How many skills are in Arc Raiders?

Forty-five nodes, split evenly across three trees of fifteen: Conditioning, Mobility and Survival. Each tree has exactly five major nodes and ten minor ones.

Is there a ninja skill tree in Arc Raiders?

No. There are three trees and none of them is called ninja or stealth, and neither word appears anywhere in the skill data. What exists is three noise-reduction nodes spread across the Conditioning and Survival trees: Gentle Pressure, Silent Scavenger and Suffer In Silence. A quiet build is assembled from those rather than picked from a dedicated tree.

What is the difference between a major and a minor skill node?

Major nodes are usually single-point unlocks: twelve of the fifteen majors accept only one point, so they grant a capability rather than a stacking bonus. Minor nodes mostly scale, with twenty-eight of the forty-five nodes accepting up to five points.

How many skill nodes have prerequisites?

Forty-two of forty-five. Each tree has exactly one entry node with no prerequisite, so the trees are almost fully gated.

Every node in all three skill trees, what it improves and what it costs in points. Includes the honest answer about the ninja build: there is no stealth tree.

How the tree is laid out

There are 45 skill nodes, split evenly across three trees of 15: Conditioning, Mobility and Survival. Each tree contains exactly five major nodes and ten minor ones.

Nodes come in two sizes. Twenty-eight of them accept up to 5 points and scale; the other seventeen are single-point unlocks that either you have or you do not. Twelve of the fifteen major nodes are single-point, so a major node is usually a capability rather than a bonus you stack.

Forty-two of the forty-five nodes sit behind at least one prerequisite, so the trees are close to fully gated: three entry points, everything else earned.

Survival is the looting and field-work tree. Crouching, crafting in a raid, carry weight, and two of the three nodes that reduce the noise you make. The other sits in Conditioning.

Node	Major	Max points	Improves	Effect
Agile Croucher	Yes	5	Movement Speed	Your movement speed while crouching is increased.
Good As New	Yes	1	Stamina Regeneration	While under a healing effect, stamina regeneration is increased.

Traveling Tinkerer	No	1	Field Crafting	Unlocks additional items to field craft.

There is no stealth tree, and no ninja tree

This comes up often enough to answer directly. The word ninja appears nowhere in the skill data, and neither does stealth. There is no fourth tree. What exists is 3 nodes spread across two of the three trees that reduce the noise you make:

Node	Tree	When it applies
Gentle Pressure	Conditioning	You make less noise when breaching.
Silent Scavenger	Survival	You make less noise when looting.
Suffer In Silence	Survival	While critically hurt, your movement makes less noise.

A quiet build is therefore assembled out of Conditioning and Survival rather than picked from a menu. If someone describes a ninja build, they mean those nodes plus Mobility traversal, not a tree the game offers under that name.

What this page does not know

The source records what each node does and what it improves. It does not record the size of any effect: how much less noise Silent Scavenger makes, how much faster Nimble Climber climbs. Those magnitudes are absent from the data, so no number for them appears above. It also does not record how skill points are earned or how many you can hold, which means this page cannot tell you whether filling one tree costs you another.
