Stun

Stun

Stun is a Crowd Control strategy that causes an opponent to stop both movement and attack. If a stunned target is attacked, the stun remains in effect for the full duration (i.e. attacking the target does not break the stun).

Mesmerize, Stun, and Knock Down all stop a target from moving and attacking. However, they differ in the follow ways:

Skill	Effect on Target's Action	Effect on Target's Body	Can the Effect be Interrupted by an Attack on the Target? †
Stun	Target cannot Move or Attack	Remains Standing/Upright	Not Interrupted by Attack
Knock Down	Target cannot Move or Attack	Knocked to Ground	Not Interrupted by Attack
Mesmerize	Target cannot Move or Attack	Remains Standing/Upright	Interrupted by Attack

† Mesmerize can be interrupted (i.e. eliminated) if the mesmerized target is attacked, whereas stun and knockdown continue for the full duration even if the target is attacked.

Stuns apply a Resist Crowd Control on the target (which causes the target to become temporarily resistant to subsequent stuns/knockdowns/mesmerizes/roots/knockdowns).

The following abilities have a chance to stun an opponent, and are being tested/confirmed as to if they generate crowd control resistance. Please edit this page if you can confirm or deny resistance.

Ability	School	Is Resist Crowd Control Applied?
Crushing Blow	Bludgeon school	Yes
Knockback	Bludgeon school	Yes for Stun / Yes for Knock Back (Will apply two stacks of Crowd Control Resistance if both are applied.)
Ground Pound	Bludgeon school	Yes (Stun is only possible if player is Bludgeon Specialization)
Body Slam	Heavy Armor school	Yes
Gust	Air Magic	No for Knock Back / Yes for Stun
Discharge	Air Magic	Yes
Lightning	Air Magic	Yes
Chain Lightning	Air Magic	Yes
Lightning Storm	Air Magic	Yes
Charge	Shield school	Yes for the Knock Down / Yes for the Stun (Will apply double Crowd Control Resistance if both apply.)
Shield Bash	Shield school	Yes for Stun / Yes for Knock Back (Will apply two stacks of Crowd Control Resistance if both are applied.)
Sap	Subterfuge Skills	Yes for mesmerize (the tool tip is inconsistent: it uses both stun and mesmerize to describe the crowd control component. However, this skill appears to apply a mesmerize, and not a stun).
Chaos Bolt	Chaos Magic	Unknown/Untested
Flaming Bash	Shield school + Fire Magic	Yes for stun (the tool tip is inconsistent: it uses both stun and mesmerize to describe the crowd control component. However, this skill appears to apply a stun, and not a mesmerize).
Shield Smash	Shield school + Earth Magic	Yes for knockback; Stun is broken, so this skill does not stun (so a stun induced Resist Crowd Control never gets applied).
Shock Arrow	Ranged school + Air Magic	Unknown/Untested
Titan Smash	Bludgeon school + Heavy Armor school	No for Knock Back / Yes for Stun
Stone Fist	Earth Magic	Yes for Stun

Is there any mechanical difference between Stun and Knock Down other then the animation of being thrown to the ground?

Shield Bash lists effects as both stun and mesmerize. Is there any mechanical difference between stun and mesmerize?

Shield Smash is listed as having both knock back and stun effects, please confirm. If one is not true, remove from correct crowd control sub page.
