STALKER 2 Psi Protection: What Actually Blocks It

The two sources

Psi zones. Certain structures and areas emit a field that damages you for as long as you stand in it. These are static, which makes them learnable: the same building hurts the same way every time you visit. Psi creatures. A small number of enemies attack with psi directly, and the more dangerous variants create hallucinations — copies of the creature that are not real, or false targets that draw your fire. Killing the source ends the effect; shooting the copies achieves nothing.

What protects you

Psi has its own resistance stat on suits and helmets. A suit with a high psi value takes a fraction of the damage, and a suit with none takes all of it. That is why the psi-protection question is an armour question first. Beyond gear, there are consumables that suppress psi effects for a duration. They are the right answer when crossing a zone rather than fighting in one, because a pill gets you through a corridor that no suit you own can tank.

The counter-intuitive part

Positioning beats protection. Psi zones have edges, and stepping out of the field stops the damage immediately. Players die by standing in a zone taking a pill instead of walking four metres backwards. Against psi creatures, the answer is target identification. If you see two of something that should be one, the one you can only sometimes see is the real one. Kill the source, and the hallucinations disappear with it.

What psi does not do

It does not replace physical damage. A psi zone near a mutant nest means taking two kinds of damage at once, and a build that resists psi but not bullets still dies.

The practical kit

One suit with real psi protection, one stack of suppression consumables, and the discipline to leave a field instead of fighting inside it. The armor page covers which suits carry the stat, and the radiation page covers the other hazard that ignores your physical protection.
