This unusual Concoction boosts the imbiber’s reactions and speed for a very short time. When consumed, the imbiber may take two turns on the next combat round—one as the first turn of the round, and one as the last. This timing applies even if the imbiber’s side lost the Initiative. The Philter of Speed is only available as an Elixir.

However, the Philter puts a great strain on the imbiber’s system, inflicting 1d10 Vital damage per dose taken previously. (Vital damage is not reduced by Resistance or Damage Reduction of any sort, nor by any other means of reducing damage.) After one hour of not using the Philter of Speed, all traces of it are cleared from the body. This means that the first dose taken is safe, but later doses will quickly become deadly if the imbiber does not leave enough time to recover.
