Rarity

Rarity is a measure of how common a specific item in the Disgaea universe is compared to others of its exact kind.

How it works
Disgaea: Hour of Darkness introduced the general rules of the system, with all subsequent games making additions or changes to it.

Disgaea: Hour of Darkness
All items have a randomly assigned Rarity value from 0 to 255. Depending on this value the item will be assigned a category, with each category having different bonuses:


 * From 0 to 7 the item is Legendary. These come with a 50% increase to their stats, up to 13 Specialist slots, and 100 Item World floors.
 * From 8 to 31 the item is Rare. These come with a 25% increase to their stats, up to 10 Specialist slots, and 60 Item World floors.
 * From 32 to 255 the item is Common. These come with no stat increase, up to 7 Specialist slots, and 30 Item World Floors.

The amount of Specialist slots increases by 1 when killing an Item King or Item God, making it 1 possible increase for Common items, 2 for Rare and 3 for Legendary.

Note that items of less common categories are harder to Steal, and Rarity 0 items are even harder to steal than the other Legendary values.

Same Rarity Bonus
If a character equips multiple items with the same Rarity value, those items get a 10% stat bonus per repetition: 10% bonus for 2 matching items, 20% bonus for 3 items, and 30% bonus when all 4 items match.

Disgaea 2: Cursed Memories
From this game onwards the amount of starting Specialist slots is lower, and now it's fixed rather than a variable amount: Common items have 4 slots, Rare items have 5, and Legendary items have 6. They can be increased exactly 2 times, either by killing Item Kings or in the Item Assembly.

A Specialist called the Collector can now be obtained, which increases the Rarity value of the item it's in.

In Common items you'll always find an Innocent Town in the 10th floor of the Item World, whereas in Rare and Legendary items the chance is more randomized.

Disgaea 3: Absence of Justice
This game introduces Magichange weapons, which normally have a Rarity of 0.

When duplicating enemy Magichange weapons with the Puppy Paw Stick however, the duplicated Magichange weapon will have the rarity of the weapon that the monster had equipped before it Magichanged.

Disgaea D2: A Brighter Darkness
This game removes Rarity values, but the categories still exist. The category of an item can be upgraded now, and this is done by going through all of its available Item World floors.

Same Rarity Bonus still exists and it only requires items to have the same category, making it much easier to activate. However, it does not apply to Common items.

Disgaea 5: Alliance of Vengeance
Rarity values return, though they have been reworked. Values go from 1 to 100 now, so the categories are assigned differently: Common from 1 to 24, Rare from 25 to 49, Legendary from 50 to 99, and the new Epic category at 100. The % stat increase is now equal to the Rarity value, rather than being a fixed amount dependant on the category.

The Rarity value of items can be increased by beating bosses, invaders, and bonus floors in the Item World, also improving its category accordingly.

Same Rarity Bonus is activated simply by items having the same category(does not apply to Common items), but the bonus per repetition has been reduced from 10% universally to 2% for Rare items, 4% for Legendary and 5% for Epic. Also, the increase from it is now added to Aptitudes, rather than being its own multiplier.

Magichange Weapons keep the Rarity value of the human weapon they replaced.

Disgaea 6: Defiance of Destiny
Disgaea 6 keeps the Rarity values and categories from Disgaea 5.
