Defense

Defense (or DEF for short) is representative of how much damage your Follower can sustain. Each time your Follower is dealt damage, DEF is subtracted from the defender's DEF according to the attacker's ATK (if that attacker is in Risen Position) or INT (if that attacker is in Rested Position). When a Follower's DEF becomes 0, it is sent to the Graveyard, and your character loses Life equal to the original Cooldown of that Follower.
