The Defiance Break sums up to 350 based due to the listed 1 second knockdown while the actual knockdown duration is 3 seconds and thus the skill deals 550 defiance bar damage in total.
  • Despite the tooltip, the knockdown lasts 3s and therefore causes 300 Defiance bar damage. This is probably due to PvE balance for a CC-Elite to be strong in breaking defiance bars. It has no impact against other players in PvP or WvW, since the float interrupts the knockdown anyway.
  • The 1s float causes 100 Defiance bar damage, the pull causes 150 Defiance bar damage; the whole skill causes a total of 550 Defiance bar damage.
