Chills is a term used for effects that mimic Elementalism's Freeze ability:

  1. The first application strips the target's fire potion defence (if the target has that active).
  2. Without the defence, the target receives the shivering affliction.
  3. If they are still shivering, the next chill will cause the frozen affliction.

Note: one cannot reapply the fire potion defence until one has cured themselves of shivering and frozen.
