Final answer:
Brimstone's Incendiary (Q) in Valorant deals 60 damage per second to players who remain in its fire zone, making it a potent damage-over-time ability.
Step-by-step explanation:
Brimstone's Incendiary ability in the game 'Valorant' is a damage-over-time ability. It deploys a grenade that creates a lingering fire zone, dealing damage to any players within its radius. The ability's damage output is contingent on the length of time a player stands within the incendiary area. As of the latest information prior to my knowledge cutoff in 2023, the damage per second (DPS) is 60, which means standing in the fire can be quite detrimental to a player's health over time, especially without healing abilities or a quick escape route.
