How? How is your campaign dead? Did you suddenly lose all of your FR stuff? If you started 14 years ago, you have the 3e FR stuff which in my opinion is the best stuff out there for it. I haven't seen the new book, so I don't know if I like it or not, but even if it stinks, it not can't kill...
I see it's still basically the Sword Coast. Calimshan and Icewind Dale are on that coast, and the Moonshaes are off of it. The only significant expansion away from the Sword Coast is the Dale Lands.
I also wish they had included Baelnorn in the bestiary.
It undercuts the action economy entirely. Why would potions be free use for their magical effect, but this rod over here takes an action to use? And that bonus action spell really takes as long(or even less time) to use as the potion, but isn't free.
For a significant magical effect, there...
Since it's healing potions that are the issue, rather than making it potions in general, perhaps something like taking a second healing potion within 30 seconds or a minute creates a magical conflict that causes the second potion to undo the healing of the first. You'd be down two healing...
Also an observant person shouldn't also automatically have excellent hearing. Someone who is a great long distance runner and awesome jumper shouldn't automatically be an amazing swimmer, especially if they've never been swimming.
I prefer more skills, but smarter people learn more of them...
Background plays a lot into who knows what in my game. A barbarian born and raised in the forest isn't even going to have to roll to know about common mushrooms in the forest. Learning those sorts of things will be cultural. When I was growing up I lived on a farm and one of the farmhands was...
Sometimes you know in advance, and sometimes you don't. Sometimes when you have advanced notice, you want to drink a potion. Potions being drunk before combat is sometimes of sometimes, which equates to rarely.
It may not be perfect, but it's a better solution than making them useless and almost never used because they take a full action and are almost always inferior to class/real magic item options.
As often as PCs get slammed backwards, knocked prone, fall 10+ feet, get hit by giants, ogres, trolls, weapons, etc., exposed potions like that(or on a belt) are likely going to be lost or shatter before you ever get to drink them.
