Prerequisite Gear Checklist

Before you even think about diving into Tidefall, make sure your loadout is ready. You cannot survive this trip with basic gear:

• Boat: Speedboat or better to reach coordinates quickly
• Survival Gear: Advanced Oxygen Tank is highly recommended
• Pro Tip: If you don’t have the Advanced Tank, use the Water Bubble spell/item, but it’s riskier if you get lost

Step-by-Step Path to Tidefall

1. Head to the Coordinates: Pilot your boat to (3138, 132, 910) – this is the entrance to the Underwater Cave zone
2. The Dive: Equip your diving gear and swim straight down
