# Summoning Heroes

In **Heroes TD**, players can summon new **NFT Heroes** using 2 **NFT Heroes**. Some **HTD** will be consumed in the process. 

The newly summoned hero will bear the exclusive traits from the 2 summoners. More details can be found here: 

## **Summoning Rule**

* Summoned NFT Heroes **can't be summoned with the NFT Heroes that summoned him**. 
* NFT Heroes **summoned by one or two same NFT Heroes will not be able to summon together**.
* 1 NFT Hero can only be used to summon **7 times**.

*For example:*

**Hero A** + **Hero B** summoned **Hero AB1 , AB2 , AB3 , AB4**...

**Hero A** + **Hero C** summoned **Hero AC1 , AC2 , AC3 , AC4**...

**Hero D + Hero E** summoned **Hero DE1 , DE2 , DE3 , DE4**...

*Resulting in:*

**A , AB1 , AB2 , AB3 , AB4** <mark style="color:red;">can't be used to summon together</mark> as they have been summoned by **Hero A**.

*\* These rules are subjected to change during game development.*

## Summon Count

Each **NFT Heroes** can only be used to summon 7 times. After each time, the cost of using that Hero to summon a new Hero will increase. On the other hand, the chance of summoning a Hero with better equipment increases. The higher “**Summon Count**” a Hero is, the more valuable he can be.

## Cost of Summoning\*

Each time 2 Heroes are used to summon a new Hero, a certain amount of **HTD** are consumed. The higher “**Summon Count**” a Hero is, the more cost needed to summon a new Hero.&#x20;

## Degrade/Upgrade Rate\*

Depends on the Summon Count of each Hero participated in the summoning process, the % to create a Hero with better team will vary. Below is a table that describes the item degrade/upgrade rate corresponding to the Summon Count of the heroes in summoning process.
