# 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.

***

#### **Using collaboration Common as material**

When you use an eligible collaboration Common as material for lifespan recovery, that material NFT is burned and its skin is automatically transferred to the recipient. You cannot recover lifespan without also transferring the skin.

The transferred skin replaces the recipient's current appearance, including any existing skin. You cannot undo this change or save, restore, or switch back to a previous skin. Each eligible material NFT can transfer its skin only once. A skin received this way cannot be passed on to another MANEKINEKO.

Only the skin transfers. The recipient keeps its own OG or Origin provenance, rarity, and P rank. The material's abilities and lineage do not transfer. Lifespan recovery follows the normal Fusion rules.

#### **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) |

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

***

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

**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).

### 🎮 Play Strategy Tips

* **Increase Durability** → reduce consumption and save maintenance.
* **Use Common Fusion** → extend lifespan.
* **HP always drops 3%** → remember regular repairs.
