  • The stability and stun break are only applied to the caster on skill activation, regardless of well location.
    • The rest of the effects begin applying immediately after the cast time has finished, which is when the first pulse starts.
  • The Aegis.png Aegis is reapplied every pulse.
  • Will go on full cooldown if it is interrupted before completion.
