Learn how to upgrade your player officer's rank and stats in Astral Chain. Discover the best upgrades for your X-Baton and Legatus to dominate combat.
Hey there! So, besides making your Legions stronger, you can also beef up your own character, the officer. It's pretty straightforward, and honestly, a good way to boost your survivability and effectiveness in combat.
Officer Upgrades
As you play through the game and complete missions (called Files), you'll earn Duty Points. These points act as experience for your officer rank. Leveling up your rank doesn't just give you a little health boost each time, but you'll also snag some cool cosmetic gear along the way. It's a nice little reward for your efforts!

| Officer | 18,000 | 700 | Police Hat |
| Officer + | 40,000 | 800 | Lappy Cap |
| Specialist | 80,000 | 900 | Marie's Glasses |
| Specialist + | 120,000 | 1000 | Perching Raven |

X-Baton and Legatus Upgrades
Now, when it comes to spending your hard-earned materials and money, I'd seriously consider prioritizing your X-Baton and Legatus upgrades. You're constantly using your baton in fights, way more than you're switching Legions, so making it hit harder and faster is a big win. The Legatus itself is less crucial, but its upgrades can still be super helpful. You might find yourself relying less on the AED (your emergency shield) as you get better, but the Limiter upgrades are definitely worth it for boosting your overall combat potential.

Tips: Focus on upgrading your X-Baton first, as you'll use it constantly. The Legatus upgrades are good too, especially for the Limiter, but the baton is your bread and butter.
