This is obviously heavily inspired by MistyDW's Doomsday Countdown over on MTS
Dark shadows gather over your world. The forces of hell rise every night, cutting your town off from the outside world. Only the sun brings salvation. You have no idea if it’s like this everywhere, but you are determined to survive – and perhaps escape. But until you can do that, you must resist the darkness.
This Challenge uses the D&D skill- and rolling system (to an extent). That means, You get a Difficulty Score (DC) that you must meet or exceed to pass a check. To do that, you must roll a 20-sided die (or use an online dice rolling app). You will get different modifiers for different skills your sim has (meaning you add to your roll)
You gain 1 modifier point per two skill levels. That means, if you are level 6 in a skill, you would add 3 to your roll.
Some circumstances may give you Disadvantage, in which case you roll twice and take the lower result.
Skills and what they modify:
Martial Arts – Combat
Athletic – Physical Fortitude
Gardening – Herbology, Survival (includes tracking etc.)
Alchemy, Cooking – Identifying poisons, Purifying food sources etc.
Charisma – Anything social
Logic – Various mental things, and mental fortitude
Handiness – self-explanatory
Science – Medical checks, anything to do with technology
The Sanity System:
Some events may cause your Sim to lose a sanity level. That puts them at a lower sanity level, effects of which are detailed below. Your sim may recover one sanity level by spending an entire day only doing what they enjoy (meaning generic fun activities, or more specific to the Sim in question. Like, a Loves the Outdoors sim may go for a walk, a virtuoso may listen to music etc). During this recovery period, the Sim may not perform ANY skill building activities or chores.
The Sanity effects STACK, which means if you’re at a level 3, you suffer the effects of levels 5, 4 and 3.
Sanity levels:
6 – You’re fine and function normally.
5 – You’re feeling paranoid, and will not interact with anyone below Good Friends level.
4 – You feel a lack of motivation and energy. Once your Sim fills their energy bar by sleeping, Use testingcheats to drag it back to the middle.
3. You feel scared all the time. Your Sim may not be alone in a room, excluding bathroom activities. If they are, roll a Logic check (DC 12). On a fail, you suffer an additional Sanity loss.
2. Your Sim now has disadvantage on every check they make.
1. The Darkness surrounds you. If your Sim does not recover a Sanity level by the next Dawn, the shadows consume them and they die.
Possession:
Throughout your story, you may come in contact with possessed Sims, or even get one of your own possessed. When in this state, your Sim will be violent to everyone other than possessed sims and attack them (Spar or Fight).
To recover, you must isolate the possessed sim from anything and everything. Lock them in a small 4x4 room alone and without any objects inside for 24 hours. If they are still alive after that period, they are considered liberated from Possession, but are at Sanity Level 3.
Combat and Injury:
If your Sim wins a Spar/Fight, you’re fine. If you lose, roll on this table to see what injury they suffer: (No modifiers for this roll!)
Combat with NPCs may also be a Martial Arts check
1. Blunt force head trauma. You may not participate in any mental activities for 24 hours.
2. Ankle Sprain. You must walk everywhere and your cannot stand for longer than three hours at a time
3. Heavy Blood Loss. Use testingcheats to drain your Sim’s energy bar so they pass out. Roll an Athletic check (DC 14). If you fail, your Sim is out of commission for the rest of the week (3 days if it happens on a Sunday)
4. Broken Leg. Your Sim may not perform any actions that involve standing or moving around a lot for three days.
5. Internal Organ Damage. Another Sim must perform a DC 16 Science check, or the affected Sim perishes.
6. Blow to the Stomach. Your Sim has vomited all their stomach contents. Drag their hunger bar into the red.
Elixirs:
At some points in the story, you will be allowed to visit the Elixir Consignment store. In addition to their ingame effects, Elixirs have the following benefits:
Ad Nauseum: cures poison
Vial of Potent Bliss: Lets your reroll one check per elixir
Cure Elixir: Restores 1 Sanity level and heals 1 Injury
Essence of Magic: Gives your next Logic check a +2
Potent Invigorating Elixir: Gives the drinker a +2 on any mental check until the next Dawn
Potent Cure Elixir: Restores a Sim to level 6 Sanity and Cures all Injuries. Will also remove Possession.
Setting up:
Create a minimum of four YA sims and built them a home. You may use money cheats to build, but reset your funds to 5.000 when you’re done.
You will need the Martial Arts skill, so use buydebug to get the training dummy.
You may use buydebug to buy 3 fully mature base game plants.
General Rules:
All your sims must be human.
You can only cook with what you have. That means, if a meal has a price next to it, you can’t make it. No quick meals!
If you eat anything of normal or lower quality, roll a D20. 1-5: You’re poisoned and will die within three days unless cured. 6-10: You vomit your food. Drag your hunger bar back to where it was before the meal. 11-20: you’re fine.
You cannot go outside during the night. If you do, you die. The same applies to Storms, Rain etc. Basically anything that obscures the sun.
You may not use Build/buy outside of specified events once the game starts.
You may not use any stores (Including Consignment Stores) outside of specified events.
If a child is born during the game, Roll a D20. If you roll below 10, the child is born with the Evil trait.
The Evil trait attracts the shadows. If you have it, roll a Logic check (DC 12) every Sunday. If you fail, you get possessed.
Play with the lunar cycle. If your sim gets bitten by a zombie, they are considered poisoned and will die unless cured withtin three days.
When socializing with NPC sims, Roll a D20. Below a 5, they are Possessed and will attack you. You must fight them.
If you find a seed in the wild, Roll a Gardening check (DC10). If you fail, the seed is corrupted and unusable.
