Limit Burst

Limit Bursts, shortened to LB, are special abilities in Final Fantasy Brave Exvius. Its mechanics are similar to the Limit Break system found in other installments of the series. Performing a certain amount of Limit Bursts earns the Limit Breaker trophy.

Overview
Each player character, or "unit", features a unique Limit Burst ability and may fall into one of four broad categories: support (those which heal the party or increase the party's stats), debuff (those which apply some ailment to the enemy), damage (those which allow the unit to perform a powerful attack), and uniques (those which do not belong to the aforementioned types.)

During battle, each unit has a Limit gauge that fills up by absorbing Limit Burst crystals. These crystals are dropped by all enemies when damaged by a normal attack. If the gauge is full, the player can use the Limit Burst by flicking the unit's window to the Ability list, and set it as the action to be taken by the unit.

Each unit has a Limit Burst level that must be maxed out to raise the Limit Burst's values, improving their effects. The maximum level 25, achievable by 6★ units. LB levels are gaine through usage: Eveytime the unit performs its Limit Burst, its experience bar goes up by one point.

In addition to usage, LB levels can be gained by fusing the base unit with special utility units – the Mini Burst Pot, Burst Pot and King Burst Pots, which add 100, 3000 and 10000 LB points to the base unit when used. Fusing a base unit with a duplicate does not give it any Burst points and levels does not carry over. LB levels do carry over, however, when a character awakens, but at the same time, the usage requirement for each LB level rises according to characters' rarity. Due to this, it is preferrable to train the unit's LB level to its highest it can for that rarity rank before Awakening the character.

Trivia

 * The naming convention of a Limit Burst having a different name depending on the unit's Rarity level is present on the first releases, but it was discontinued.
