Brave Burst Skills

Brave Burst

Sapphire Noble Stein with BB ready

Every unit (barring most Enhance and Evolution units like Mimic, Metal God, etc.) is capable of performing a special attack during combat called a Brave Burst (BB). These special attacks or skills are usually stronger than normal attacks, have the potential to do more damage, attack all enemies at once, or randomly target multiple enemies, inflict various Status Ailments, heal the party or buff the party in various ways, if any.

Below each unit's health bar is another bar that fills up during combat called the Brave Burst Gauge (BB Gauge). The BB Gauge fills up by collecting Battle Crystals (BC), that drop from enemies as they are struck, or left in chests. The BB Gauge also fills up from special Leader Skill, various buffs, or item effects (such as Fujin Potion).

Once this bar is filled up, The unit's individual panel will crackle with blue lightning to indicate that the Brave Burst is ready to use. The player taps and holds down on the unit panel of the unit that will activate its Brave Burst, and swipes up to activate it. Multiple Brave Bursts can be activated in the same round, for a spectacular scene and particularly devastating attack. Like normal attacks, players should become familiar with each unit's Brave Burst animation in order to cause Spark combos.

Once activated, the BB Gauge will be completely emptied and require refilling before the Brave Burst is available again.

Super Brave Burst

Algor Halcyon Selena with SBB ready

The Super Brave Burst (also denoted as SBB) is generally a more powerful version of the Brave Burst, which sometimes will have additional effects. For example, some single-target Brave Bursts might target all enemies with its SBB version, while additionally buffing the party or inflicting Status Ailments when the original Brave Burst did not. In some cases, a Brave Burst that targeted all enemies will only target a single enemy with its SBB, but do massive damage.

Super Brave Bursts require two charges of the BB gauge in order to be usable. Where the BB gauge will flash with blue lightning to indicate that the normal Brave Burst is usable, the blue "BRAVE BURST" text will be replaced by gold "SUPER BRAVE BURST", and a gold bar will slowly fill up. During this time, the normal Brave Burst can still be used. When this gold bar is full, the Super Brave Burst is ready and the blue lightning animation is replaced by yellow flashing lightning. When a player taps and holds down on the unit's panel, two options will be presented: swipe up to use the normal Brave Burst, or swipe right to activate the Super Brave Burst.

After activating the Super Brave Burst, the BB gauge will reset completely and need to be refilled before both normal Brave Burst or Super Brave Burst are available again. Note that using the normal Brave Burst while the Super Brave Burst is ready will completely reset the BB gauge as well.

Acquiring Super Brave Burst

Only 6-star units and up and Nice Burny are capable of acquiring a Super Brave Burst. The normal Brave Burst must first be levelled to 10 (MAX), after which the Super Brave Burst will become available, at Level 1. Levelling the Super Brave Burst uses the same method as leveling the normal Brave Burst, through Unit Fusion.

However, because some Super Brave Bursts will add effects or even damage in some cases, the types of units that have the possibility to increase SBB levels may change. Where Support units may have leveled the normal Brave Burst, the Super Brave Burst may only be leveled by Offensive units for some units.

Units in the same evolution chain still have the highest chance at increasing SBB levels, regardless of types, and Burst Frogs (or Burst Emperors/Burst Queens) still have a 100% chance to increase SBB levels.

Ultimate Brave Burst

Zero with UBB ready

The Ultimate Brave Burst (also denoted as UBB) is an even more powerful version of the SBB, having the same effects as the original, but with the bonus effects changed. For example, Flame Legend Vargas has a 14 combo fire attack with an attack buff as a bonus effect, while the UBB has a bonus effect of inflicting attack down onto enemies. This means UBB can be stacked with other same buffs as BB/SBB.

Ultimate Brave Burst requires one charge of the BB Gauge to activate, but unlike the BB or SBB, the UBB requires another gauge to be filled up, which is the Overdrive gauge. Attacking the enemy will fill the gauge. Additionally, the Overdrive gauge fills after each turn and certain Brave Burst skills refill it partially.

Overdrive Gauge

The Overdrive Gauge (OD Gauge) is a requirement to fill in order to activate Overdrive Mode. When in Overdrive Mode, the UBB gauge will be available and the unit in Overdrive Mode will receive a 100% boost to Atk, Def, and Rec. The unit has up to four turns (including the turn the unit activates Overdrive Mode) to use UBB, or the unit will revert back to its regular state (with empty BB gauge), and the Overdrive Gauge will need to be refilled again.

The Overdrive Gauge also has an internal limit starting at 10000 (when the quest starts) that increases by 5000 each time UBB is activated. The maximum internal limit that the Overdrive Gauge can reach is 40000.

OD points fill up the Overdrive Gauge depending on which actions are taken. The OD point yield is listed below:

  • Normal Attack yields 300 OD points.
  • BB yields 100 OD points.
  • SBB yields 200 OD points.
  • Attacking a unit that is of the weaker element yields 100 OD points.
  • End of turn yields 500 OD points.
  • "Fills OD gauge" effects yield their proportional amount.

Acquiring Ultimate Brave Burst

Only 7-star units and up are capable of acquiring Ultimate Brave Burst. The normal Brave Burst must first be leveled to 10 (MAX), followed by Super Brave Burst leveled to 10 (MAX), after which the Ultimate Brave Burst will unlock. Ultimate Brave Burst only has one level.

Brave Burst Levels

Brave Burst abilities have levels that can go up to 10. Higher levels add to the potency of the Brave Burst, whether it is damage, potential to inflict a status ailment on the enemy, heal or buff the party. Some Brave Bursts will benefit from reduced amount of BC needed to fill BB gauge with higher BB levels.

Brave Burst levels can only be increased through Fusion. However, there is a special price discount when fusing MAX level units, to aid with the BB levelling process. More details are provided in the Unit Fusion section.

Upon evolving, the unit's BB Level will be halved, rounded down. (e.g. A unit with Level 10 SBB will be reduced to Level 1 SBB when evolving)

Levelling up Brave Burst methods:

Method BB Level received
Fusing non-evolution/fusion material Units Chance to raise by 1. Difficulty increases as level goes higher. Upon acquiring SBB at Level 1, the difficulty resets.
Fusing duplicate of the Unit
(Any evolutionary form works)
Very high chance to raise by 1. Fixed rate.

Bonded Brave Burst / Bonded Super Brave Burst

Spirit Conjurer Astrid in Overdrive, able to use Bonded BB/SBB

Bonded Brave Burst (abbreviated as BBB) is a type of Brave Burst that can be executed while a Bonded Unit is in Overdrive. Bonded Brave Bursts can be executed freely without having to fill up a gauge for it as long as the Bonded Unit is in Overdrive. Additionally, the squad only requires at least one of the units in the Bonded Pair to be in the squad to execute Bonded Brave Burst.

A Bonded Unit's Bonded Brave Burst is the Brave Burst of the unit's partner in the Bonded Pair. Extra Skills, SP Enhancements, and other buff and passive effects of the partner are not counted towards the Bonded Brave Burst.

To activate Bonded Brave Burst, the player swipes left on a Bonded Unit that is in Overdrive.

Examples of Bonded Brave Burst:

  • While Xenon, Son of Elysia is in Overdrive, he can use Estia, Regalia of Elysia's Brave Burst (Baldr's Blaze) using Xenon's own element and parameters, dealing Dark damage instead of Light.
  • While Estia, Regalia of Elysia is in Overdrive, she can use Xenon, Son of Elysia's Brave Burst (Spirit Sunder) using Estia's own element and parameters, dealing Light damage instead of Dark. Even if Xenon took the "Adds enormous BB Atk boost for 3 turns effect to BB/SBB" SP Enhancement, Estia cannot boost BB Atk of all allies using Bonded Brave Burst.

Bonded Super Brave Burst (abbreviated as BSBB) can also be used in addition to Bonded Brave Burst, which is also the Super Brave Burst of the unit's partner in the Bonded Pair. The Bonded Pair must reach Bond Level 4 to unlock Bonded Super Brave Burst. The same rules to Bonded Brave Burst apply to Bonded Super Brave Burst, allowing BSBB to be freely used while the Bonded Unit is in Overdrive. To execute BSBB, the player swipes right on the Bonded Unit that is in Overdrive.

Bonded Brave Burst and Bonded Super Brave Burst are in the same category of buffs as Brave Burst and Super Brave Burst. As such, buffs of the same type from these sources do not stack with each other.

Bonded Brave Burst and Bonded Super Brave Burst cannot be affected by the negative effects of Curse and Amnesia.

Curse Status Ailment

Lux Halcyon Atro inflicted with Curse

The Curse status ailment will prevent a unit from filling its BB Gauge, as well as preventing a unit from activating its BB (or SBB/UBB) even if its BB Gauge was full. This ailment can be remedied with the consumables Holy Water or with any BB/SBB/UBB that removes status ailments.

Leader Skill

Most units have a Leader Skill. Each unit has a unique Leader Skill to enhance the skills of every unit. However, there are certain times that the enemy has Leader Skill Invalidation which will cause unit(s) to not have Leader Skill effect for a certain of time, or throughout the battle (till the unit is Dead).

Extra Skill

Only 7-star units and up are capable of having their own assigned Extra Skill. Extra Skill will be unlocked after the unit has unlocked Ultimate Brave Burst. All Extra Skills only apply to the Unit that has the acquired skill, unless a skill has it added to BB/SBB.

Extra Skill from Elgif

Main article: Gameplay:Elgif and Emgif

Additionally, there are Elgifs that will activate a new Extra Skill when fused into a unit. Fusing an Elgif to a unit which has already received an Extra Skill from an Elgif will replace the additional Extra Skill. Using an Emgif allows the player to preserve an Elgif that has already been fused by removing it from the unit and sending it to the gift box. Emgif does not remove the original Extra Skill of the unit.


Like a unit's own level, BB levels are increased through Unit Fusion. Unlike unit levels, there is no experience gauge to fill to reach the next level. Instead, BB leveling is a matter of luck, and it appears that the higher the BB level, the smaller the chance to increase it. Each unit fused has the potential to increase the BB/SBB level, so fusing multiple units at once may increase the BB level by multiple levels.

Another caveat to leveling a unit's BB is that specific types of units are needed for the fusing. Typically, units with Brave Bursts of a matching "type" are candidates for leveling Brave Bursts. The three types of Brave Bursts are:

  • Offense – Any BB that deals damage, whether it's single target or multiple targets, including "all"
  • Heal – Any BB that recovers HP, either at once or over multiple rounds
  • Support – Any BB that boosts allies' stats, e.g., ATK, DEF, Crit

However, this is only a guideline and not the rule. Units being used as ingredients for fusion that have the potential to level BB/SBB will display a pulsating, green BBUP!? on the ingredient selection screen. A pulsating, red BBUP!! denotes a guaranteed BB/SBB level up, but is currently only available with Burst Frogs, Burst Emperors and Burst Queens.

Fusing a unit with the same identical unit(s), or its various forms of evolution, have a much higher chance of successfully increasing the BB level. For example, fusing a Dancer May and High Dancer May into a Dancer May has a really good chance at increasing Dancer May's Brave Burst by 2 levels.

GREAT SUCCESS and SUPER SUCCESS results will also affect the chances for successfully leveling BB/SBB.

Since the chance to increase BB/SBB level is checked individually for each unit being fused, fusing units one-by-one is no different from fusing multiple units at once. It is better to fuse multiple units at once because a GREAT SUCCESS or SUPER SUCCESS bonus applies to each unit in the batch if it triggers, thus increasing the chance for BB/SBB level up even more than if only one unit was being fused.

Unit Fusing Costs

Fusing costs follow that described in Unit Fusing, including how costs are discounted at MAX level, most likely to aid the players with leveling BB/SBB. When a player is focusing on leveling BB/SBB, it is most ideal to attempt this at the low levels, or when the unit has reached MAX level, when costs decrease considerably. This is most apparent with 4-star and higher rarity units, where a MAX level unit will prove considerably more useful to the player rather than a low-level unit.

Referring to MAX Level Fusing Costs, the level at which the base fusing cost exceeds that of MAX level are as follows per rarity:

  • 3-star @ Level 10
  • 4-star @ Level 15
  • 5-star @ Level 20
  • 6-star @ Level 25

What this means is that the cost per fused unit is more expensive when the unit leveling is above its listed level when compared to fusing it at MAX level, i.e., it's more expensive to try and level a 6-star unit's Brave Burst when the unit is level 25 or higher than when it is at MAX level.

Enhancements are only available to Omni Evolution Rarity units.

  • Enhancements are only unlocked when the unit has Ultimate Brave Burst unlocked and has reached the maximum level (Level 150).
  • Each unit receives 10 SP automatically on start. SP reaches 100 at maximum and can be only spent up to that amount. Additional SP can be obtained after Omni+ Boost up to 120 SP at Omni+3. An Omni+3 unit can obtain up to 130 SP when fused with Omni Emperors.
  • Spent SP can be refunded for 1 Gem.
