Phase 2: Outward Expansion
- Explore along major roads between settlements

- Target TPs near diverse creature spawns
- Visit Gamma TP (Milo’s location for PTech dailies)
Phase 3: Underground & Instances
- Access Arkadia Underground via TP dropdown menu
- Unlock underground TPs for mining routes

Planet-Specific Tips
- The Underground is Arkadia’s crown jewel — Once you have mining skills, explore it for unique resources
- Treasure maps are real — Don’t vendor them. Research their value or save them
- Triple-dip every hunt — IFN mission + Codex + daily mission on the same mob = maximum efficiency
- Start Aakas early — Key 1 is beginner-friendly with max boss HP of 1,500. Don’t wait until endgame
- The Smuggler questline is worth it — Unlocks unique instances and the UL Smuggler Plate armor progression
- Arkadia Insignias are currency — Dailies and weeklies reward Insignias used for gear upgrades. Do them consistently
- Keys 8-9 have sparse data — Community knowledge is limited on these levels. If you run them, consider contributing findings
- Moon access — Arkadia has a moon with additional content, accessible via space station
- Sicarius Nest is a team encounter — The 187,500 HP Broodmother is the hardest boss on Arkadia. Don’t solo it
- IFN Spec Ops Armor — Complete the Special Operations chain and collect materials to upgrade to Perfected tier
