Burst Aid is a tier 5 augment skill in FL4K's Master skill tree. While this skill is equipped, the rift created by Gamma Burst will remain for the full duration of the skill. FL4K and their allies will also rapidly regenerate health while they are near the rift.

This skill requires Gamma Burst to be equipped.


  • Health Regeneration: +20% of Max Health per second


  • The area-of-effect of the skill functions as a circle on a horizontal plane. Any difference in elevation between the character and the rift will not convey the effects of the skill. As such, it is recommended that the rift is placed on a horizontal plane the character is expecting to fight near.
