Sunglasses Upgrade System
Upgrade Sunglasses (and other decorative accessories like Pumpkin or Cat Ears) at the Elder NPC for stat bonuses up to v3.

Upgrade your Sunglasses - or other decorative accessories - at the Elder NPC in your faction city. Each tier adds stronger stat bonuses on top of the base.
Compatible Accessories
You can use any of these as the v0 → v1 base:
- Sunglasses
- Pumpkin
- Cat Ears
If the upgrade fails you only lose 1B Silver and 1K CP - the accessory itself is not lost.
