Effect: Reduces the penalty to stamina regeneration when you are over-encumbered (carrying too much weight).
Purpose: The main benefit is allowing players to stay mobile and recover stamina more quickly even when heavily loaded with gear, which is vital for escaping threats and successfully extracting valuable resources during a raid.
According to sources like TheGamer and GamesRadar, it's considered a crucial skill for builds focused on looting and carrying a high volume of items, especially in late-game scenarios where valuable loot is abundant. Some player discussions suggest it was very impactful previously, but has since been "balanced" or slightly nerfed in its effectiveness, though it remains a viable option for a heavily-loaded playstyle.
The Stubborn Mule skill in ARC Raiders can be worth investing in if you frequently carry large amounts of loot and find yourself heavily over-encumbered, as it significantly reduces the stamina regeneration penalty. However, recent player feedback suggests it may have been silently nerfed and is not as effective as it once was, making its value dependent on your specific playstyle.
| Aspect | Stubborn Mule | Three Deep Breaths |
|---|---|---|
| Description | Designed for "loot goblins" and players who frequently carry heavy loads. | An endurance/mobility perk focused on high-intensity movement. |
| Effect | Reduces the stamina regeneration penalty caused by being over-encumbered. | Speeds up recovery after an ability (like jumping, dodging, or sprinting) completely exhausts your stamina. |
| Best For | Long looting sessions or "free loadout" runs where you lack carry-weight augments. | Combat-heavy builds and players who constantly sprint and slide around the map. |
| Performance | The first point provides a massive boost (up to 50% faster recovery at 100% encumbrance). Further points have diminishing returns. | It reduces the "exhaustion" period (when your bar blinks) from 3 seconds to 1 second at max rank. |
Choose Stubborn Mule if you often find yourself over-encumbered and vulnerable while carrying valuable loot.
Choose Three Deep Breaths for general play and better combat mobility, as it allows you to get back into the action faster after depleting your stamina.
Testing Results: At maximum level (5/5), testing indicates an approximately 11.6% increase in stamina regeneration while standing still and over-encumbered.
