Tune hunger, thirst, body temperature, carry weight and stamina, and make the food, drink and clothing that keep players alive.

Survival

With survival on, every player carries three bars on top of health and mana: hunger, thirst and body temperature. Hunger and thirst drain over time, temperature drifts toward the air around the player, and a player who lets any of them slip picks up a condition — Hungry, Cold, Dehydrated — that costs them health, stamina, speed or stats until they fix it.

This page is the full reference. For the weather and seasons that set the air temperature, see Environment and Weather Climates.

Setting It Up#

Make sure Survival is on in World → Features (it is on by default).
Open Database → Characters, open any character and go to the Survival tab. Set the starting vitals and how fast hunger and thirst drain. The Time Estimates box tells you how long a full bar lasts.
On the Penalties tab, set what each condition does. Leave the defaults if you just want the standard feel.
Click Save Changes. Saving a character writes its Survival and Penalties tabs as the settings for the whole world (see the gotchas).
Author food and drink in Database → Items: pick type Food, and on the Stats tab fill in Hunger Restore and Thirst Restore.
If your world has cold or hot regions, give those climates a Temperature offset and give players a way to fight it — Warmth / Heat Resist on armour, a Warmth affix, or a hot meal with Warmth on Use.
Publish. The live server picks up the new survival settings on publish without a restart.

How the Bars Work#

Bar	Range	What moves it
Hunger	0–100	Drains by Hunger Decay / sec all the time. Eating refills it.
Thirst	0–100	Drains by Thirst Decay / sec all the time. Drinking refills it.
Body temperature	Shown in degrees; comfortable between 35° and 65°	Drifts toward the air temperature where the player stands, closing about 2% of the gap every second — roughly two-thirds of the way in under a minute.
Stamina	0 to the character's max stamina	Refills by Stamina Regen / sec once the player is out of combat. Spent by abilities with a stamina cost and, if you turn it on, by running.

At the defaults a full hunger bar lasts about 33 minutes and a full thirst bar about 21 minutes.

The air temperature#

The air temperature a player feels is built from four parts, added together:

Part	Values
Time of day	Night 30, Dawn 40, Morning 48, Noon 55, Afternoon 58, Dusk 45
Weather	Clear 0, Cloudy −3, Fog −5, Rain −8, Storm −12, Snow −20, Blizzard −30, Sandstorm +15, Heatwave +18
Season	Spring 0, Summer +12, Autumn −5, Winter −18
Climate	The Temperature offset of the climate the player is standing in

Then the player's own gear shifts it: every point of Warmth makes the air feel half a degree warmer, and every point of Heat Resist makes it feel half a degree cooler. A winter night in a snowstorm is 30 − 18 − 20 = −8°: a player with no warmth will end up Freezing.

Conditions#

A condition switches on the moment its threshold is crossed and off the moment the player recovers.

Condition	When	Default cost
Hungry	Hunger below 25	−2 attack, −1 stamina/s, 95% speed
Starving	Hunger at 0	−5 attack, −3 defense, −1 HP/s, −3 stamina/s, 70% speed. Max stamina is also halved.
Thirsty	Thirst below 25	−2 magic power, −1 MP/s, −1 stamina/s, 95% speed
Dehydrated	Thirst at 0	−5 magic power, −3 attack, −1.5 HP/s, −2 MP/s, −4 stamina/s, 60% speed
Cold	Body temperature below 35°	−0.5 HP/s, −1 stamina/s, 85% speed
Freezing	Below 20°	−2 HP/s, −3 stamina/s, 50% speed
Hot	Above 65°	−0.5 HP/s, −2 stamina/s, 90% speed
Overheating	Above 80°	−2 HP/s, −4 stamina/s, 60% speed
Overweight	Carrying 80% of the character's Carry	−2 stamina/s, 75% speed
Encumbered	Carrying 100% of Carry or more	−5 stamina/s, 30% speed
Well Fed	Eating to 90+ hunger; ends below 70	A marker only — no bonus
Hydrated	Drinking to 90+ thirst; ends below 70	A marker only — no bonus

Whenever thirst is below 25, the player's health also cannot heal past half their max HP.

Survival Tab Fields#

Field	What it does
Starting Hunger / Starting Thirst	What a brand-new character starts with (0–100).
Starting Body Temp	A new character's starting temperature. 50 is comfortable.
Hunger Decay / sec	Hunger lost per real second. Default 0.05. 0 = hunger never drops.
Thirst Decay / sec	Thirst lost per real second. Default 0.08.
Stamina Regen / sec	Stamina regained per second out of combat. Default 5.
HP Regen Flat / sec and HP Regen % MaxHP / sec	Out-of-combat health regeneration: the flat amount plus that fraction of max HP (0.01 = 1%).
MP Regen Flat / sec and MP Regen % MaxMP / sec	The same for mana (default 1 + 2% of max MP).
Regen Delay (ms)	How long after the last hit before HP, MP and stamina start regenerating. Default 4000.

The Harvesting and Misc groups on the same tab tune gathering and duels, not survival.

Penalties Tab Fields#

One row per condition. Negative numbers hurt.

Column	What it does
HP/s, MP/s, STA/s	Health, mana and stamina gained or lost every second the condition is on.
Speed x	Movement speed multiplier. 1 = normal, 0.5 = half speed. Values above 1 are ignored.
ATK, DEF, MPOW, MRES	Flat changes to attack, defense, magic power and magic resist while the condition lasts.

Reset penalties to defaults puts every row back to the table above.

Food and Drink Fields#

On an item's Stats tab:

Field	Item types	What it does
Hunger Restore	Food, Potion / Poison	Hunger given back when used (0–100).
Thirst Restore	Food, Potion / Poison	Thirst given back when used (0–100).
Warmth on Use	Food	Body temperature change, in degrees, the moment it is eaten or drunk: a hot stew `10`, an iced drink `-10`. Afterwards body temperature drifts back toward the weather as usual.
Warmth / Heat Resist	Armour	While worn: every point of Warmth makes the air feel half a degree warmer, every point of Heat Resist half a degree cooler. Adds to affixes and the character's base values.
HP / MP / Stamina Restore	Potion / Poison	Health, mana or stamina restored, in points or % of max. Negative values drain.
Granted Passives (Advanced tab)	Food, Potion / Poison	Timed passives the item grants — use these for a real "well fed" buff.

A Food item with every restore left at 0 still works: it restores 16 + 8 × tier hunger and 4 + 2 × tier thirst. To make a meal that also heals or refills stamina, make it a Potion / Poison item instead — Food items do not show the HP, MP and stamina fields.

Gotchas#

One set of survival settings per world. The Survival and Penalties tabs appear on every character, but the world uses whichever character you saved last. Keep them identical on every character, or edit them on one character only.

Turning Survival off stops the survival parts only. Hunger and thirst stop draining, temperature stops moving, no conditions apply, and the survival bars disappear from the HUD. Natural HP, MP and stamina regeneration keep working.

Warmth and Warmth on Use share one value. An item is either worn (armour: Warmth) or used up (food: Warmth on Use). Items saved before this field was stored read 0 — open and re-save them after setting the value.

Buildings are not shelter. The engine does not treat indoors as warmer. To make an interior or a hot spring comfortable, cover it with a climate whose Temperature offset brings it into the 35–65° band.

There is no resting. Sitting or sleeping does not restore hunger or thirst. HP, MP and stamina come back on their own once the player is out of combat.

Stamina does not regenerate in combat. It waits for the same Regen Delay as health.

Running only drains stamina if you turn it on. Running Drains Stamina in Combat Config → Stamina is off by default. When on, a runner who hits 0 stamina drops to Winded Speed Multiplier (50%) until they recover to the Resume Threshold (30%).

Weather only changes temperature. A heatwave makes players hot, and heat can kill them, but it does not make thirst drain faster by itself.

Dying to survival damage respawns the player with half hunger, half thirst, half stamina and a comfortable temperature.

Survival conditions are not status effects you author. They do not appear in Database → Status Effects; the Penalties tab is where you tune them. See Status Effects.
