Flame away but I don't really find "healing puddles" to be either immersion breaking or unrealistic(at least no more unrealistic than casting magic spells etc).
Magic healing potions are just that "MAGIC". I don't see why the substance can't be absorbed through the skin and has to be drank in order for it to work.
Right...because walking through a puddle of magical liquid that heals you when ingested due to it's magical properties should be able to work as well if you pour it out on the ground and go stand in it while wearing boots.
Snark aside I'll concede to your point on wearing boots, but stand by what I said about the healing ability being able to be applied through skin contact.
Ingesting it allows its properties to be absorbed through the flesh instantly. So why would it not work by pouring it into a wound itself to be absorbed through the flesh there or (with no boots on) absorbed through the flesh of the foot?
Edit: spelling
Edit 2: If healing potion took time to be ingested before they applied their healing ability I would not come to the conclusion I did. However they don't. Soon as it hits your mouth you are healed...aka the heal is absorbed before ingestion.
I mean, aside from it being completely bunk to just say "magic" as a catch all for a mechanic like that, it yet again removes another aspect of action economy where you have to choose whether or not to drink a potion; just toss one out on the ground in the first round if you don't have anything better to do and wait and walk on it as needed.
It's one of those changes, that was A) wholly unnecessary, and bring nothing to the game play and B) is just another DOS aspect that they've tossed into the game, that is completely incongruous with the DnD setting.
