Debuffs

While stunned, the target cannot act.

• No movement.
• No attacks.
• No ability casts.

A knock-up is the same disable with an airborne animation. It briefly lifts the target into the air and interrupts their action. The unit cannot act, move, or cast until it lands.

It lasts for a duration. It overrides their normal target selection. It is a targeting override, not a disable.

A taunted enemy still acts.

• It keeps attacking.
• It keeps casting.
• It only cannot choose whom to hit.

Frontline units use it to hold enemy damage on themselves. That damage then does not get through to the backline.

It delays that cast instead of preventing it. The unit still gains Mana at its normal rate. It simply needs more Mana before the Ability goes off.

It is a tempo debuff aimed at casters. It buys time instead of removing the cast.

Note: A Stun is different. A Stun interrupts a cast that is already happening.

It lasts for a duration. It is the debuff mirror of Damage Amp. Both use the same multiplier. Damage Amp is granted to the attacker, while Vulnerable is applied to the victim.

Note: It is not the same as Sunder or Shred. Each of those cuts one resistance stat. Neither one amplifies the hit itself.

The named Shred keyword works like this.

• It cuts Magic Resist by a percentage, commonly 30%.
• It lasts for a duration.
• With some sources it lasts for the rest of combat.
• It does not stack.
• A second Shred source on the same target adds nothing.

Other sources instead subtract a flat number of Magic Resist. Those work differently.

• The cut lands per hit or on a timer.
• These cuts keep adding up.
• The floor is 0 Magic Resist.

The named Sunder keyword works like this.

• It cuts Armor by a percentage, commonly 30%.
• It lasts for a duration.
• It does not stack.
• A second Sunder source on the same target adds nothing.

Other sources instead subtract a flat number of Armor. Those work differently.

• The cut lands per hit or on a timer.
• These cuts keep adding up.
• The floor is 0 Armor.

Each second it deals a percent of the target's maximum Health.

Most burn sources also apply Wound. Wound reduces healing received. Together, Burn and Wound are the standard answer to high-Health frontlines.

The set spells it three ways.

• A bleed.
• A poison.
• Plain wording like "damage over a number of seconds".

None of them share a keyword. So there is no single rule behind them.

The damage type also varies by source. Different sources tick as physical, magic, or true damage. This means no one resistance answers all of them.

Burn is the exception and keeps its own page. It is a real keyword with a rules gloss.

Note: Unlike Burn, nothing in the set reads these effects as a state. No other unit's ability checks whether its target is bleeding or poisoned. So each effect stands alone. Whether a second application stacks or refreshes is decided by the source that applied it.
