# Boost Win Rate

![](/files/-MkcBrfwDGwgMOPZZ-Qv)

By giving PROT to your Armz, you have the possibility to improve its power and therefore its win rate.

You can do this 3 times per Armz.\
5% more win rate each time, for a maximum of 15% in total.

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

Common: $20 in PROT\
Rare: $30 in PROT\
Epic: $40 in PROT\
Legendary: $50 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 the Boost Winrate are BURNED.**
