Break

Break is a status effect that disables passive abilities from those affected. It does not disable passive components from items such as evasion from Talisman of Evasion or critical strike from Daedalus.

Mechanics
Break disables passive abilities, but not passives of items. This means that for example is disabled, but  and derived items are not. It disables every aspect of the ability, including proc chances, innate cooldowns, attack modifier and permanent bonuses.

If a passive ability places a buff or debuff, already placed buffs/debuffs are not nullified. This means when for example an enemy is affected by Venomancer's Poison Sting, it continues to take damage and be slowed by the debuff even when Break is applied on Venomancer. The break only prevents Venomancer's attacks from applying the effect. The same also applies to passive abilities which grant stacks. Break just prevents them from gaining new stacks, but usually does not disable already existing stacks.

However, the opposite is the case for all disabled auras. The aura itself continues to place its buff/debuff on units, but when Break is applied on the source of the aura, the buff/debuff is disabled for the duration. If its status icon in the HUD shows values, they show 0 during Break

There is no set rule for which passive abilities are disabled by Break. however, most abilities which are needed by, or influence a second spell (for example and ) are not disabled.

Break works completely independent from mute and silence.
