Currently the selection of ethers we have is…lacking, compared to food anyway. Speaking of food there are several ways to use less of it or none at all while with ethers you have to pack a ridiculous amount of or constantly pick more up, which is why I think we should have better ether options. I have 3 ideas that could help cut down on needed ether space significantly.
1: ethers that effect the entire team. bananas already do the same with hunger so it’s definitely implementable, plus it could be added to jello or elixers to add a reason to use them over ethers when playing alone
2: multi ethers. basically ethers that can be used more than once, not my favorite of the options however as it would likely be clunky and seem off.
3: bigger ethers. another simple one, ethers that over-fill your pp similar to golden apples, this one fits well, but may be hard to implement.
If even just one of these were added saving space in your bag would be much easier, and likely add reason to explore certain dungeons for supplies even more.
