Memento

Mementos (called Nensou in Japan) are a mechanic that adds something similar to a fourth gear slot, although the attributes do stack with gear attributes. A memento will grant a minor attribute bonus to whomever equips it. Then, depending on the memento, it will also grant additional, larger attributes to units of a certain group (such as a country) and/or specific units. In the example to the right, all units get a minor health bonus, units from Slothenstein get a large health bonus, and Fiona, Edgar, and Veloz get an agility bonus on top of their other bonuses. Mementos can also provide special abilities or skins to the unit wearing it. For more details, see Memento.

Base Stats
The base stats provided by a memento are only given to the unit who equips it. These stats scale with the level of the memento.

Group Skills
The group skills of a memento are provided to all units within the unit group that are present in the party, as long as one unit in that group has the memento equipped. The group skills will not stack if multiple units in the group have the same memento equipped or in general if you receive the same stat bonus from multiple group mementos in the party. There may be multiple group skills on a memento with different unit triggers- often one group skill is for a single or small group of units, and another is for a much larger group of units. These stats scale with the level of the memento and also may gain additional bonuses with limit breaks.

Group skill benefits are only provided in combat, which means that if the unit dies you will lose the buff. If the unit is in subs, you will not get the benefit until they enter combat.

Vision Abilities
Vision abilities on the memento are generally available without limit breaks or level requirements, but some scale based on the limit break of the memento. Some vision abilities are available to all units, but others may be restricted based on various factors such as unit, job or origin. Some vision abilities are triggered manually, others are bonuses that apply when entering the map.

Vision Clear Reward
Vision Clear Rewards (VCR) are rewards provided for each 100% reached on a memento (the memento starts with 100% cap and gains 100% cap per limit break). This is often, but not always, a gear that is exclusively obtained through that memento. This gear is usually fairly powerful, and when obtained from a character's memento, these gears will often provide a special benefit to that unit. The vision clear reward is displayed in the upper right of the memento screen.

Skin
Some mementos provide a special character skin when the memento is equipped.

Leader Skill
When a memento is at max limit break, it may provide an alternative leader skill that can be selected instead of the standard leader skill when worn by the party leader. Any unit in the party can wear a memento within the same memento group to activate the leader skill. The memento does not have to be worn by a unit that is a member of the group to activate the leader skill. Many memento groups exist to provide leader skills- more will be added gradually. Memento leader skills can't be provided or activated by mementos equipped in the enlightenment gate 6 sub-memento slot.

Note: When using a mercenary, if your leader is using a memento leader skill, instead of gaining the mercenary's leader skill you will get no leader skill from the mercenary unless the mercenary is wearing a memento in the same memento group (doesn't have to be max limit break), in which case you will get double the benefit from the party leader's memento leader skill.

Leader Skill Strengthening
The benefit from the memento leader skills are increased based on the number of mementos of the same group that are equipped. For each additional unit in the party equipping a memento in the group (including sub party members), you gain a 2% bonus to the leader skill (multiplied against the base leader skill, not added). Using a mercenary with a memento in the group will double the entire leader skill including the bonus, but will not add an individual bonus for an extra copy of the memento.

Leader Skill Subgroups
There are some mementos who also belong to a subgroup (such as Torchlight Through a Looking Glass). These mementos can also used to activate a leader skill in the subgroup, but can only provide their leader skill to the primary group.

Sub-Mementos
When a memento is equipped in the sub-memento slot provided by maxing enlightenment gate 6, it does not provide full benefits. It will not activate or provide memento leader skills. It will also provide a reduced amount of benefit to base stats, group skills and limit reached bonuses (scaling from 10% at 0 limit breaks to 50% at 5 limit breaks rounded down). Mementos in the sub-memento slot do not receive alchemic boundary from quests.

Obtaining
Most mementos are obtained through summons, and will have their own roll. This will typically start with a 2500 gem pull. Typically memento banners only contain mementos.

Some memento are provided through other sources such as temporary or permanent events. Occasionally memento tickets will be given as a reward. One memento ticket is provided monthly through the login bonus.

Limit Breaking
Limit breaking a memento will increase the stats granted by it, the maximum level, adds 100% to the alchemic boundary cap, increases the alchemic boundary % gained from quests, and sometimes gives additional bonus stats at max limit break. A memento maximum limit break is 5. The vision abilities provided by memento will often also scale based on limit breaks and some are only available at max limit break. You can view the enhancements to group bonuses from limit breaks under "Enhancement Bonus". In addition, some mementos give an alternative leader skill at max limit break. Mementos equipped in the sub-memento slot from enlightenment gate 6 also will provide more benefit per limit break (stats, group bonuses and limit reached bonuses are scaled from 10% benefit at 0 limit breaks to 50% at 5 limit breaks).

A memento must be fed a duplicate memento or relief to limit break. Unlike with gear, you don't need to be at max level to limit break. You'll have to feed the memento five copies of itself to fully max it out. If the copy also has limit breaks, those will be copied to the memento you are feeding it to. Each copy of itself will also provide +5% alchemic boundary towards the Vision Clear Reward, plus whatever alchemic boundary the copy was at and experience towards leveling the memento based on the level of the duplicate copy. You can limit break a memento under "Enhance".

Relief
Reliefs are special wildcard items that can be used in place of a duplicate memento when limit breaking. Each relief is tied to a specific region and can only be used on mementos of that region. Reliefs can be obtained via the Vision Coin Exchange Shop, the TAC Coin Exchange (1 per month) or sometimes through rewards or other means.

Leveling
Memento cards gain experience by being "fed" other memento cards. See the Memento Experience Chart to check how much experience is required to level. Leveling mementos will increase the base and group stat bonuses.

Leveling Specific Mementos
There are special memento cards called Apple Ratties that provide a large experience bonus. These are primarily obtained through Apple Garden event quests, but can also be obtained through milestones, missions, and events such as Vision Quest. Increasing the level of a memento will increase the stats provided by it. You can level a memento under "Enhance [Bulk]".

Standard Mementos
Whenever you feed standard mementos (any except the leveling specific ones) to another memento (under "Enhance") the memento will gain experience proportional to the rarity and level of the memento. Because of this, it can be advantageous to level a memento some before merging it into another memento, as long as the experience required to get to the next level is lower than the bonus per level.

Note: You do not have to use a duplicate for this, but only duplicates will also increase alchemic boundary and limit breaks when used for enhancing.

Alchemic Boundary
Vision Clear Rewards, or VCR are rewards provided for each 100% of alchemic boundary on a memento. This is often, but not always, a gear that is exclusively obtained through that memento. This gear is usually fairly powerful, and when obtained from a character's memento, these gears will often provide a special benefit to that unit. The current alchemic boundary of a memento is displayed in the upper right of the memento screen.

There is no benefit from alchemic boundary aside from the VCR that you get when you reach 100%. For each limit break on the memento, another 100% alchemic boundary cap is added, and you can receive another copy of the VCR at each additional 100% breakpoint. Limit breaks also increase the % of alchemic boundary added from quests, for 1% increase per limit break. The memento does have a memory of how many VCRs have already been given, which is also added to the VCR limit when merging.

Note: Free memento generally have a limit of 1 VCR reward transmuted. Any VCR which gives only shards for a gear usually is limited to 1, but sometimes has a higher limit (you can view the transmute limit in game or on the wiki page for the VCR).

To gain alchemic boundary:


 * Feed a copy of a memento to itself. Each time you do this gives +5% plus any alchemic boundary already on the copy. You can do this more than five times, but there are only five limit break levels.
 * Run missions which cost AP (without using skip tickets) with the memento equipped to a unit on your team. This provides a low chance to gain +1% towards the VCR (plus 1% per limit break on the memento). Mementos in the sub-memento slot do not receive alchemic boundary.
 * Run special events such as Vision Clear Quest, which provide bonus alchemic boundary (typically 1% per run with a 3/day limit) to specific mementos. Vision Clear Quest Pro sometimes runs on the weekends and gives a bigger bonus (typically 10% per run with a 1/day limit) to all mementos. Sometimes specific EXs provide alchemic boundary to specific mementos (usually ones tied to that event). These bonuses are per limit break on the memento, so if the quest would give 1% and the memento has 3 limit breaks, it would give 4%, if the quest would give 10% and the memento has 5 limit breaks it would give 60%. Mementos in the sub-memento slot do not receive alchemic boundary.
 * Reminiscences of a Robot can be fed to a card to increase its alchemic boundary by 5%. This is a relatively rare drop from Vision Quest and can sometimes be obtained from other sources. There are also Destiny of a Robot which increase alchemic boundary by 1%.
