Brand, the Burning Vengeance, is a mage champion in Riot Games' League of Legends, and Pillar of Flame is his W ability, which calls down a column of fire after a short delay. The existing listing describes this clip as Brand using Pillar of Flame, and that matches the short fiery eruption heard here. Ability sounds like this get ripped for soundboards because they are clean, punchy and instantly recognisable to players. It remains popular in montages and memes as a generic fire-impact cue, even for viewers who have never played the game.
