# 6.5 MANEKINEKO NFT Lifespan, HP, and Durability

### Overview

MANEKINEKO NFTs have HP (Health Points) and Lifespan, both of which determine their active period and reward efficiency. Durability is a crucial parameter that affects both HP and Lifespan.

***

### 🧵 HP (Health Points)

#### **Overview**

HP represents short-term stamina consumed by actions such as Check-in. When HP decreases, reward efficiency drops, and at 0%, Check-ins become unavailable.

* HP consumption is 3% per Check-in for all MANEKINEKO NFTs.
* HP recovery cost varies depending on the NFT's **reward efficiency**.
* Higher Durability reduces HP consumption (but not recovery cost).
* NFTs with HP below 100% cannot be listed on the marketplace.

***

#### **HP Levels and Reward Efficiency**

| HP Level | Reward Rate | Status         |
| :------: | :---------: | -------------- |
|   75%+   |     100%    | Normal         |
|  50–75%  |     90%     | Slightly tired |
|  25–50%  |     70%     | Lowered        |
|  10–25%  |     40%     | Repair warning |
|   0–10%  |     20%     | Near dead      |
|    0%    | Unavailable | No Check-in    |

***

#### **HP Decrease Formula**

`HP Decrease = 3% × (1 - HP Reduction Rate)` \
`HP Reduction Rate = (Durability / 120) × 0.3`

**Examples:**

* Durability 60 → 15% reduction (2.55% consumed)
* Durability 120 → 30% reduction (2.1% consumed)

***

#### **HP Recovery and Repair Cost**

HP is restored using Econ. Recovery cost depends on several factors:

**Factors affecting HP recovery cost:**

* **NFT Rarity:** Higher rarity NFTs are designed to have lower repair costs relative to their reward output.
* **Reward Efficiency:** Higher earners have proportionally higher repair costs.
* **EVT Market Price:** Dynamically adjusted according to EVT price.

***

### ⏳ Lifespan

#### **Overview**

Lifespan represents the NFT's long-term activity span. It decreases each time EVT is earned. At 0% lifespan, the NFT becomes unusable. Durability reduces the rate of lifespan consumption.

***

#### **Consumption & Restrictions**

| Lifespan | Restrictions                            |
| :------: | --------------------------------------- |
|   <100%  | Cannot be listed or naturalized         |
|   <40%   | Cannot Breed                            |
|    0%    | Cannot Check-in or BIND (no token gain) |

***

#### **Lifespan Decrease Formula**

`Lifespan Loss = EVT Earned × Lifespan Coefficient (by rarity) × (1 - Durability Reduction Rate)` \
`Durability Reduction Rate = FLOOR(Durability / 10) × 1.2% (Max 20%)`

> **Note: FLOOR Function** Truncates decimals. Example: FLOOR(9.9) = 9, FLOOR(119 / 10) = 11.

Thus, Durability increases the reduction rate by 1.2% every 10 points (up to 20%).

***

#### **Additional Notes**

* **Lifespan Coefficient** is set per NFT rarity.
* Higher rarity NFTs consume less lifespan per EVT.
* **Durability Reduction Rate** adds further efficiency (max 20%).

**Examples:**

* Durability 100 → 12% reduction
* Durability 110 → 13.2% reduction
* Durability 170+ → max 20% reduction

***

### ♻️ Lifespan Recovery (Fusion)

Lifespan can be restored through fusion. Recovery amount and cost depend on the NFT or EVT used.

***

#### **Recovery Methods**

| Method           |  Amount  | Description                                                                 |
| ---------------- | :------: | --------------------------------------------------------------------------- |
| Use Common NFT   |    33%   | Burn a Common NFT                                                           |
| Use Uncommon NFT |   100%   | Full recovery (equivalent to 3 Commons)                                     |
| Use EVT          | Variable | Convert EVT to USD for recovery (conditions apply, available after EVT TGE) |

The NFT used as a recovery material must have both HP and lifespan (Life) at 100%.

***

#### **EVT Recovery Cost Formula**

Available after EVT's TGE.

**Conditions:**

* **For Common NFTs:** Always eligible to recover with EVT.
* **For Uncommon and above:** EVT can only be used if post-recovery lifespan is ≥90% and <100%.

`EVT Cost = Lifespan% × Base USD Value × EVT Market Rate`

**Base USD Values:**

| Recovery | Unit Used                  | Base Value |
| :------: | -------------------------- | :--------: |
|    33%   | 1 Common NFT               |     $50    |
|   100%   | 1 Uncommon NFT (3 Commons) |      -     |

Recovery cost is calculated based on the "Common Unit" regardless of market price.

***

#### **Examples**

* **Recover 50% for Common NFT:** `EVT Cost = 50% × $50 × EVT Rate`
* **Recover 40% for Uncommon NFT:** Use 1 Common NFT to recover to 93%, then recover 7% with EVT. `EVT Cost = 7% × $150 × EVT Rate`

***

#### **Additional Notes**

* 1 Common NFT = 33% recovery
* 1 Uncommon = 3 Commons = 100% recovery
* EVT cost is based on Common equivalency
* EVT-only recovery is available for Commons
* For Uncommons or higher, EVT can only supplement fusion to reach 100% (between 90–99%)

***

### ⚙️ Durability

#### **Overview**

Durability reduces both HP and Lifespan consumption. Unlike Charm or Luck, it doesn’t increase rewards directly. Instead, it makes NFTs more efficient by reducing operational costs.

***

#### **Effect Scope and Limits**

| Aspect        | Effect                          | Max Value |
| ------------- | ------------------------------- | --------- |
| Lifespan Loss | Reduces EVT-related consumption | 20%       |
| HP Loss       | Reduces Check-in HP usage       | 30%       |
| HP Recovery   | No effect                       | -         |

***

#### **Notes**

* Increase Durability by assigning level-up points.
* Every +10 Durability = +1.2% lifespan reduction rate.
* HP reduction capped at 30% (Durability 120).
