A bank of heavy yellowish green, poisonous fog rises up, slaying weak targets within the cloud, or inflicting damage on stronger targets:

Additionally this fog obscures sight, giving all creatures in the fog concealment (attackers have 20% miss chance). This portion of the spell affects all enemies, including red and purple named.


  • Cloudkill is a useful spell to use against most raid bosses as it's 20% concealment bonus does work on purple named. Though it won't deal any damage due to bosses' poison immunity, its long duration and useful debuff portion makes it a very desirable spell.
  • Cloudkill does not have any initial tic like Wall of Fire. Enemies must remain it in for at least 2 seconds for it to deal damage.
  • The duration is capped at caster level 20 like the damage. Maximum of 80 seconds.
  • Metamagics Empower, Maximize and Extend do not apply to Cloudkill. (This is very unusual as Empower and Maximize apply to almost every other damage dealing spell in the game.)
