# Improve Rarity

![](/files/-MkcC1vZ9hHwvXO73NBP)

You have the possibility to improve the rarity of an Armz.\
To do so, you need 3 Armz of the same rarity.

Among them, 1 will be upgraded to a higher rarity, and the other 2 will be burned.

If they are Common, then it will become Rare.\
If they are Rare, then it will become Epic.

Epic cannot be upgraded to Legendary.

But, you have a 3% chance of getting an extra upgrade.\
So upgrade a Common to Epic, or a Rare to Legendary!

The cost in PROT varies depending on the rarity of the Armz being fed:

Common: $20 in PROT\
Rare: $30 in PROT

On top of that, 0.05 BNB is added as fee (see [***Tokenomics***](/a/prot/innovative-tokenomics.md) for more information)\
And **50% of these fees will be used to buyback PROT** and fulfil the contract that handles fights rewards.

**All PROT used for Improve Rarity are BURNED.**
