Revision 8

Overview

Starsand Island has five professions, each with its own mentor NPC, five certification tiers, and unique unlocks. Professions are the primary progression system — advancing tiers unlocks new blueprints, tools, skills, crops, animals, and recipes. You can pursue all five professions simultaneously; there is no restriction on picking one.

Tier progression

Each profession advances through five tiers:

1. Apprentice — Starting tier. Unlocked by talking to the mentor for the first time.

2. Junior — First certification quest. Expands basic options.

3. Intermediate — Second certification. Unlocks significant new mechanics (sprinklers, Breeding House, Realm Box).

4. Senior — Third certification. Opens high-value content (rare crops, mount rentals, advanced tools).

5. Expert — Final certification. Unlocks the rarest items and abilities in each profession.

To advance a tier, complete the certification quest from your mentor. These quests require demonstrating competence in that profession — for example, the Farming Junior quest might ask you to harvest a certain number of crops, while the Exploration Senior quest involves defeating a specific boss.

Workpedia

Each profession has a Workpedia page accessible from your phone. The Workpedia tracks skills you can unlock at each level, shows your current progress, and lists the requirements for the next tier. It functions as both a skill tree and a reference guide for what each profession offers.

Tips

• Pursue all five professions simultaneously. There is no penalty or exclusion for doing so, and many unlock synergies exist across professions.

• Check your Workpedia regularly to see what skills are available at your current tier.

• Crafting is the most important profession to advance early — nearly every other profession depends on crafted tools and stations.

• The Intermediate tier is a major power spike across all professions. Push to Intermediate in your primary profession as soon as possible.
