Shield Bash

Overview
Shield Bash is a card that can be found by knights while levelling up. It is an extremely strong card if you are in possession of a shield (Buckler, Shield or Heavy Shield). It is highly recommended to use this card along with a shield and upgrade it, since it gives you free critical strikes capable of dealing massive damage at the low cost of 10 EP. Not much strategy involved for this one, just get it, upgrade it, and use it.

This card is upgradeable and increases the number of strikes granted on each upgrade.

Shield Bash can only be found by Knights in a run while levelling up, but it is not guaranteed. It can also be passed to other classes by Knights.
