Not sure why people don't like this idea, this would alleviate the need for some people to have them in the family inventory. I've seen countless people get multiple Valtarra proc's that will most likely never use them. With this, they can at least get another Mana Potion.

+1 & not sure if this has been suggested  previously considering this post is 2 years old(I apologize if it has)but upon obtaining the HP/MP potion on one character in your family the remaining members can accept a quest from the Black Spirit which will give them the appropriate inf potion(s), much like how the Adventurer's Tome Quest works currently upon unlocking it on one character. 

While there has been a lot of players asking for this basicly since PA brought infinite pots to the game, it not very likely to happen. PA replied to questions about that in one of their official streams that they dont want to do that for treasure items since it wud devalue them and devalue the effort of a lot of players that went trough the truble of making multiples and that they already made em easier to get with pity system but family inventory is a nogo.

I personaly wud love to see treasures placable in fam inventory, but i do understand why PA is reluctant to do so. Anyhow here is my +1 eventhough i dont belive it will happen.
