“Proc” is a common term used primarily in game programming to refer to an event triggered under particular circumstances.
For example, a particular weapon (that hits many times) might have a 10% chance on each hit to apply a special effect, such as poison damage.
For instance, “Bonus Damage” with the Warmaster Mastery…

Warmaster mastery is excellent for all Champions that is used for Clan Boss and any Dungeon boss since it has higher chance to deal high amount of damage compared to Giant Slayer. Warmaster proc does not count as a hit on Fire Knight Dungeon.
