### 🧬 What XP Is Used For

XP is used to:

* Increase Terry level
* Unlock additional skill points
* Access higher long-term potential

XP does **not** affect leaderboards or rewards directly.

### 🟦 XP Base Multiplier (Rarity)

Each Terry has a fixed XP multiplier based on its rarity.

| Rarity    | XP Multiplier |
| --------- | ------------- |
| Basic     | 1.00×         |
| Common    | 2.00×         |
| Rare      | 3.00×         |
| Epic      | 4.00×         |
| Legendary | 5.00×         |
| Mythic    | 6.00×         |
| Ultimate  | 7.00×         |

Higher rarity Terries earn XP faster, but require more total XP to reach max level.

### 🧠 Ambition (XP Skill)

Ambition increases all XP earned.

* Applies to reviews, quests, achievements, and **any** XP-based action
* Each point adds a fixed percentage bonus
* Scales linearly and predictably

***

### 🧮 XP Multiplier Formula

```
Final XP Multiplier
= Rarity XP Multiplier × (1 + Ambition × Ambition_Per_Level)
```

#### Example

* Terry rarity: Rare → 3.00×
* Ambition: 10
* Ambition per level: 0.04

```
Final XP Multiplier =
3.00 × (1 + 10 × 0.04)
= 4.20×
```

#### **XP Reward Calculation**

```
Final XP =
Base XP × Final XP Multiplier 

If base XP = 50 then 50 × 4.20 = 210 XP
```

***

### 🧮 XP Reward Calculation (Simplified)

```
Final XP =
Base XP × (Rarity XP Multiplier + Ambition Bonus + Other XP Boosts (if any))
```
