A mode bar represents the state an enemy is in during battle. Mode bars are yellow and appear under enemy HP bars. Damaging an enemy or using special skills increase or decrease an enemy's mode bar depending on the current mode.
There are three distinct modes: Normal, Overdrive, and Break. These modes affect enemy abilities and attack patterns. Bosses typically have a mode bar, but not always. Normal enemies may also have a mode bar. Mode changes occur instantly when the bar is filled/depleted through ability use or other players in a raid. During attack phases, the change only occurs on at the start of the enemies turn, potentially wasting a lot of damage when the bar is nearly full.
Different enemies can have drastically different bars, some fill and deplete fairly quickly compared to damage dealt, others very slowly, some may enter Overdrive fairly quickly and take a lot to Break, and so on.
For some boss fights with multiple enemies, the mode bar is shared between the boss and other enemies. The bar will be displayed under the boss's HP bar, but the mode will affect all enemies, and anything done to the other enemies will affect the bar accordingly.
Damaging an enemy or using skills fill the mode bar until it enters Overdrive mode.
- Enemies may use special charge attacks.
- Enemies may keep one or more charge diamonds filled after using a charge attack.
An enemy in Overdrive mode is not always disadvantageous for the player. There are some skills that are more or only effective while an enemy is in Overdrive such as the Knight skill Overdrive Surge.
- Enemies cannot fill more charge diamonds. Any charge diamonds that are already filled when entering Break mode are kept, however.
- Enemies cannot use charge attacks, even if all charge diamonds are filled. Enemies will still use triggered attacks if an HP or buff/debuff condition is met.
- All allies gain a bonus to multiattack rate.
Break mode ends after the enemy takes enough damage or after enough time has passed. Inflictingon an enemy in Break mode increases the amount of damage and/or time needed for Break to end. The exact amount of damage and time an enemy spends in Break mode varies based on the enemy. As a general rule of thumb, all enemies will stay in Break for a minimum of 10 seconds, even if it receives damage surpassing its break damage value.
There are some skills that are more or only effective while an enemy is in Break mode such as the Thief skill Crack Shot.
There are characters skills and buffs that directly affect an enemy's mode bar. Notably, the raid salute when being knocked out as a Hawkeye gives all other players in the raid , a buff that simultaneously builds a Normal mode bar more slowly while reducing an Overdrive mode bar more quickly. Arriet also grants this buff to your party. Rackam's Duration, the effect's namesake, is a simple one-shot reduction of an Overdrive mode bar.
