Buffs

Different game conditions can impose special temporary effects on you and your peasants.

It's important to remember that buffs and debuffs don't only affect you and your peasants — they also affect enemies. Read the description of any buff or debuff in the corresponding tooltip in the peasant or feudal lord's inventory menu.

Buffs
Whipped	Happiness is reduced by 10. Movement, attack and production speed is increased by 30%. (Active on peasants when they are whipped. Source: Whip)
Road	Movement speed is increased by 50%. (Active when moving on a road.)
Rest	The Well Rested effect is gained over time. (Active when a peasant got plenty of rest (has 4 levels, and each level increases the overall buff effect).)
Well Rested	Each level grants +2 points of happiness, +10% stamina recovery speed, +3% damage, +5% critical hit chance, +5% chance to craft higher-quality equipment.
Feudal Lord on the Throne	Increases happiness by 5 (Stone Throne) / 10 (Ivory Throne) per Feudal. (Active when the feudal lord is sitting on the throne.)
Invulnerability	Character can't die. At the end of the action, half of the health is restored. (Source: Berserker)
Warmed Up	Immune to the "Frozen" effect. Health regeneration is doubled. (Active in a winter snowstorm if you warm up by a fire or in bed.)
Careful	The character does not activate traps.
Light Set	90% chance to dodge melee attacks and ability to kill an enemy at less than 25% health.
Medium Set	Shots wound enemies. A wound reduces movement speed by 30% for 15 seconds. A repeat shot that hits a wounded enemy deals 500 additional damage.
Heavy Set	Lets you ignore enemy shield blocks and grants a 20% chance to stun an enemy with melee attacks. 20% of melee damage to enemies will also be returned as health.
Druid Among the Trees	Movement speed is increased by 50% (doesn't stack with the "Road" effect). Health regeneration is increased by 100%. Stamina recovery rate is increased by 30%. Trees feel like a roof overhead for druids.
Debuffs
Darkness	Movement, attack, and production speed is reduced by 30%. (Active when moving through unlit areas at night.)
Wetland	Movement speed is reduced by 30%. (Active when moving through a floodplain.)
Trap	Movement speed is reduced by 30%. (Active when moving through a trap.)
Wet	Hunger rate doubled. Get under a roof to remove this effect. (Active when not under a roof when it's raining.)
Frozen	The character takes damage over time. (1.5% of Max HP every game minute. Active if you are in a winter snowstorm if you are not under a roof and don't have the "Warmed Up" buff.)
Wound	Movement speed is reduced by 30%. A repeat wound will deal 500 additional damage.
Burning	The character loses 3% of their health per second.
