The idea
- Devils no longer summon contracts. Instead, they have an ability called "create forbidden fruit". This will take any consumable item held in-hand (food, medicine, anything you put in or on your body) and curse it. The next person to consume the item will lose their soul to the devil. The devils will need to be strategic when laying various trap items around the station.
- Devils gain various abilities as they consume more souls, such as jaunt and summon pitchfork. However, no more lesser devil and archdevil forms. Just more magic abilities. They also gradually gain more visual cues as they collect souls (skin turns red, horns, devil wings and tail, etc.)
- The devil's goal is to collect and maintain a certain number of souls
- Devils still have a bane and banishment. The soulless learn the true name of the devil upon having their soul stolen. To compensate for the fact that devils no longer have overpowered forms, you cannot kill them by killing them over and over again. They will only relinquish their souls upon being permanently killed.
The Soulless
- Upon losing their soul, the Soulless gets an objective: "[true devil name] has stolen your soul. Recover your soul, at any cost." The only way to recover a soul is to kill the devil that stole it. This means that all of the Devil's victims are going to have an objective to murder the fuck out of him and free valids to do it. The more souls the devil has, the more Soulless he's going to have gunning for him. It's reverse conversion. The objective is not a free license to grief, but it does mean that the Soulless can take matters into their own hands.
- Soulless people turn pale with white hair, making them very recognizable to the crew at a glance. The chaplain can spot Soulless by examining them.
- The soulless suffer from brain damage. They have difficulty using computers, as they will space out every now and then. They also gain a random trauma. However, they also randomly gain one of several random boons to give them a fighting chance against the devil. Boons include wielding two-handed weapons with one hand, x-ray vision, stun resist, toxin filter, regenerative coma, etc.
- If you die as a Soulless, your body turns to ash and you cannot be revived or cloned in any way.
- If a soulless is killed, the devil loses the soul they got from them. This means that the devil has to do everything in their power to keep the Soulless that are trying to murder them alive. It also means that a desperate crew might decide to kill off some Soulless to weaken the devil. Their objective will allow them to retaliate if this happens.
These mechanics would make devil into a unique and flavorful round type that isn't quite as apocalyptic as something like cult or ops, nor as cancerous as some failed conversion modes. We're really in need of some new main antags, and a reverse conversion mode is something that to my knowledge has never been done before.
Edit: A few ideas for abilities. Devil "levels up" with each soul stolen. If the devil loses a soul from a soulless dying, they lose an ability.
- Infernal jaunt. Basically the same as wizard jaunt, but a bit shorter and with fitting fire effects
- The devil gains glowing eyes, which make him slightly more noticable and grant night vision
- Soul Siphon. Channeled ability similar to changeling absorb. Steals the victim's soul. Channel speed scales with moodlets
- The devil's skin turns red, and becomes immune to fire.
- Summon pitchfork. Summons a highly robust two melee weapon on use. Hurts any non-soulless that tries to pick it up. Using it again recalls the same pitchfork, no matter where it is
- The devil grows horns and a tail, and can now breathe fire
- The devil grows wings, which function just like regular wings
- On death, the devil can take over the body of a soulless
- Toggle to suppress demonic traits, at some cost
- Some kind of stun for the devil
