Luca Arbor (The Sacred World Tree)

The 40-Level Planet Growth & Progression Core

The Luca Arbor is the heart and soul of your miniature planetoid. Rooted at the geographic pole of your world, this celestial tree grows as you cultivate crops, befriend neighbors, and fulfill Starsea commissions. Each tree level expands your planetoid surface area, unlocks new terrain biomes, increases your neighbor resident cap, and opens advanced life-sim features.

Planetary Currencies & Economic Flow

Dough, Loomi, Miraprint & Omni-Vouchers Master Guide
