Staggered & Stunned

Stance is affected by Force damage. Force dictates physical damage to the player and puts them off balance. Receiving too much Force damage causes the negative statuses Stagger and Stun.
Force which is generally associated with Ballistic attacks such as standard ammunition and Melee damage. However, each weapon and attack will have its own values, so it is important to pay close attention to Weapons, Armor, items, Skills, and Abilities to ensure the intended type of damage is being applied or guarded against. Base Stance regeneration is 10 points per second after avoiding all damage for at least 10 seconds.

Stagger

The Stagger mechanic dictates a character’s ability to engage in combat. The Stance meter is a visual representation of a player's susceptibility to being Staggered. Every hit or effect causing Force decreases the meter. The effects of being Staggered or Stunned are temporary but significant. Being Staggered or Stunned at the wrong time can be extremely dangerous.
The Stance meter has two thresholds - Staggered and Stunned. When the meter surpasses the Staggered threshold, the character gains the Staggered effect until the meter is positively increased beyond the threshold. The base effects for Stagger begin at 30% remaining Stance. Staggered causes a variety of negative effects:

• Forced Staggered animation for 3 seconds
• Movement speed is reduced by 25%
• Accuracy is reduced by 25%
• Recoil control is reduced by 25%
• Ability regeneration speed is reduced by 25%
• Any damage while Staggered interrupts and resets current actions such as reviving a teammate, any skill that requires charging, or using an item.

Players can reduce their Stagger risk and its effects by using specific armor, mods, items, and investing points into the Discipline and Resilience Attributes. Resilience reduces the effects of Force damage on the Stance meter and its reduction speed, while Discipline reduces the duration of being Stunned.
The Stance meter naturally and slowly regenerates over time, and the speed of regeneration can be increased with Attributes, skills, abilities, items, and more. Stance regeneration does not start until the character has been out of combat and not received damage for at least 10 seconds. The amount at which Stance is lost from attacks can be reduced by using abilities or items that have Force resistance. The amount of Force applied and Stance reduced depends on the ability or item used.
It is important to note that despite how much Stagger or Stun resistance a player has or their recovery speed for the effects, the maximum effective reduction value is 90%. Therefore, they can always be Staggered or Stunned. Additionally, some enemies may have attacks that have a higher chance of triggering the Stagger effect as well as being difficult to Stagger themselves.

Stun

Once the Stance meter is completely expended, the character becomes Stunned for a default of 8 seconds. During this period, they experience greatly enhanced negative effects:

• Forced Stunned animation until fully recovered.
• Unable to move, attack, or use abilities.
• Damage received is increased by 50%.
• Shield regeneration is stopped.
• Interrupts and resets all current actions.

Once a character recovers from being Stunned, their Stance meter is completely reset to 100%. To prevent locking players in a continuously Stunned state, the Stance meter cannot be impacted for 10 seconds after a Stun has been resolved.
