Faltered

Faltered is a state enemies in Doom Eternal enter when hit with certain attacks. A faltered enemy will immediately stop moving and cancel any attacks they were preforming. A soft falter is a falter that is triggered when an attack or series of attacks causes enough damage to reach or surpass a specific threshold set by the demon type. A soft falter can only be triggered once and only lasts about a second. A hard falter is caused by specific attacks, may be triggered indefinitely, and lasts about twice as long as a soft falter.

List of Attacks That Cause Hard Falters

 * Frag Grenade from the Equipment Launcher
 * Blast damage from the Microwave Beam mod on the Plasma Rifle
 * A remotely-detonated rocket from the Rocket Launcher
