Talk:Damage over time/@comment-80.108.245.22-20120611110447

When does the first tick apply? As in, when I attack every 0.4 seconds with a Teemo or Executioner's Calling or Blessing of the Liz, will the first tick still deal damage or does it happen after one second, but getting reapllied before the tick, thus negating damage? Or will the tick-timer continue to count, even though the debuff was reapplied?
