Next it's time to roll Resilience. Anyone eating and drinking a full day's worth of rations don't have to roll. Everyone else makes an Average; Resilience check (got food or water) or Hard: Resilience (got neither food nor water). If people share their rations evenly reduce the difficulties by one but add a setback die (or two, if they found supplies for less than half the group). Advantage or Triumphs (or Threat and Despair) rolled on the Survival check above can add bonuses or penalties.

Failing the Resilience check with Threat upgrades the difficulty of all checks during the subsequent day by one. Failing with Advantage adds a setback die. Success means you're fine, but Threat inflicts strain.

But there's no threat of ever dying from complete lack of food and/or water. It's a hindrance to your actions, but not a threat to your life as it should be.

I'd be a little careful about inflicting Wounds directly from failed Resilience checks. That's too easy to fix with a stimpack or a Medicine check.

That was noted above. Changed to lowering Wound and Strain thresholds that can't be "healed" with medical actions.

I'd set a base difficulty (like Average or Hard), that is upgraded rather than increased, per day without primary source for survival not including air (water in case of humans). So it would start at R P ( P ) .

The base difficulty could be based on climate too, like Tatooine desert could easily start at a twice upgraded Daunted difficulty, whereas Endor may start at Average or perhaps even Easy...

Use threats to add setback dice to all checks, and/or strain threshold reduction. 1 = setback die to everything, additional X Threats cause ST reduction equal to whatever seems fitting.

Failures cause (additional) strain (threshold reduction) equal to total "uncancelled" failure symbols.

Despair causes wounds of appropriate amount depending on context, milieu and the like. Arguably it could also halve your Strain Threshold, or cause Strain equal to half Strain Threshold.

When you exceed your ST or ST is reduced to 1 or 0, you become unconscious and will die soon enough.

It easily becomes too much this.

Resilience checks plus strain threshold reduction.

I think you would lose some brawn if didn't eat after a time.

And certainly some setback die to after about 3 days without food

Do Droids need power sources in Star wars or do they have long power reserves?

Droids need to recharge, else they shutdown.

With the water at least your body recovers pretty quickly unlike with lack of food.

Lol, you could have resilience checks to drink your own urine

That is bad for you. All the salt and other waste material would just worsen the condition faster. Same with drinking salt water.

Yes i am sure it is quite unhealthy, but it still gives you more time before you die.

I guess in this RPG it would be something like.

You successfully drink your own urine you get +12 hours of survival, but suffer a critical injury

And if you failed the resilience check you would vomit and suffer 1 wound, multiple strain, and -6 hours of water

Each day without required amount of water causes 2 Strain and 1 Wound equal to the number of days without. On the 3rd day you suffer 6 Strain and 3 Wounds. Soak doesn't help. Medical aid doesn't help. You would thus quickly go unconscious but wouldn't die for a few days. Tough characters could last a week?

You might want to take environment into consideration too. As someone who spent a week in Death Valley, running out of water there is disastrous. You'd be lucky to make it 8 hours there.

It was mentioned before but take species into consideration. Mon Cals and Quarrens my suffer more but weequay would suffer much less in a desert environment because that is their homeworld. Do a little digging about the species homeworld.

More than a day but less than 3 I would simply add a setback to every roll the player makes.

for each day past three I would call for a hard resilience check with setbacks and boosts for species, environment, etc. (if they lack both food and water upgrade check once).

Success nothing happens

Advantage provides boost on next resilience or survival roll.

Failure deals wounds (can not be healed by medicine or stim packs)

Despair deals critical hits.

some days they will be ok, others they will take damage, eventually they will pass out and die. A bad roll could have them pass out on day 4 good rolls may let them go into the second week. This also spaces it so the part will pass out/ die at different times.

if they do fall unconcious be sure to have the Dinks come and take them to Yogurt (just to keep the story interesting)
