There are various comments about it being somewhat munchkin. This can be waved away by the simple expedient of saying 'almost' anything. The potion has a limited duration that necessitates multiple doses, the potion does not keep well, and the ingredients are hard to get - likely leaving a trail of crime that could be traced. I would expect any defenses against magic your game system provides to still be valid, so resistance rolls, saving throws and the like should still apply.
In short(?), a well detailed, well described potion that certainly fits the category of a wish-fulfillment item.
On presentation - there are quite a number of typos - prarie, interpitation, etc, and there is a lack of spaces after punctuation such as commas and periods. There is debate about whether you should have one space or two, but you need at least one :)
An interesting idea, but I can't help but think this needs higher then average agricultural technology then the typical peasant farm of the middle ages. The government who set this up must have been quite organized and wealthy! Go to Comment
Simple, but potent. I'm not a fan of mere mortals being able to manufacture indestructible items, but that is a minor flaw. More to the point when its worn it binds, hard, with the person's mind and while you could physically remove it, it would destroy the wearer.
