This invocation summons masses of biting and stinging insects. One swarm is summoned for every three class levels. A swarm has a +4 base attack bonus (with an additional to hit bonus based on the caster's Charisma x 2) and deals 2d6 points of magical damage when it hits. A swarm dissipates after three rounds. Tenacious plague does not stack with itself - if the warlock uses this invocation while swarms still exist, the current swarms will be replaced with the new swarms.


  • This is not a direct attack and can be used with Walk Unseen without breaking invisibility.
  • Party members in the spell area will be affected in hardcore mode. However, the swarms are assigned when the spell is cast, so entering the area after casting is safe.
  • This invocation is much better than it may look at a first glance, since many defenses are bypassed: Stoneskin, Premonition, (Greater) Invisibility, and Concealment. It bypasses most (maybe all) forms of damage reduction.
  • This ability is not considered a hostile spell for the purpose of dispelling the Walk Unseen ability, but it will take the caster out of stealth mode.
