# NFT Merge

* On this layer, you'll be able to Merge your existing NFT's Cards.
* You'll be able to take same generation NFT and combine them into one more powerful NFT of the same generation.
* Merging different generations is unavailable.

{% endhint %}

As Sandman Finance Team, we need to assure that merging wont affect equilibrium to the entire community.

### Merging Rules

* You'll be able to merge only 3 cards at a time.
* A card can only be merged once. This mean that once you get a merged card, it wont be eligible to marge again.
* Merging is only available with same generation cards.

### Merging Workflow

1. You'll go to the merging page. Will be published soon.
2. You'll select 3 unmerged cards.
3. Your 3 cards will be moved to the merging contract
4. Once the merge is finished, you'll need to claim your merged card.

### Merging formula - Version 1.0

For each skill, stacking power and experience on every card (3 cards) we'll calculated:

1. Maximum amount of that skill amongst all 3 cards.
2. Average amount of that skill amongst all 3 cards.
3. Each Merged Skil will follow this formula:

$$
MergedSkill = MaximumSkill + (AverageSkill / 2)
$$

Let's check an example:

| ----------- | -------- | ------- | --------- | ------------ | ------ | ------ | - | ------------- | ---------- |
