The rapid-torch flamer's stats are almost identical to the stats of a regular flamer. The only element different compared to the normal flamer is attack animation. The difference in animation does have actual in-game impact, although minor. With the rapid-torch flamer, it's enough to quickly tap with mouse or trigger to fire the flamer, expending 1 point of ammunition in the process.
With the regular flamer, there is a slight delay before the gas get ignited which then propels fire, so in order to just expend 1 point of ammunition one needs to hold fire button a little bit (but not too long to expend two ammunition points). Therefore, with the rapid-torch, one can conserve ammunition a bit better than with a regular flamer.
It is weaker than the other unique flamer added by Broken Steel, the slo-burn flamer.
It can be more efficient than the slo-burn flamer, due to the fact that the rapid-torch needs to reload 1/3rd as often, and it deals more damage per unit of flamer fuel.
Without Pyromaniac it is about half as effective as the other unique flamer in the game, the Burnmaster.
It is still obtainable after Who Dares Wins is completed.
