Pandemic

The "Pandemic" mechanic in WoW is a crucial element for min-maxing. It allows you to add 30% of the normal duration of a DoT (Damage over Time) or HoT (Heal over Time) to its new application, effectively extending it. This enables you to fully focus on your cooldowns or other important windows without having to spend a global cooldown on something that doesn't contribute significantly to direct damage or healing.

• You cast Purge the Wicked on a target, with a baseline duration of 20 seconds.
  • The Pandemic threshold is 30% of 20 seconds. We calculate this as 20 * 0.3 = 6, so the threshold is 6 seconds.
  • If you cast Purge the Wicked again when the active one has 6 seconds or less remaining on its duration, that time will be added to the new Purge the Wicked, resulting in a new duration of more than 20 seconds.
  • If you cast Purge the Wicked when the active one has more than 6 seconds remaining, the total duration is refreshed to 26 seconds, since the maximum duration can’t exceed more than 130% of the base duration.
