Abyss

Abyss is an Elemental Synergy that is activated through the use of Dual Brave Burst. A bond pair with this Elemental Synergy requires two Dark units.
When a DBB with the Abyss synergy is used, Piercing Additional Damage is afflicted on the selected target, provided it is Light element. The higher the Bond Level, the stronger the effects of DoT become.
If a DBB with Abyss targets an enemy that is not Light element, Piercing Additional Damage will not apply at all.
