Chapter 4
Status-heavy encounters and first difficulty spike—gear and resist checks.
Summary
Escort the supply caravan across Solaris Dunes, purge sandstorm obelisks, and reclaim the Oasis Spire from the corrupted guardian. Recommended level: 12–14 with memory cap 20–22.
Branches & Choices
- Choose the Caravan Route to keep vendors safe and earn affinity.
- Take the Ruins Shortcut for rarer loot at the cost of tougher mobs.

- Equip Stun Barrier or Shock Harness on frontliners to nullify the guardian’s Sand Tomb stun.
- Carry 5+ Remedy Disks and 3 Ether Charge for SP recovery in the Ruins shortcut.
- Slot a digimon with AoE cleanse (e.g., Salamon → Gatomon) to remove Curse stacks from obelisk elites.
