Disgaea D2 © 2013 Nippon Ichi Soft., Inc.
Gameplay in Disgaea D2 remains the same as other core Disgaea games in the series. Monster Mounting is a new feature that replaces Magichange from Disgaea 3 and Disgaea 4. A humanoid character is able to ride on top a Monster allowing the humanoid character to attack on top of the monster while the monster takes damage for the humanoid character. Characters can also build relationships with each other and their compatibility is determined by a heart scale of 1 to 5. This is called Likeability. Likeability also affects the strength of collaboration attacks used when Monster Mounting depending of the relationship established between a humanoid character and a monster character, as well as the strength and probability or Team Attacks.
Another feature is the Cheat Shop, which allows the player to modify certain attributes such as lowering the gain rate of something like experience, to raise the gain rate of something else, like Hell. Other changes that enemies and players will have substantially increased HP and SP beyond 10 billion or more, up to 99 billion, unlike the other Disgaea games. The cap can also be increased further due to the new Rasetsu which gives all enemies a new stat multiplier. The player can gain a very small percentage of the enemy's stats when he defeats enemies in the Land of Carnage mode.
Stronger Enemies bills have been changed to a Cheat Shop feature and can be changed freely. Throwing is not limited to throwing straight similar to a Gun's range, but the character can now throw freely within his range similar to the range of a Bow. The Item Bag and Warehouse have been merged into one, with different categories for each Item and the player can have up to 999 Items. The Item World has been renamed to the Item Sea, with changes to Mystery Rooms, Item Assemblies and the inclusion of Bonus Stages which replace Reverse Pirating. The Devil Dojo is a new feature that allows players to increase their Aptitudes to 300%, similar to the Class World and Chara World from previous games. It also can increase EXP, HL, Mana, Weapon EXP, and Skill EXP for characters as well. Multiple characters can be assigned to gain each effect of the Devil Dojo, similar to the Club and Evil Symbol system in previous games.
Weapon Mastery has returned from Disgaea - Hour of Darkness and Cursed Memories. A new feature is that players can raise the rank of a Character's Weapon Mastery when creating a character, or determine a mage/skull's Elemental affinity. Skill Boosting has been removed which allows for a more balanced damage formula like in Disgaea 1 and 2. Bills can be passed and Legendary skills can be bought with Hell instead of Mana. The player can change the character that they use to move around the base instead of being limited to Laharl. Land of Carnage is now unlocked after beating the game as a feature in the Cheat Shop rather than being a separate world. The X-Dimension/Dark World does not return in Disgaea D2, however. Other changes include visual improvements to Menus and HUDs, a more detailed movement grid, and a provided description for the effect of each Innocent.
