The Scientist is a custom villager profession added by Jurassic Saga, specializing in genetic engineering equipment and rare cosmetic genes. These lab-coated experts are essential for obtaining hard-to-find genes and genetic engineering supplies without extensive resource gathering.
Appearance
- White lab coat with blue wrists
- Small green dot on the bottom right of the coat's front
- Lab coat is open all the way down
- Professional scientific appearance distinct from vanilla villager professions
Job Site Block
Scientists require one of the following machines as their job site block:
Place any of these machines near an unemployed villager to convert them into a Scientist.
Trading
Scientists offer trades that become more valuable as you level them up through trading.
Level 1 (Novice)
Available Trades:
- Syringe — Essential tool for gene extraction and egg fertilization
- Empty Test Tube — Basic laboratory equipment
Use Case: Starting genetic engineering work and basic lab supplies.
Level 2 (Apprentice)
Available Trades:
- Basic Genes — Common functional and cosmetic genes
Use Case: Obtaining genes without farming specific mobs.
Level 3 (Journeyman)
Available Trades:
- More Genes — Expanded selection of functional and cosmetic genes
- Rarer Gene Variants — Less common genetic modifications
Use Case: Advanced genetic customization and creature modification.
Level 4 (Expert)
Available Trades:
- Chaos Effect Gene — Exclusive cosmetic gene with unique appearance
- Legacy Gene — Classic cosmetic gene variant
- Special Cosmetic Genes — Rare and unique visual modifications
Use Case: Creating creatures with the rarest and most distinctive appearances.
Level 5 (Master)
Available Trades:
- Random DNA — A random selected Species DNA, quality varies from 2% to 27%
Use Case: A easier way to obtain a certain species DNA.
Finding Scientists
Converting Villagers
-
Obtain an Unemployed Villager
- Breed villagers or find naturally spawned unemployed villagers
- Ensure the villager has not claimed a different job site block
-
Place a Job Site Block
- Place one of the accepted machines (Genetic Analyzer, DNA Modifier, etc.) near the villager
- The villager must be able to pathfind to the machine
-
Confirmation
- The villager will walk to the machine and claim it as their job site
- Their appearance will change to the Scientist outfit
- They will begin offering Scientist trades
Village Generation
Scientists may naturally generate in villages if genetic engineering machines are present during world generation (behavior may vary).
Trading Tips
- Level Up Efficiently: Trade frequently to unlock higher-tier gene trades quickly
- Multiple Scientists: Create several Scientists to access different gene trades and refresh stock
- Emerald Conservation: Stock up on emeralds before attempting to purchase rare genes
- Gene Comparison: Compare Scientist trades with mob extraction using Syringes to find the most efficient method
- Chaos & Legacy Priority: Save emeralds for Level 4 trades, as Chaos Effect and Legacy genes cannot be obtained any other way
Strategy
Early Game
Focus on Level 1 trades for Syringes to jumpstart your genetic engineering without crafting resources.
Mid Game
Use Level 2-3 trades to supplement gene collection, especially for genes from hard-to-find mobs.
Late Game
Invest in Level 4 trades for exclusive Chaos Effect and Legacy genes that define your creature collection's appearance.
Trivia
- The Scientist profession is Jurassic Saga's equivalent to vanilla professions like Armorer or Toolsmith
- The white lab coat design is inspired by the geneticists and scientists throughout the Jurassic Park franchise
- Scientists are the only source of Chaos Effect and Legacy genes, making them essential for completionist players
- The green dot on the lab coat may represent an ID badge or security clearance marker
- Unlike vanilla villagers who work during the day, Scientists thematically represent 24/7 laboratory operations
