Damage Reduction is a stat that does exactly what it suggests: It reduces the amount of damage taken by a player or monster. Unlike other combat numbers that are complex calculations, a player's Damage Reduction is determined by simply adding together all Damage Reduction bonuses the player has, whether from equipment or something else like a 
Damage Reduction Potion or 
Leonardo.
Many monsters have Damage Reduction modifiers that affect their defensive stats.
Mechanics
Whenever a player or monster with Damage Reduction greater than 0% would receive damage, instead the damage they take is equal to:
[math]\displaystyle{ \text{Damage Taken} = \text{Base Damage} \times \left (1 - \text{Damage Reduction} \right ) }[/math]
Note that the Combat Triangle will affect how much damage reduction the player has if they are using a different style from the monster.
There is a hard cap of 95% on damage reduction. If a player or monster somehow reaches more than 95% total damage reduction, the excess will be ignored.
