Defence (Defense) is a component which is used in almost all RPGs.
In Fiesta, this is used as a stat which can make you more protected and therefore, not die easily. This Stat is a main ingredient to becoming a Tanker.
This Stat can be found in the 'Character' icon, or you can just hit the hotkey , 'C'. See the picture to the right.
