Silence

Silence is a status effect that prevents those affected from casting spells for the duration of the silence. It can be useful when ganking a hero with a blink or invisibility spell, as silences tend to have longer duration than other disables giving more time to kill the enemy. Silences in team fights can also be very effective even for a short time as they prevent the enemy from using their spell in combination with one another. Silencing an opponent will also stop any channeling spells that they are currently using.

Interactions
Silence prevents orb effect to be cast by both auto-cast and manually cast. Also, silence prevents toggling of applied spells.

Mute
Mutes are almost identical to silences, except they will also prevent the use of item abilities. Like silences, they will interrupt cast animations and channeling, but while silences will only interrupt channeled abilities, mutes will interrupt those from items as well.

Being muted will disable certain passive item and hero abilities and cancels the effects of some active ones. These include, but are not limited to:
 * Critical Strike
 * Cleave
 * Bash
 * Evasion, and Backtrack
 * Autocast Unique Attack Modifiers as well as many passive ones
 * Most sources of Lifesteal

There are only three sources of mute in Dota 2:
