The Mobility Skill Tree in ARC Raiders focuses on maximizing movement efficiency and stamina management. It governs actions such as sprinting, vaulting, climbing, and dodging—essential skills for staying fast and agile in combat. While some nodes provide subtle improvements, others significantly enhance overall gameplay flow and endurance. This detailed breakdown ranks every Mobility skill by its real-world impact and practical usefulness ARC Raiders cheap weapons.

Core Movement Enhancements
Nimble Climber – Low A Tier
Increases climbing and vaulting speed.
The improvement is noticeable when directly compared, but not dramatic. On its own, this skill sits around B tier, but since players usually max it to progress deeper into the Mobility tree, its practical value rises to low A tier. It does exactly what it promises—nothing more, nothing less.

Marathon Runner & Youthful Lungs – S Tier
Improves stamina capacity and regeneration while running.
These two skills are almost mandatory. Running and stamina usage are constant, core mechanics, and these perks provide immediate, noticeable benefits. They are also required to reach later sections of the tree. Both are unquestionable S-tier picks.

Sliding, Falling, and Damage Mitigation
Slip and Slide – F Tier
Increases slide speed and distance.
The effect is so minimal that it is nearly impossible to notice. Even small inconsistencies in testing completely mask any improvement. This skill provides no meaningful gameplay value and is best skipped entirely.

Sturdy Ankles – Low C Tier
Reduces damage taken from non-lethal falls.
At maximum investment, the damage reduction is only about 10 health in noticeable falls. While technically functional, the benefit is too small to matter in most situations. Slightly better than Slip and Slide, but still underwhelming.

Ready to Roll – F Tier
Increases the timing window for recovery rolls when falling.
The default timing window is already extremely forgiving, making this upgrade almost irrelevant. A more meaningful improvement would have been enabling recovery from higher falls. As it stands, this skill offers no real value.

Dodge Roll Synergies
Carry the Momentum – B Tier
After performing a sprint dodge roll, sprinting does not consume stamina for a short time (with cooldown).
This is a decent one-point skill and is often taken simply to unlock deeper nodes. It’s useful but not exceptional, earning a solid B tier.

Effortless Roll – S Tier
Reduces stamina cost of dodge rolls.
This skill was recently buffed and now provides a major benefit. With no points invested, players can perform around six dodge rolls; when fully upgraded, this increases to roughly ten. Any skill that improves stamina efficiency this clearly and meaningfully deserves S tier.

Heroic Leap – F Tier
Increases the distance of sprint dodge rolls.
The improvement is extremely minor and only applies to sprint dodge rolls, making it even harder to notice. If it applied to all dodge rolls, it might reach a higher tier—but in its current state, it offers negligible value.

Walking, Crawling, and Wall Mechanics
Calming Stroll – F Tier
Stamina regenerates while walking as if standing still.
This only applies to a special slow-walk mode (often bound to Caps Lock), not normal walking. Testing shows stamina restores only about one second faster, while the reduced movement speed completely negates the benefit. Overall, this skill is inefficient and frustrating to use.

Crawl Before You Walk – B Tier
Increases crawling speed when downed.
The speed increase exists but is subtle and hard to notice during actual gameplay. It’s neither bad nor impressive—just a situational, average upgrade.

Off the Wall – F Tier
Increases distance of wall leaps.
Wall leaps are rarely used intentionally due to their clunky mechanics, and the improvement provided here is extremely small. This skill offers little practical value.

Vaulting and Climbing Specialists
Vigorous Vaulter – S Tier
Vaulting is no longer slowed when stamina is exhausted (also applies to climbing).
Although the description only mentions vaulting, this skill also affects climbing, which dramatically increases its value. Running out of stamina while climbing normally causes severe slowdowns, and this perk completely removes that issue. As a one-point investment, it is an easy S-tier choice.

Vaults on Vaults on Vaults – S Tier
Vaulting no longer costs stamina (also applies to climbing).
This is an extremely powerful perk, especially for movement-heavy playstyles. The main drawback is the requirement of 36 points in the Mobility tree, which forces investment into several low-tier skills. Despite that, the perk itself is strong enough to justify S tier placement.

Vault Spring – A Tier
Allows jumping at the end of a vault.
This one-point skill requires deep investment in Mobility, but if that path is already chosen, Vault Spring is highly recommended. It preserves momentum after vaulting and feels smooth and satisfying to use. While not game-changing, it consistently enhances movement flow, earning it A tier.

Conclusion
The Mobility Skill Tree in ARC Raiders offers a blend of outstanding stamina upgrades and disappointing filler skills. The true highlights—Marathon Runner, Youthful Lungs, Effortless Roll, Vigorous Vaulter, and Vaults on Vaults on Vaults—form the backbone of any efficient movement build. In contrast, skills like Slip and Slide or Heroic Leap add negligible value and are best avoided.

When chosen strategically, Mobility upgrades drastically enhance traversal speed, combat readiness, and overall game feel. For players who value agility and endurance, this tree delivers some of the most rewarding and fluid perks available in ARC Raiders.
