Kossuth's church is varied and chaotic since he takes no interest in its structure. As a result it is a collection of cults with each faction coming up with its own ethics, codes, morals, and teachings. Kossuth's symbol varys greatly from faction to faction, but is generally a depiction of fire. It is believed that if Kossuth's following (or any of the other Elemental Lords) were to somehow become unified he would become a very powerful force in the Realms. Something the other gods don't really wish to see happen. Of the four Elemental Lords, the best known and most feared are the cults of Kossuth, who are very powerful in Thay and the lands of the East.

Priest of Kossuth can be of any alignment, but most are evil, reveling in the destructive power of fire. They dress in whatever their faction deems approprate for the representation of their god. This is usually robes and long capes in reds, yellows, and oranges. They tend to use metal armor and shields, and use bills, swords, daggers, knives, and bludgeoning weapons.

Sphere selection is limited to Major access to All, Combat, Elemental-Fire, and Sun. Minor access is given to Charm, Divination, Healing, Necromantic, and Protection.
