Damage Reduction
There are 2 types of DR
Damage REDUCTION & Damage RESISTANCE
These do THE EXACT SAME THING, but because they aren't the same they stack, like how sneak attack, brutal attack, and death attack all do the same thing but stack because of different names
The highest of each only stacks though
If you have 5/- damage reduction and 5/- damage resistance, these will stack for effectively 10/-
If you have one source of 5/- damage reduction and a source of 6/- damage reduction, you only get the 6/-. Same for resistance
Stackable Damage Reduction
- Barbarian (including Epic Barbarian Damage Reduction)
- Earthkin Defender Earthkin Resilience
- Epic Damage Reduction
Note: Perfect Self uniquely stacks with Epic Damage Reduction but no other sources.
Unstackable Damage Reduction
Generally, when a creature has multiple sources of damage reduction, the one that reduces the most damage among those that are not overcome by an attack's enhancement bonus will apply. If there is a tie, the oldest reduction effect is used.
Examples:
- Premonition
- Stoneskin
- Greater Stoneskin
- Damage reduction from items such as Greensteel/Mithral/Adamantine Bracers
Damage Resistance
- Path of the Healer Cleric Divine Power
- Arcane Marauder Path Spellsword
- Elemental Avatar
- Shields dropped from the loot matrix
Notes
This is a WIP, merely making an easier-to-link resources for understanding how these mechanics work. Thanks to svrtr for providing the explanation.
