Labyrinth of Chaos

Overview
The Labyrinth of Chaos is an optional end-game maze that consists of random areas seen throughout the game with portals leading to the next section of the maze. Every 10th floor has the White Rabbit, a chest that contains an item, as well as three additional red chests and a green chest that requires winning a tough boss fight to proceed. Every 100 floors you have the option of fighting a super-boss for a better reward. You are also unable to save, with the exception of after the rematches of each boss. You can only start from the 1st floor, and, once you have reached them, you can restart from floors 101, 201, 301, 401, and 601.

Another note is that Abilities/Accessories, such as the Demon Ward Bracelet item/Encounter Half Special Ability have no effect whatsoever while inside the Labyrinth of Chaos, as enemies are visible encounters instead of random ones. This makes prolonged explorations of each floor a dangerous gambit if one runs out of supplies to keep their HP/MP supply in balance whilst searching for items/NPCs, as regular enemies are much tougher in the Labyrinth of Chaos than their usual counterparts. Escaping from regular enemies is also made much harder, if not impossible most of the time, thus making it mandatory to fight your way through every regular encounter you face to progress forward.

Differences with the base game

 * Enemies encountered get more powerful abilities at Floor 100 and above.
 * You won't get temptation or H-Scenes.
 * Several enemies get magical or physical reflection. As a rule of thumb, enemies with a mostly mechanical body will get physical reflection while magical ones will get magic reflection.
 * As Rare Points increase, the number of chests by floor decreases while the quality of their content increase.
 * Buffs and blessings acquired activate at the beginning of each fight until the next Boss floor.
 * Enemies don't randomly appear as they do outside of the Labyrinth. Instead, enemies wander the overworld and chase you down, engaging in combat should they touch you. The speed of these enemies varies on the species, with Fairies and Harpies being much faster than the Dragon Girl or Anglerfish Girl. The enemies encountered when touched are related to the type of enemy represented in the Overworld, either by species or by area of encounter. This also means that each floor has a limited amount of enemies, making farming impossible.
 * This iteration of the Labyrinth introduces "Special Floors". These floors do not count towards the total amount of floor and will contain a singular event, which can grant rewards if done correctly.
 * A new system for determining progression has been set up, which are "Rare Points". Rare Points are gained when escaping the current floor (10 for the main labyrinth, up to 50 for trials and Carnage Labyrinth), when defeating a monster (1 for the main labyrinth, up to 10 for trials), or with special events/NPCs. The quality of the loot found in chests increases with the number of Rare Points gained, but so does the strength of the enemies and bosses found in the Labyrinth. Thus, it is possible to continue in the Labyrinth for long periods of time by avoiding every encounter, although this will result in weaker loot. Rare points are currently capped at 20,000.
 * Excess rare points become "Usagi Points", used to exchange with White Rabbit every 10 floors, but not any 100th floor. See the Rewards section below for what these points can be used for.
 * Items are radically different from the base game. They are called "secret equipment", and are affected with an additional level (+x) defined by the number of Rare points you have when acquiring equipment, and are colored in the inventory (blue = common, yellow = rare, orange = legendary). They have random stats and bonuses, save for legendaries that also include predefined bonuses.
 * The different areas available in the Labyrinth of Chaos yield certain kinds of equipment more often than others. See the section on the Trials of Chaos for more information.
 * Despite the Reaper stating that the Labyrinth of Chaos is now open after the end of Part 1, you are unable to access it until the end of Part 2.

Trials of Chaos
Trials of Chaos are an alternate entrance to the main Labyrinth of Chaos. They act as a more specialized and farmable version of the main Labyrinth, as they grant you access to several Trials that each gives you access to certain kinds of equipment. The trials are as follows:

Eternal Forest: This area gives you access to lightweight armor such as robes, luxury hats, and martial art outfits. As the name of this area would suggest, it is made out of the forest-themed maps of the world, with plant, insect, elf, fairy, and sometimes beast monsters being the most common types.

Carnage Hill: This area gives you access to heavy armor such as shields, helmets, and other types of heavy armor. As the name of this area would suggest, it is made out of the mountain-themed maps of the world, with a rather wide range of monsters.

Sea of Truth: This area gives you access to lightweight and quick weapons such as ninja swords, bows, and katanas. As the name of this area would suggest, it is made out of the water-themed maps of the world, with mermaid, sea-dweller, and scylla monsters being the most common types.

Oblivion Desert: This area gives you access to more unusual weapons such as plates, scalpels, harps, and fans. As the name of this area would suggest, it is made out of the desert-themed maps of the world, with land-dweller and insect monsters being the most common types.

Recursions Cavern: This area gives you access to weapons requiring high attack power such as heavy swords, hammers, axes, and fists. As the name of this area would suggest, it is made out of the cave-themed maps of the world, with insect, ghost, undead, land-dweller, and sometimes yoma monsters being the most common types.

Phase Tower: This area gives you access to magical weapons such as rods, sickles, and grimoires. As the name of this area would suggest, it is made out of the interior-themed maps of the world, with magical and yoma monsters being the common types.

Town of Demise: This area gives you access to accessories with a variety of effects. As the name of this area would suggest, it is made out of town-themed maps of the world, with angels being common there.

Infinite Chaos: This area gives you access to gems, which are able to be equipped on weapons and armor. As the name of the area would suggest, it is made out of the chaos-themed maps of the world, with Apoptosis and Chimera's monsters being the common types.

Each trial has 5 levels, with each of them having 10 floors to go through before fighting the boss. You start with only the first level accessible. Defeating the boss of a level will grant you access to the next level, which will automatically start with far more Rare Points than the last, with the last level starting with 7000 rare points. Each trial will also reward the team with EXP, Job EXP, gold, and affection based on the trial level.

Blacksmith
From the entire Labyrinth of Chaos, the White Rabbit has recruited the best blacksmith she could find: an adult version of Papi. She appears to be deeply knowledgeable about the nature of the weapons found there and will offer you many kinds of services.

Apply Gems: Allows you to apply Gems to your Secret Weapons or Secret Armor. Gems have special effects that will be active when you equip the weapon or armor to which the gem is attached. A Secret Tool can only have a fixed number of gems attached to it, and thus has limited sockets to insert gems in. Weapons and Shields can have up to 3 slots, Hats and Armors have 1 or 2 slots, and Accessories may or may not have a slot.

There are 6 types of Gems, which roughly all follows the different types of ability a character naturally possesses. Those types are Combat, Job, Magic, Defense, Special, and Equipment. A weapon can only have one type of gem equipped at one time.

Notably, Equipment Gems aren't available naturally like most other gems. They can instead be found by Refining either Heaven Stone(s), Sky Stone(s), or a Void Stone(s) alongside the equipment chosen to create the gem. Equipment gems created this way will grant most passive effects that the equipment had, and will provide equipment-specific stat boosts.

For instance, when an Archangel's Bra equipment gem is created, the gem will grant holy resistance 50%, lightning immunity, and boost most stats (the stats that Archangel's Bra boosted), with Defense and Willpower being boosted the most (roughly 30% boost).

Equipment gems tend to be extremely powerful than other gem types, so it's recommended to apply an equipment gem whenever possible.

Gem Stat Boosts: Gem stat boosts stack multiplicatively - for instance, two "+20% Dexterity" gems on different equipment will give a cumulative increase of 44% to the dexterity stat. Stat boosting gems on the same equipment will also stack multiplicatively (possible through equipment gems). Gem skill/type boosters stack additively - having two instances of "Holy Booster 30%" will yield a 60% boost to Holy element - if you have a "Holy Booster 200%" weapon, then the total boost will be 260%.

Rate boosters stack based on the current rate - for instance, if a character has a crit rate of 40%, then a "Crit Rate 50%" gem will only apply to the 100%-40% = 60% critical hit rate that has not been filled yet (since the crit rate maxes out at 100%). The 50% boost will apply to the 60% rate, boosting the stat by 30%, which gives a 40%+30% = 70% crit rate at the end.

In short, rates stack according to the formula: Rate = (1-b1)(1-b2)...(1-b_n), where the b's indicate boost rate (40% = 0.4).

Refine Gems: You are able to ask Papi to "refine" gems for you, at a fee. Fusing multiple of the same gem can grant you a gem with an increased effect. For example, five 10% HP gem will give you a 20% gem. Fusing a piece of equipment with a rare stone through refining will give you an "equipment gem" - this is the only way to get an equipment gem.

Enhanced Secret Equipment: You can also Enhance your Secret Equipment by synthesizing two pieces of Secret Equipment together. While item A will gets its power level increased by 1 (regardless of the power level of item B), item B will get consumed. You can only synthesize two Secret Equipment of the same type, weapons with weapons, armor, and accessories with armor and accessories. Also, the item being consumed to upgrade another cannot be of a lower level than the item being upgraded. Thus, an item with a power level of 2 cannot be upgraded with an item of power level 1. The highest naturally found equipment is +29.

Notably, while enhancement increases equipment stats, passive effects of the weapon will not be strengthened, and a weapon that was leveled up through enhancing will not be as strong as a weapon naturally found at a high level - for instance, a weapon that was found at +13, and leveled to +25 will be much weaker stat-wise than a weapon found at +25. Also, while weapons found at +13 may have "holy booster 56%", the boost amount will remain at 52% no matter what, while weapons found at +25 may have "holy booster 110%", etc. Nevertheless, enhancing equipment can help you advance further and find higher-level equipment.

Carnage Labyrinth of Chaos
Upon reaching the final checkpoint (Floor 601) a new option appears when trying to enter the labyrinth: challenge Carnage Labyrinth of Chaos.

Carnage LoC is different from the normal version in a multitude of ways:


 * The difficulty. Enemy level scale by a factor of 2 for 5 floors, making raw damage strategy fall off at higher levels.
 * Boss Floors are more common. Each floor ending in 4 or 9 will be a boss level, and a super boss floor every floor ending in 5 and 0. To top it off, fighting the super boss is mandatory, the standard boss cannot be fought.
 * Superboss treasury is upgraded from 6 green chests to 5 green and one platinum chest.
 * Rare Point accumulation is boosted. You begin with 16,020 RP, gain 20 RP per floor and killed enemy, allowing you to reach the 20 000 points cap extremely fast, allowing access to +31/+33 equipment.
 * Legendary equipment is way more common and can be found even in red chests. Additionally, green chests guarantee legendary gear, while platinum chests give an increasing number of legendary items as the player progress.
 * The addition of Carnage Bonus Points. You start with 1, and gain 1 every floor ending with 5, and 2 with one ending with 0, maxing out at 10 points at floor 30. They are used in two ways:
 * All Usagi Point gain is further multiplied by the CBP value. For example, with 10 CBP, the enemies will drop 200 UP instead of 20.
 * Platinum chests give a number of legendary gear that is the same as CBP.
 * Several characters that appear on normal floors will have their features removed or changed. Gob won't let you use her taxi service (offering you an Elixir instead), Black Alice will give you her reward without having you clear the required 10 floors first. Cupid still offers her enemy weakening service as usual, but it doesn't do anything.
 * Carnage has 3 more achievements to obtain by clearing 10, 50, and finally 100 floors. The highest Carnage floor is also recorded separately.

LoC Scaling
There are 2 values affecting the Labyrinth of Chaos: Rare Points (or RP) and Monster Levels.

The former only affects loot and has a maximum value of 20000 (Starts at a fixed value depending on the level of Labyrinth/Trial you start at). Once you reach that value, whether you're on floor 800 or 8000, the quality of loot will remain the same.

Monster Levels only affect how the stats of monsters increase and are a value that's hidden from the player. It goes up every time a player goes up one floor, one special floor, or if the player skips floors. How Monster Levels increase depends on the floor number.

Other

 * Red Chests can contain Food, Materials, Non-LoC Accessories, Either a common or rare LoC item or a Gem. They cannot contain legendary gear.
 * Blue Chests always contain a rare LoC item. They can not give Legendary gear
 * Green Chests have the same loot as blue chests, but may contain Legendary gear (10% chance when Rare Points >5000)
 * Platinum Chests always contain Legendary gear.
 * Only one non-red chest can spawn on a floor, excluding special floors.
 * After reaching the cap on rare points, the rewards from special floors become Legendary gear.
 * The stats from enchanting a LoC equipment are based on the base stats of the weapon.
 * The base stats of a LoC equipment are based on the rare points you had at the time of pickup.

Lists of the Legendary Weapons/Armors/Accessories/Enchantments are below.


 * Legendary Weapons


 * Legendary Armors


 * Legendary Accessories


 * Special Effects

Trivia
The Labyrinth of Chaos was radically different in Part 1.


 * Trials of Chaos and Special Floors didn't exist. Instead, teachers' NPCs were found randomly wandering on floors like the other ones.
 * Enemies were random encounters just like in the base game.
 * The quality of the content of the chests was defined by bearing (1-49 = low quality and joke items, 51-99 = decent items, 101-199 = later part 1 items, 201+ = early part 2 tier 3/4 items)
 * Black Alice gave out mid-part 2 items. The items she currently gives out were available as a reward for beating the *100 floors super bosses.


 * LoC seems to be inspired by the Disgaea series, being a typically post-game modifier/separate dimension that dramatically increases the difficulty of the game.
