# Scientist

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:
- [**Flora Cultivator**]($content/machines/flora_cultivator)
- [**DNA Modifier**]($content/machines/dna_modifier)
- [**Gene Isolator**]($content/machines/gene_isolator)
- [**Genetic Analyzer**]($content/machines/genetic_analyzer)
- [**Incubator**]($content/machines/incubator)

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**]($content/items/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

1. **Obtain an Unemployed Villager**
- Breed villagers or find naturally spawned unemployed villagers
- Ensure the villager has not claimed a different job site block

2. **Place a Job Site Block**
- Place one of the accepted machines ([Genetic Analyzer]($content/machines/genetic_analyzer), [DNA Modifier]($content/machines/dna_modifier), etc.) near the villager
- The villager must be able to pathfind to the machine

3. **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**]($content/items/syringe) 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
