Cleric: Darkness Domain - An evil/neutral domain for clerics that worship evil gods or gods of darkness. the opposite of the Light and cleric domain. It will have an ability to give temporary devils sight to party members, some necrotic spells, and even necromancy.
Druid: Circle of Pollution - Infernal, poison, and acid themed. All about terraforming and polluting the earth and creatures. I will make poison damage viable.

Rogue: Vampire Spawn - I really want to revised the Bloodcharmer rogue I wrote years ago but this time just go all the way by making the rogue into a balance vampire spawn. a blood based rogue
Sorcerer: Abyssal Bloodline - A sorcerer uses the powers of the abyss within its blood. This will have a new meta magic option to cast a spell innately which means it requires no components and can't be countered spelled. as well as a way to use demon ichor/demon flesh to recover sorcery points or gain abilities of a demon. The down side of using the demon ichor is if use too much too often you could mutate.
