Fortification and Damage Reduction, Fortify Buff

PoE 3.19 Changes

Problem: Fortification is too difficult to gain for some melee builds, and too frustrating to use for many others.

Solution: Make fortification easier to gain and longer lasting.
  • Melee hits that can Fortify now generate roughly twice as many Fortification stacks as previously, based on damage dealt. Fortification generation against magic and rare monsters has been further increased.
  • The base duration of Fortification has been increased to 6 seconds (previously 5).
  • The entry small Passive Skill in the Steadfast cluster that provides increased Fortification for Fortifying Hits now has a value of 30% (previously 20%).
  • The top of the Steadfast cluster now consists of two small Passive Skills that each provide 40% increased Fortification Duration (previously one small Passive Skill that provided 20% increased Fortification for Fortifying Hits).

PoE 3.15 Changes

Fortify is intended to be a natural benefit of playing a Melee character, not a primary defence to invest in. Over time we've introduced larger values and more sources of Fortify effect, to the point where it can almost completely mitigate damage from hits. We're aiming for having "40% less damage taken from hits with Fortify" being on the upper end of defensive power achievable with heavy investment, so you can't rely entirely on Fortify. Hence all sources of fortify effect have been reviewed, almost all significantly nerfed or replaced with something that is okay to be stacked.

Fortification and Damage Reduction

Problem:
Fortification gain being scaled by the damage dealt by a fortifying hit means that hitting monsters with very high amounts of damage reduction (such as in the Azurite Mine, the Simulacrum or against monsters that have just been spawned by certain league mechanics) can grant little to no fortification, even for builds with very high damage.

Solution:
Fortification generation now ignores the target's damage reduction.
