .)

• Combining two copies of the weapon but of the different element will give the base weapon an increase of 10 in element. (e.g upgrading a 20 Katana with a 25 one will give 30 .)

• Using a different weapon but of the same type and rarity will only give 1 element increase to the base weapon.

Both Old-type and New-type weapons follow this mechanic. The only difference between the two is that you'd have to "feed" the Attribute Fodder for the New Type Weapon while there is a separate Attribute Grinding option in the Item Lab for Old-type.
