- Grace Period: By default, you have 30 ticks before taking air-drowning damage.
- Turtle Helmet: Wearing a Turtle Helmet significantly extends your survival time on land to 300 Ticks.
- Respiration: The Respiration enchantment on your helmet reduces the drowning damage taken per second.
🪣 Starting Aid
Every player receives a Water Bucket upon joining for the first time and after every respawn.
