Defense Basics — Resistances, Armour, Evasion, Energy Shield
In Path of Exile 2 you usually die not because your damage is too low, but because your defence is too low. Low damage just kills monsters a little slower; a broken defence ends the run on the spot. The Basics summed it up as “cap resistances and stack life first” — this page goes one level deeper into how each defensive layer actually works.
Resistances and maximum resistance
Resistance is the single most important defensive stat in the game. There are four types — Fire, Cold, Lightning, and Chaos — and the default cap for all four is 75%. 75% resistance means you take 75% less of that damage type.
The reason resistance comes first is that the campaign steadily applies a resistance penalty as you progress. Each act you clear lowers your resistances, and by the time you reach the endgame that accumulated penalty is large (commonly cited around −60%; check your character’s defence panel for the exact current value). So you keep patching that penalty with resistance on your gear to stay at 75%.
- Negative resistance means you take more damage — Cold resistance of −20% means 20% more Cold damage taken. That’s why the gap between “0 resistance” and “75%” is enormous.
- You can also raise the cap itself with “+X% to Maximum Resistance” modifiers (on some armours and jewels), letting you defend past 75%. That’s a later-game choice; as a beginner, the goal is simply to reach 75% first.
- Rings, amulets, and belts — which carry almost no damage — are the best slots to fill resistance.
Chaos resistance is a lower priority than the three elements: it’s hard to cap and usually survivable while negative during the campaign. Cap the elements first.
Armour · Evasion · Energy Shield
If resistances are the layer that reduces elemental damage, these three mostly handle physical and hit damage. They behave completely differently.
| Layer | What it does | Strong / weak against |
|---|---|---|
| Armour | Reduces physical damage | Strong vs many small hits / weak vs one big hit |
| Evasion | Makes enemy attacks miss entirely | Zero damage when it works / cannot evade spells |
| Energy Shield (ES) | A recharging buffer in front of Life | Refills after a lull / weak to damage-over-time |
- Armour reduces physical damage, but the reduction scales inversely with the hit size. It’s excellent against small, rapid hits and much weaker against a single blow that takes a big chunk of your health. (Making armour also apply to elemental damage needs specific keystones/supports — an advanced topic.)
- Evasion makes enemy attacks miss. It looks like pure luck, but it’s designed so that a run of evades guarantees the next hit lands (evasion can’t chain forever), so pair it with life rather than relying on it alone. Spell damage and some telegraphed boss attacks cannot be evaded.
- Energy Shield is extra health in front of Life that recharges on its own after a short window without taking damage. One 0.5 change: Chaos damage no longer passes straight through ES — instead it deals double to ES. And damage-over-time like Bleeding and Poison skips ES and hits Life directly.
Runic Ward — a new 0.5 layer
0.5 added a defensive layer called Runic Ward — a self-regenerating buffer that works separately from the three layers above. Damage is removed from Runic Ward first, and it refills over time.
You add Runic Ward to armour through Runeforging — using Verisium at the Verisium Anvil to swap an armour base for a Runeforged base. That process is covered in Expedition Crafting. It also shows up in places like the Reforging Bench at the Trial of the Sekhemas entrance (see Pinnacle Bosses).
Runic Ward’s exact activation and regeneration numbers aren’t firmly confirmed on trusted sources yet, so this page keeps it conceptual. Also note that Runeforging high-item-level gear can convert part of your existing Armour/Evasion/Energy Shield into Runic Ward.
Life · Mana · Spirit
- Life is where every defence ultimately ends up. All the layers above shave damage down, and Life absorbs whatever’s left — so maximum Life is the most reliable defence, working against every damage type. Even one Life roll per gear slot adds up.
- Mana mainly pays skill costs. It can also be a defence: the Mind over Matter keystone makes Mana take part of the damage headed for Life (at the cost of halved Mana recovery). That’s an advanced pick, not something to worry about early.
- Spirit is not a defensive stat — it’s a reservation resource. Persistent skills, auras, and permanent minions reserve Spirit while active; too little Spirit means fewer effects running. Its link to defence is that you run defensive auras (say, ones boosting resistances or evasion) off Spirit. Base Spirit comes from sceptre weapons and campaign quest rewards.
Practical priority
Following the order alone prevents most cheap deaths.
- Cap elemental resistances at 75%. The campaign penalty keeps draining this, so recheck the defence panel every time you change gear.
- Raise maximum Life. The most reliable layer after resistances.
- Pick one defensive layer. Follow the type of gear you’re wearing (armour / evasion / ES). Don’t try to mix all three early.
- When you have room, add extras like chaos resistance, higher max resistance, or Runic Ward.
