I enjoyed this idea very much and the attempt to try and give it more of an alchemy flavor with the use of some ideas from chemistry and accidental explosions in the labs. Having watched a number of such things on a smaller scale, I liked the parallel very much. There should be some cost not just to the user of this dangerous potion but in the development of it also. The bit about increased stamina was clever too. The elixir by helping provide more oxygen to be available could help lessen the buildup of lactic acid from the depletion of oxygen during anerobic activities like combat. Go to Comment
This was a lot of fun to read. It might be more fun with having a way out in addition to timing to keep the playes guessing and fighting at the same time. As a spin on the idea, perhaps it could be used to carry or transport a lot of people to safety or prison? Perhaps a village of refugees could be rescued and passed by border guards? A bandit or criminal, etc., could be tricked by one individual slight of size but mighty of brain and transported for the reward money. Go to Comment
A secret MLM (pyramid) company that offers eternal life, but in fact it transfers the life forces of its members to those position "above". If you get high enough, (meaning you get enough new members) you start to enjoy the benefits. Maybe a willing sacrifice is much more effective for the transfer. But no one says, that a suddenly unwilling member, threatening to tell the authorities, may not loose it involuntarily... thus start people to vanish, and aged corpses are deposited somewhere safe.
