  • Sonic Fracture's armor reduction is affected by Ability Strength.
    • To completely remove a target's armor in a single cast, Ability Strength should be increased to 143% at minimum.
  • Duration of armor reduction is affected by Ability Duration.
    • Subsequent casts of Sonic Boom reset the duration of the armor reduction and will stack the armor reduction.
  • Overlapping successive casts will stack its armor reduction effect multiplicatively.
  • Affected enemies have a green aura around them identical to that displayed by DmgCorrosiveSmall64.png Corrosive.


  • Some enemies, such as Councilor Vay Hek, have no weaknesses under their armor and therefore take more damage when still slightly armored, making it more advantageous to get just under 143% Ability Strength. A rank 4 Power Drift and a maxed Intensify can get one to 142.5%, and despite being listed in the armory as 143% will leave a small fraction of armor.
