Chara World (Disgaea 5)

The Chara World is a feature in Disgaea 5: Alliance of Vengeance that allows characters to become stronger.

It is opened at the beginning of Episode 6. Entry cost starts at 100 Mana, and each successful visit multiplies the cost by 10, capping at 100,000 Mana. Unlike previous games there's no limit to the amount of visits, with Reincarnation simply resetting the Mana cost back to 100.

It has undergone a major revamp from its previous incarnation, turning the entire feature into a board game rather than just being nearly identical to Item World, while most of its rewards remained the same. Each turn the character will roll a dice to move, with the objective of reaching the Goal that sends them to the rewards room. The panels of the board grant random bonuses or penalties, and various enemies will appear randomly through the board to impede the character's progress.

Difficulty
Only Demon is available by default, with other difficulties being unlocked by a quest that requires beating the previous difficulty. Super Overlord can only be unlocked once Carnage Dimension is available.

Panels
Most panels on the board have a special effect(positive or negative) that activates if the player lands on it. Once an effect is played out the panel becomes blank and will play no effect if landed on again.

Items
Each turn the player may use one item before they move, granting various bonuses.

Rewards
Reaching the Goal at the end of the board teleports the player to the Rewards Room, where they may select one upgrade from any of the NPCs there. There's also the option to leave without taking a reward.

Shadow Characters
From Demon Lord Difficulty onwards, a dark-colored variant of the character inside the Chara World will spawn as an enemy. Their stats are usually higher than the chosen character's and unlike normal enemies they can move through the board, but fighting them is important for character growth, as each one defeated increases all Aptitudes by 1%.

Miss Evil
Only on Super Overlord difficulty, a powerful enemy known as Miss Evil can be randomly encountered. Miss Evil is stronger than the normal Chara World residents, though she does not scale to the player character's stats like their Shadows do. She can move a long distance, nullifying the effects of every panel she passes through, but disappears after a few turns. Defeating Miss Evil rewards a Common Evility Slot(max 3 times per character), as well as a Dowsing Rod item. After she's been defeated once, a Bill can be passed that ensures she appears on the next Chara World visit.
