Health, hunger & thirst

All four bars go from 0 to 100.

Hunger and thirst

• Hunger drops by 1 every 10 seconds, so a full stomach lasts about 17 minutes of play.
• Thirst drops faster: a full bar lasts about 12 minutes.
• If either hits 0 you lose health: 1 point every 2 seconds.
• Eat and drink to refill them: All items lists what each one restores. Pin them to the hotbar from the bag so they're one tap away.

Health

• You heal slowly on your own (1 point every 4 seconds) while hunger and thirst are both above 60.
• Bandages and first aid kits heal straight away.
• Armor takes a share off every bite.
• At 0 health you're bitten. See Getting bitten.

Energy

• Every swing costs energy (8 for fast weapons, 11 for heavy ones) and you need at least 6 to swing. A roll costs 18.
• Energy refills quickly when you stop spending it for a moment.
