'''Defense''' is one of the core [[attributes]] for [[characters]] in [[Diablo III]]. It governs the amount of damage a character takes from all attacks, physical and magical.
Defense is '''''not''''' the same thing as [[Armor]]. The terms are confusingly similar in Diablo III, but Armor is what armor items grant. e.g. a buckler might have 8 armor while a tower shield might have 200. Armor helps increase a character's phyiscal damage reduction, just like the while Defense stat doesreduces all damage.
==Defense vs. Armorvs. Resistance==
The terms were used interchangeably in Diablo II, but in Diablo III they mean different things. The key thing to remember is that in Diablo IIIDefense, Armor works much like a resistance; it affects damage mitigation, not to/hit (as was the case in Diablo 1 and Diablo 2.) Higher Armor in Diablo 3 does '''not''' mean that your character gets hit less often. It means your character takes less damage per hit. This is one of the major changes Resistances are all stats used to the combat engine in Diablo III, and results in characters taking constant, steady damage, rather than the D2 style of attacks almost always missing, but when one does land it does huge reduce damage.
* Defense and Armor were used interchangeably in Diablo II, but in Diablo III they mean different things. The key thing to remember is a value on that in Diablo III, all types three of armor items.

Both Armor and * Defense increase is one of the four core character attributes/stats. It applies to all damage. It grows as your character's damage reductionlevels up, and can be added as a bonus from items, gems, but Defense offers much larger gainsskills, per pointand more. (But since high level * Armor is a value on all types of armor items . It only reduces damage from physical attacks.* Resistance can have many hundreds of points of Armor, both values must be cultivated for long term success.

Shot There are five different elements, and five corresponding resistance stats which reduce damage from the Diablo III betathose elements.]]
While defense does increase when you level up, it also has no effect until you acquire a certain amount of it. This amount increases with level which means that overall, Defense bonuses from level-up are largely superficial.
In terms of damage reduction, +3 Defense, +50 armor, and +5 resistance all give the same damage reduction to their respective damage types, however, mixing Defense with armor or resistance gives greater overall reduction than any one of them on its own.
