Labyrinth of Chaos/Special

Common Effects
Common effects spawn on any equipment found in the LoC in a random amount. They often increase one or the other skill type, resistance or element for a given value. Said value is higher depending on the equipment level when found, and is slightly randomized as well, making it possible for an item with a higher level to have smaller bonuses than a lower level one. Contrary to base stats, these bonuses are not improved when forged.

Legendary items spawn with a fixed list of effects which value are fixed, and then a few more random common effects that are generated this way as well.

Rare Effects
Rare effects appear in yellow on items and, contrary to common ones, their values and effects are fixed. They only spawn on legendary gears, and follow the same pattern.


 * Skill Haste: One Skill Type/SP Cost +50% (if skill type use SP)
 * Skill Haste: One Skill Type/MP Cost +50% (if skill type use MP)
 * Skill Haste: One Skill Type/SP&MP Cost +50% (if skill type use both)
 * Double Action
 * Triple Action Crisis
 * +200% Damage for one Chaos Element
 * Preemptive stat up (one for each stat)
 * 50% Resist for one Chaos Element
 * Race Slayer
 * +30% Damage to Boss
 * Nullify all Status
 * -50% Damage from one Race (-30% for Apoptosis/Bosses)
 * Ability Use: Heavy Attack/Magic/Agility/Dexterity (gives relevant ability)
 * Critical Damage +200%
 * Skill Use:Hadron☆Meteor: (Pleasure/Wind/Hadron 2000% ^ of Mag, Agi, Dex), Target: All Foes
 * Skill Use:Taboo Star Talisman: (Earth/Terra 2400% ^ of Mag, Dex) | Target:Foe

The Collaboration Scenario saw the addition of rare effects that are specific to characters: they can only spawn on equipment belonging to one character, and often further enhance one of their signature moves.

Seals
Seals are very powerful effect that can appear on legendary equipment found in the Labyrinth of Chaos. A single seal will increase all stats by 110%. They also work as set, and stacking the same seal several time gives increased bonuses. They appear in green on items, and while they are rare, several seals can spawn on the same piece.

Gems
Gems are a new category of items that can only be found in the chests located in the Labyrinth of Chaos. They can be grinded in the "Infinite Chaos" trial, or at high level with the White Rabbit gacha at 200 points for 10 gems.

They can only be managed by talking to the blacksmith, who offers the following options.

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 so many 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 follow the different types of ability characters can acquire through jobs and races. Those types are Combat, Job, Magic, Defense, Special, and Equipment. A piece of equipment 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 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. The stones themselves can either be found in the chests within the Labyrinth of Chaos or bought with UP from the White Rabbit.

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 prominent (roughly 30% boost).

Equipment gems tend to be extremely more powerful than other gem types, and 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 five 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.
