  • Does not stack with chance to miss % of other insect swarm.
  • Unlike a lot of other DoT spells which deal damage every 3 seconds, Insect Swarm deals damage every 2 seconds, meaning 6 ticks will occur in its duration of 12 seconds (7 over 14 seconds if you have Nature's Splendor).



Improved Insect Swarm: Increases your damage done by your Wrath spell to targets afflicted by your Insect Swarm by 1-3%, and increases the critical strike chance of your Starfire spell by 1-3% on targets afflicted by your Moonfire spell.

Tips and Tactics

  • The talent is useful when used in conjunction with Moonfire. In addition, it's a cheap DoT that gains 120% from your +spell damage, which makes it desirable for certain balance builds and one of the most mana-efficient DoTs in the game.
  • In a raiding perspective the damage mitigation with the chance to miss helps with the survival of the main tank.
  • Unlike most (all?) Druid spells, Insect Swarm does not interrupt the swing timer. [1]

Patch changes

  • World of Warcraft: Wrath of the Lich King/ World of Warcraft: Cataclysm Patch 4.0.1 (12-Oct-2010): No longer a talent, available to all druids.
  • World of Warcraft: Wrath of the Lich King Patch 3.1.0 (14-Apr-2009): The bonus damage from spell power on this damage-over-time ability has been increased significantly to match similar spells on other classes (from 76% to 120%).
  • World of Warcraft: Wrath of the Lich King Patch 3.0.3 (04-Nov-2008): Tooltip corrected to indicate it does not affect hit chance with spells.
