Shield Stun: how it works, mechanics

Mechanics

A shield bash on one target: deals no damage, may stun for 9 seconds. Base chance 80% - higher than the striking stuns of fighters and archers. The chance depends on the target's «CON», the difference between the skill level and the target's level, and its stun resistance. Duration enchanting brings the stun up to 20 seconds.

# How it works

«Shield Stun» is a melee strike on a single target, cast range 40. Base cast time 1.2 seconds plus a 0.3 second pause after the strike, cooldown 3 seconds. It needs a shield. The skill deals no damage.

The skill is learned by Human Knight - 15 levels, from character level 20 to 36; Paladin and Dark Avenger - up to skill level 52, from character level 40 to 74. Enchanting is available to their third professions: Phoenix Knight and Hell Knight.

While the target is under a stun from this same skill (the same level and the same enchant route), no new roll is made and the time is not refreshed. This skill of another level or another enchant route from another player stuns anew and replaces the previous stun.
A stun from another skill of the same power replaces the current one, even if it is shorter: the 20 seconds of the «Time» route can be replaced by 9 seconds.
The stun from «Armor Crush» is stronger: this stun does not land on top of it.
A hit on a stunned target can break the stun: a regular attack and direct physical damage skills break it with a 10% chance, their critical hit - with a 75% chance. Dagger skills with a lethal strike, skills with charges and magic do not break the stun.
On raid bosses the stun chance is half as high and the boss's «CON» is not counted, on Grand Bosses it is 5 times lower, on some 10 times. On regular monsters the chance is based on their «CON» and level, but many monsters have their own stun resistance, up to full immunity.
Cast time is given for «Atk. Spd.» 300: actual = base x 300 / «Atk. Spd.», but not less than 0.5 seconds.

# Stun chance

The stun chance depends on three things: the target's «CON», the difference between the skill level and the target's level, and the target's stun resistance. The result is never below 10% or above 90%. The higher the target's «CON», the lower the chance.

«STR», «P. Atk.» and the attacker's own level do not affect the chance. Stun power does - it comes from boss jewelry and a few skills. In the elemental enchant routes one more multiplier is added - from the weapon's attribute and the target's defense against that element.

# How the chance is calculated

Chance = base chance x target's «CON» multiplier x level multiplier x resistance multiplier. The result is not below 10% and not above 90%.

The base chance is 80% on all skill levels and with enchant.
«CON» multiplier: the target's full «CON» is used - with dyes, set and jewelry. Up to «CON» 27 the multiplier is 1, then it falls and at «CON» 50 reaches 0.10.
Level multiplier = 1.02 x (1 + (skill level - target level) / 100). The skill level here is not the character level: it is written in the skill itself and grows with its level and enchant. For skill level 52 it is 74, with any enchant - from 76 at +1 to 85 at +28.
Resistance multiplier = 1 + (attacker's stun power - target's stun resistance) / 100, not less than 0.10 and not more than 1.90. Both resistance and power are counted as no more than 150.

# Enchant

There are six enchant routes. «Recycle» shortens the cooldown from 3 seconds to 1. «Time» increases the stun time from 9 to 20 seconds. «Weaken Fire», «Weaken Water», «Weaken Wind» and «Weaken Earth» lower the target's resistance to one element for the duration of the stun - up to 50 at +30 - and make the skill itself elemental: their chance also depends on the element, see the next section. The table shows the written time: that is how long the stun lasts on a target without stun resistance. The enchant does not change the base chance of 80%, but any route raises the skill level in the chance calculation: from 74 to 76 at +1 and to 85 at +28.

What the routes give

Enchant	Cooldown in the «Recycle» route	Duration in the «Time» route	Element resistance reduction in the vulnerability routes	Skill level in the chance calculation	Chance on a level 85 target, «CON» 27	«CON» 43

+28	1.5 s	19 s	46	85	82%	34%
+30	1 s	20 s	50	85	82%	34%

# Element routes: the chance depends on the attribute

In the «Weaken Fire», «Weaken Water», «Weaken Wind» and «Weaken Earth» routes the skill itself becomes elemental, and one more multiplier enters the stun chance:

element multiplier = 1 + (attacker's element attack - target's resistance to this element) / 1000.

If the weapon's attribute matches the route's element, element attack = weapon attribute + 20 from the enchant.
If the weapon has a different attribute, the enchant adds no element: only the attack of this element from other sources (augmentation, agathion, potions) goes into the calculation - usually from 0 to 20, and the multiplier almost always lowers the chance.
Target's resistance is the sum of its resistance to this element from armor and buffs.

Conclusion: an element route is worth taking only to match the attribute of your own weapon. With a weapon of another element, against a target with resistance 300 the chance drops by 30% of its value. The other routes do not have this multiplier.

# How to protect yourself

Stun resistance protects from stun: it lowers the chance and shortens the duration. Resistance 40 leaves 60% of the chance calculated from «CON» and level, resistance 80 leaves 20%. The attacker's stun power is subtracted from the target's resistance. General debuff resistance, «M. Def.» and mental resistance do not affect stun.

What else cancels the stun

What is on the target	What happens
immunity to debuffs or invulnerability	the stun does not land
evasion of physical skills	does not help: the skill deals no damage and cannot be evaded
a shield equipped (not a sigil), the attacker within the target's block sector	with a 10% chance - a perfect block: the stun does not land
reflection of physical skills	with the reflect chance the skill bounces back to the attacker: the stun is then rolled on his «CON», level and defense, and the target does not get it

# How long the stun lasts

The skill states 9 seconds, with the «Time» enchant - from 10 to 20 seconds. The target's stun resistance shortens the duration, the attacker's stun power lengthens it. Against raid bosses the duration does not change.

How it is calculated: difference = the attacker's stun power - the target's resistance.

The difference is zero (no resistance, or the power fully cancels it): the time equals the written one.
Difference below zero (resistance is stronger): duration = 9 / (1 + difference / 100), the difference is taken without its sign.
Difference above zero (power is higher): duration = 9 x (1 + difference / 100).
The result is rounded down to whole seconds.

Example: the target has «Resist Shock» level 4 - resistance 40. An attacker without stun power: difference -40, time 9 / 1.4 = 6.43, rounded down to 6 s. An attacker with «Improved Earring of Antharas» with power 40: difference 0, time 9 s.

# Gear and buffs: what changes the chance

«STR», «P. Atk.» and the attacker's usual buffs do not change the stun chance - only stun power does, and in the element routes also the weapon's attribute. On the target's side the chance is changed by «CON» and stun resistance.

Measurements: Phoenix Knight level 85, enchant +30 «Time», target - Duelist level 85 («CON» 43), 4000 uses per cell. The skills and jewelry in the tests are real. Time in these tables is recalculated by the formula after the fix of 14.10.2026 (verified by a test on the core), chance is measured.

# In battles on the server

Data from the log of battles between players over 06-11.10.2026, seven stun skills together: «Stun Attack» , «Hammer Crush» , «Armor Crush» , «Rush Impact» , «Rush Impact» , «Stun Shot» , «Shield Stun» . The log does not mark the Olympiad separately, its fights are included in the total.

Key point: in real fights the chance is almost always cut by the target's resistance. «Resist Shock» level 4 from a buffer or its event copy was on the target in 68% of rolls, and almost half of all rolls (46%) went with the minimum chance of 10%. The target had «CON» above 27 in 93% of rolls. The attacker's stun power outweighed the target's resistance in only 7% of rolls.

# Specifics of our server

The skill's logic is as close as possible to the official High Five servers (PTS). All the numbers are taken from their data: base stun chance 80%, duration 9 seconds, cooldown 3 seconds. Nobody knows for certain how exactly the official server calculates the stun chance and duration inside: there is no public description, and the known builds interpret the same numbers differently. So where the data leaves a choice, on our server the rule is set explicitly:

Stun resistance works twice: it lowers the chance and shortens the stun duration. The attacker's stun power works the other way - it raises the chance and lengthens the duration.
Stun resistance and stun power are counted as no more than 150 each, the final chance is not below 10% and not above 90%.
The time is calculated only from the difference between the attacker's stun power and the target's resistance: on an unprotected target, as with equal power and resistance, the stun lasts exactly the written time - 9 seconds (20 seconds with the +30 «Time» enchant).
A regular hit and a direct physical damage skill break the stun with a 10% chance, their critical hit - with a 75% chance.
While the target is under a stun from this same skill, no new roll is made and the time is not refreshed.
Against raid bosses the chance is half as high, against Grand Bosses - 5 times lower.
In the element enchant routes the stun chance is multiplied by the element multiplier: the weapon's attribute against the target's resistance.
