Cloudkill

Cloudkill was an Conjuration or Evocation spell that filled a area with a extremely lethal cloud.

Effect
Cloudkill would release a yellowish green cloud that was heavier then air so it would always sink to the ground or holes. When cast the cloud would travel away from the caster and could be broken apart by strong winds or dens vegetation. The cloud would instantly kill "weak" creatures and greatly injure stronger creatures with its poison. It would not mater if the creature held its breath as the poison would still effect it.

After the Spellplague the cloud would just harm targets and could be moved by the wizard whom also needed to sustain it. The post sundering version held some of the same aspects of the older versions like being heavy and affecting creatures whom hold there breath or don't need to breath. This version also lasted for 10 minutes and moved 10 feet per 6 seconds away from the caster and if used with a higher spell level would cause more damage.

Components
Only vocal and somatic components where needed.
