Deco System
Deco System - upgrade Sunglasses, Pumpkin or Cat Ears through three combine pages for stat bonuses up to v3.
Upgrade your Sunglasses - or other decorative accessories - through the Deco Upgrade window. 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 200,000 CP - the accessory itself is not lost.
